Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.
Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.
Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.
Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101
In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.
As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.
I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.
You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101

There are some errors I noticed after upgrading my flow version. I had them in my project, and they were also reported in #11655. These errors were ignored on master, but I went through and fixed them so the static analysis will work still.
After these changes, I receive no errors using flow `0.60.1` on latest master, or using `0.59` in my local project (which does not have the requisite ignores included).
- init a new project
`react-native init --version <path-to-repo> helloworld`
- add the flow binary
`yarn add -D flow-bin`
- run flow
`yarn flow`
- make sure there are no errors in the project.
```
No errors!

I want to animate `shadowOpacity` style property with Native Animated (`useNativeDriver: true`). This is useful for example in an ios-like navigation transition where the shadow fades in with the view that is sliding in from the side. Code comment for `STYLES_WHITELIST` says:
_In general native animated implementation should support any numeric property that doesn't need to be updated through the shadow view hierarchy (all non-layout properties)._
so I just added `shadowOpacity` (and `shadowRadius` too because why not?).
Before this change, setting `shadowOpacity` (or `shadowRadius`) to an `AnimatedValue` (with `useNativeDriver: true`) would throw the error: `Style property 'shadowOpacity' is not supported by the native animated module`.
After adding `shadowOpacity` (and `shadowRadius`), there is no error. The animation looks correct so it seems to be working. I also tried setting a ridiculously large `shadowRadius` and could see that working too.
Please advice on any further testing I should do.

Summary:
As I was working on mimicking iOS animations for my ongoing work with `react-navigation`, one task I had was to match the "push from right" animation that is common in UINavigationController.
I was able to grab the exact animation values for this animation with some LLDB magic, and found that the screen is animated using a `CASpringAnimation` with the parameters:
- stiffness: 1000
- damping: 500
- mass: 3
After spending a considerable amount of time attempting to replicate the spring created with these values by CASpringAnimation by specifying values for tension and friction in the current `Animated.spring` implementation, I was unable to come up with mathematically equivalent values that could replicate the spring _exactly_.
After doing some research, I ended up disassembling the QuartzCore framework, reading the assembly, and determined that Apple's implementation of `CASpringAnimation` does not use an integrated, numerical animation model as we do in Animated.spring, but instead solved for the closed form of the equations that govern damped harmonic oscillation (the differential equations themselves are [here](https://en.wikipedia.org/wiki/Harmonic_oscillator#Damped_harmonic_oscillator), and a paper describing the math to arrive at the closed-form solution to the second-order ODE that describes the DHO is [here](http://planetmath.org/sites/default/files/texpdf/39745.pdf)).
Though we can get the currently implemented RK4 integration close by tweaking some values, it is, the current model is at it's core, an approximation. It seemed that if I wanted to implement the `CASpringAnimation` behavior _exactly_, I needed to implement the analytical model (as is implemented in `CASpringAnimation`) in `Animated`.
We add three new optional parameters to `Animated.spring` (to both the JS and native implementations):
- `stiffness`, a value describing the spring's stiffness coefficient
- `damping`, a value defining how the spring's motion should be damped due to the forces of friction (technically called the _viscous damping coefficient_).
- `mass`, a value describing the mass of the object attached to the end of the simulated spring
Just like if a developer were to specify `bounciness`/`speed` and `tension`/`friction` in the same config, specifying any of these new parameters while also specifying the aforementioned config values will cause an error to be thrown.
~Defaults for `Animated.spring` across all three implementations (JS/iOS/Android) stay the same, so this is intended to be *a non-breaking change*.~
~If `stiffness`, `damping`, or `mass` are provided in the config, we switch to animating the spring with the new damped harmonic oscillator model (`DHO` as described in the code).~
We replace the old RK4 integration implementation with our new analytic implementation. Tension/friction nicely correspond directly to stiffness/damping with the mass of the spring locked at 1. This is intended to be *a non-breaking change*, but there may be very slight differences in people's springs (maybe not even noticeable to the naked eye), given the fact that this implementation is more accurate.
The DHO animation algorithm will calculate the _position_ of the spring at time _t_ explicitly and in an analytical fashion, and use this calculation to update the animation's value. It will also analytically calculate the velocity at time _t_, so as to allow animated value tracking to continue to work as expected.
Also, docs have been updated to cover the new configuration options (and also I added docs for Animated configuration options that were missing, such as `restDisplacementThreshold`, etc).
Run tests. Run "Animated Gratuitous App" and "NativeAnimation" example in RNTester.

Summary:
AnimatedImplementation.js is getting pretty hard to navigate and reason about so I split it up into different modules. Also took the opportunity to run prettier on that code and do some minor const/let refactorings. This doesn't change any logic, mostly just moves code around and add proper imports / exports.
This opens the door for further cleanup and flow type improvements but want to keep this already big PR as small as possible.
Discussion points:
- Should I use haste for this? Animated is pretty much a standalone module, it still uses a few haste imports but for new modules I used commonjs imports to avoid polluting the haste global namespace too much. The new modules are all internal to Animated and should not be imported externally.
- We're using `requestAnimationFrame` from fbjs instead of the one available globally in RN and browsers is there a reason for that?
- Should we even support web in this implementation? There is a standalone repo that exist for Animated web. Is this implementation of Animated web used internally at facebook?
- Probably still related to web, we used some weird Set polyfill is that still needed?
Notes:
There is a small regression for docs where the type of some classes that are exported like AnimatedValue show up as CallExpression instead if Class.

Summary:
At present, there's no uniform way of determining whether you've received an Animated value node which can be attached to an animated prop.
You can attempt to use `instanceof Animated.Value`, but this fails for interpolated values. You can use `instanceof Animated.Interpolation`, but this fails for the values that are returned from the math functions (e.g., `Animated.Add`).
This commit exposes the base type from which all of these value nodes derive. As such, it is now possible to do the following:
```js
import React, { Component, PropTypes } from 'react';
import { Animated } from 'react-native';
class Widget extends Component {
static propTypes = {
progress: PropTypes.instanceOf(Animated.Node).isRequired,
}
// ...
}
```

useNativeDriver: true. But fails on android and skips the first stage
of animation on ios.

When using native animated we don't go through the shadow thread and use the NativeViewHierachyOptimizer so we have to make sure the views won't get optimized away.

Summary:
This re-implements sticky headers in JS to make it work on Android.
The only change that was needed was to expose a way to attach a an animated value to an event manually since we can't use the Animated wrapper and `Animated.event` to do it for us because this is implemented directly in the `ScrollView` component. Simply exposed `attachNativeEvent` that takes a ref, event name and event object mapping. This is what is used by `Animated.event`.

Summary:
After taking a look at the existing animation docs, I found that most of the documentation on using `Animated` was spread out throughout the Animations guide and the `Animated` API reference, without any particular structure in place.
This PR aims to clean up the API reference, focusing on documenting all the provided methods exhaustively, and deferring to the Animations guide for long form examples and supporting content.
The `Easing` module is referred to at various points in the API reference, so I decided to clean up this doc as well. easings.net provides some handy visualizations that should make it easier for the reader to understand what sort of easing curve each method provides.
The site was built locally, and I verified all three documents render correctly.

Summary:
findNodeHandle is considered an internal module. The one to use is ReactNative.findNodeHandle. We need to rely on this because we will have two different renderers and we need the renderers to inject themselves with findNodeHandle before it is used.
I use ReactNative.findNodeHandle from inside the module because I think this leads to a cycle somewhere or might not play well with inline require otherwise.
There is also one in UIManager but that is definitely a cycle so I'm going to try to avoid that one.

Summary:
The `extractOffset` method is previously implemented on `Animated.Value`, along with `setOffset` and `flattenOffset`. Both of the latter methods are proxied on `Animated.ValueXY`, but `extractOffset` is not. This commit adds the missing method.
When creating draggable elements in XY space, in order to compensate for previous gestures' offsets, we currently need to do something like the following at the beginning or end of each gesture:
```
xy.setOffset(xy.__getValue());
xy.setValue({x: 0, y: 0});
```
After this commit, the API is equivalent to using a plain `Animated.Value`:
```
xy.extractOffset();
```

Summary:
On iOS, when you press down native fading components, they become
transparent instantly, but then have an animated fade in/out if you
move your finger in/out of their hit box.
On react-native currently, the touchdown fades, instead of providing
instant feedback, which doesn't feel right on iOS.
I'm less familiar with Android conventions, but it seems to use fading
components for buttons less often, instead using the ripple effect from
TouchableNativeFeedback. In either case, instant feedback seems better
for the user.

Summary:
`flattenOffset` has proven extremely useful, especially when dealing with pan responders and other gesture based animations, but I've also found a number of use cases for the inverse. This diff introduces `extractOffset`, which sets the offset value to the base value, and resets the base value to zero. A common use case would be to extractOffset onGrant and flattenOffset onRelease.

Summary:
Native Animated.Value uses the value it was created with when sending the config to native but this causes issue when the value has changed before calling `__makeNative` this happens with the `progress` value for `NavigationExperimental`. It gets initialized with value 1, then uses `setValue` to change it to 0 before starting the animation and this is when `__makeNative` is called. This simply uses the current value instead of the value passed to the constructor. Also pass offset so native implementations that support it can use it (iOS).
**Test plan**
Tested that the first transition that uses the `progress` animated value is not broken in an app that uses `NavigationExperimental` when using `useNativeDriver` for animations.

Summary:
Combining 2 animated values via addition, multiplication, and modulo are already supported, and this adds another one: division.
There are some cases where an animated value needs to invert (1 / x) another animated value for calculation. An example is inverting a scale (2x --> 0.5x), e.g.:
```
const a = Animated.Value(1);
const b = Animated.divide(1, a);
Animated.spring(a, {
toValue: 2,
}).start();
```
`b` will then follow `a`'s spring animation and produce the value of `1 / a`.
The basic usage is like this:
```
<Animated.View style={{transform: [{scale: a}]}}>
<Animated.Image style={{transform: [{scale: b}]}} />
<Animated.View>
```
In this example, the inner image won't get stretched at all because the parent's scaling gets cancelled out.
Also added this to native animated implementation.

Summary:
This adds support for `Animated.event` driven natively. This is WIP and would like feedback on how this is implemented.
At the moment, it works by providing a mapping between a view tag, an event name, an event path and an animated value when a view has a prop with a `AnimatedEvent` object. Then we can hook into `EventDispatcher`, check for events that target our view + event name and update the animated value using the event path.
For now it works with the onScroll event but it should be generic enough to work with anything.

Summary:
see also: eb3360b02a (commitcomment-19042340)
commit eb3360b02a recently break some third libraries that was (weakly) relying on traversing `animatedNode.refs.node` to get the original node of the decorated (animated) component (at least 2 libs: gl-react-native and react-native-material-kit).
Instead of now doing `animatedNode._component` (that might later break again), getNode() is a more 'public' solution for these third party.
as you expose a way to create an animated component (`createAnimatedComponent`) you sometimes still want a way to get the reference.
That way, third party components can continue providing some extra native methods to the animated version.

Summary:
This adds a new type of node that clamps an animated value between 2 values with a special twist, it is based on the difference between the previous value so getting far from a bound doesn't matter and as soon as we start getting closer again the value will start changing. The main use case for this node is to create a collapsible navbar when scrolling a scrollview. This is a pretty in apps (fb, youtube, twitter, all use something like this).
It updates using the following: `value = clamp(value + diff, min, max)` where `diff` is the difference with the previous value.
This gives the following output for parameters min = 0, max = 30:
```

0 0

This adds support for the `transform` animated node. This brings feature parity with the iOS implementation and allows running the NativeAnimated UIExplorer example that was created with the iOS implementation on Android. This is based on some work by kmagiera in the exponent RN fork.
This also adds support for mixing static values with animated ones in the same transform as well which is not supported on iOS at the moment. It is also implemented in a way that rebuilds the transform matrix the same way as we build it in JS so it will be easy to remove some of the current limitations like forcing the transforms order and only supporting one of each type.

Summary:
This diff addresses the issues raised by kmagiera in https://github.com/facebook/react-native/pull/7884. Transforms should be applied in the order they are defined, just like in `processTransform.js`. A scale applied before a translation, for instance, should give a different result than a translation applied before a scale.
We leverage CATransform3D to do the heavy lifting. A concatenated transform is passed all the way to `RCTViewPropertyMapper`. It is compared with the transform currently applied to the view, and if different, applied. The same approach is used for opacity.
I think it makes the most sense to do this diffing in `RCTViewPropertyMapper`, as opposed to creating and cleaning up an `_updatedPropsDictionary` each frame in `RCTTransformAnimatedNode` and `RCTStyleAnimatedNode`. The node should keep its full value; applying a minimal set of altered props is an optimization. The higher up this optimization is implemented, the more assumptions it makes. e.g. that there will only ever be a sing

Summary:
This change fixes an issue with calling `setValue` for natively driven nodes. As of now an attempt to call this method from JS would trigger an error "Attempting to run JS driven animation on animated". That is because for natively animated nodes we don't allow for `setNativeProps` to be executed and method `_flush` is now responsible for triggering that call. To fix the issue we add extra flag to `_updateValue` method that indicates if we should be "flushing" updated values using `setNativeProps` and we pass an appropriate value depending on the status of the node (native/non-native). Note that in animation callback we always pass `true` - that is because natively driven animations will never call into that callback.

Summary:This change adds native animated support for Animated.interpolate
Animated.interpolate allows for defining nodes that outputs an interpolated value of their input node based on the interpolation node configuration. For now native animated implementation only supports a linear interpolation for a given input and output ranges (ranges can consists of multiple segments). Native interpolation node is compatible with the JS implementation with the exception that not all attributes that can be used in JS are supported. Before we migrate interpolation node from JS->native we verify that only supported props are used.

As JS thread runs in parallel to the thread which executes the animation there is a chance that JS may call `stopAnimation` after the animation has finished. Because of that we are not doing any checks on the `animationId` parameter passed to `stopAnimation` in native and if the animation does not exists in the registry we ignore that call.

Summary:The CSS spec doesn't allow for decimal values inside of rgb colors, however the RN implementation does, so there was a disconnect here.
This tests to see if the output range is an rgb color, and if so, rounds the first 3 interpolated components (but not the 4th, since that would be opacity and allows for a decimal).

Summary:This is the first from the series of PRs I'm going to be sending shorty that would let Animated.js animations to run off the JS thread (for Android only).
This PR introduce a new native module that will be used for offloading animations - NativeAnimatedModule. It has a simple API that allows for animated nodes management via methods like: create/drop animated node, connect/disconnect nodes, start animation of a value node, attach/detach animated from a native view.
Similarly to how we handle UIManager view hierarchy updates we create a queue of animated graph operations that are then executed on the UI thread. This isolates us from problems that may be caused by concurrent updates of animated graph while UI thread is "executing" the animation.
The most important class NativeAnimatedNodesManager.java implements a management interface for animated nodes graph as well as implements a graph traversal algorithm that is run for each animation frame. For each animation frame we visit animated nodes th

Summary:This is an initial take on how to allow for value wrapping in Animated (currently `.timing` only). It adds a wrap config options which is an array specifying a range of values to be wrapped around. Anytime the delta of `toValue and fromValue > wrapDistance / 2` instead of animating the long way it will animate towards the range extremity and then after breaching the range it will readjust to animated to the true toValue.
Example Usage:
```js
Animated.timing(
this.state.animatedDegrees,
{toValue: Math.random()*360, wrap: [0, 360]}
).start()
```
This is presumably very valuable in rotation based animations, but could also be useful in other applications like wrapping the edges of the viewport.
Questions & Todo:
- Is `wrap` as a config key semantically meaningful and accurate?
- Is there a way to expose this as a config option on `.interpolate` rather than timing
- Generalize to all animated API's (spring, decay), and will this work with ValueXY out of the box?
- Add tests

Summary:This adds support for passing plain numbers into the add and multiply operators. This can be useful if you want to have one AnimatedValue for a component that is say a scale 0 -> 1 and then animated many style properties accordingly using derivative Animated values.
Thoughts?
As far as implementation, there may be more performant implementations that do not require creating a whole new AnimatedValue for every static number. I am open to suggestion.

Summary:
**Problem:**
As I was trying to document what color formats we supported, I realized that our current implementation based on the open source project tinycolor supported some crazy things. A few examples that were all valid:
```
tinycolor('abc')
tinycolor(' #abc ')
tinycolor('##abc')
tinycolor('rgb 255 0 0')
tinycolor('RGBA(0, 1, 2)')
tinycolor('rgb (0, 1, 2)')
tinycolor('hsv(0, 1, 2)')
tinycolor({r: 10, g: 10, b: 10})
tinycolor('hsl(1%, 2, 3)')
tinycolor('rgb(1.0, 2.0, 3.0)')
tinycolor('rgb(1%, 2%, 3%)')
```
The integrations of tinycolor were also really bad. processColor added "support" for pure numbers and an array of colors!?? ColorPropTypes did some crazy trim().toString() and repeated a bad error message twice.
**Solution:**
While iteratively cleaning the file, I eventually ended up reimplementing it entierly. Major changes are:
- The API is now dead simple: returns null if it doesn't parse or returns the int32 representation of the color
- Stricter parsing of at

Summary:
This PR was created in response to feedback from an older PR: https://github.com/facebook/react-native/pull/2045
The `.interpolate()` API of Animated values is quite effective to accomplish transformations based on a single animated value, but currently there is a class of animations that is impossible: animations being driven by more than one value.
Usage would be like the following:
```js
getInitialState: function() {
return {
panY: new Animated.Value(0),
offset: new Animated.Value(0),
};
}
```
```js
var scale = Animated.add(panY, offset).interpolate({
inputRange: [...],
outputRange: [...],
});
```
I have a real use case for this, and I cannot think of any way to accomplish what I need without an API like this.
The animation I am trying to accomplish is I have a PanResponder being used to detect both x and y panning. The y-axis panning drives a 3d sroll-like animation (which we can call `panY`), and the x-axis panning is driving a "swipe-to-remove" animation (

Summary: Adds a new option to animation configs so that animations can be marked as non-interactions. This solves the "loading indicator problem" where an animated loading screen would deadlock as it waits for all interactions to complete.
As for the API, what we really want long term is better scheduling. This needs to be built at the runtime level (into the RN bridge) and take care of things like priority donation that are probably overkill right now. Basically this API is a medium-term fix and I won't be upset if it gets replaced with a finer-grained scheduler.

Summary:
1) Makes params more intuitive (only one now, bounciness, which maps intuitively to number of oscillations).
2) Satisfies boundary conditions (f(0) = 0, f(1) = 1) so animation actually goes where you tell it (before it would finish at a random location depending on the input params).
3) Simple test to verify boundary conditions.
