Kevin Gozali 3237ade34f fallback to JS Animation if native animated is not present
Summary: This should be a temporary migration path until we enable native animated everywhere, instead of crashing the app if the module is missing. This would present a yellow box with an instruction to add RCTAnimation module to the app

Janic Duplessis 2b49eddcfd Fix initial value of native Animated.Value
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.

Kevin Gozali 0a0dd30c6a Introduced AnimatedDivision
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.

Janic Duplessis 6565929358 Add support for animated events
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.

Gaëtan Renaudeau 19d0429a76 Expose getNode() on component created with createAnimatedComponent
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.

Janic Duplessis cd1d652af4 Add AnimatedDiffClamp node
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:
```
  in     out
  0      0
  15     15
  30     30
  100    30
  90     20
  30     0
  50     20
```

One issue I see is that this node is pretty specific to this use case but I can't see another simple way to do this with Animated that can also be offloaded to native easily. I'd be glad to discuss other solutions if some

Janic Duplessis df05311777 Add transform support for native animated on Android
Summary:
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.

**Test plan (required)**

Tested with the NativeAnimated example on Android and iOS. Also tested mixing in static values in a transform (`[{ rotate: '45deg' }, { translateX: animatedValue }]`).

Ryan Gomba eb96b7fabc Maintain transform order
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

Brandon Withrow 19e2388a76 Add support for native animations on iOS
Summary:
Currently on iOS animations are being performed on the JS thread. This ports animations over to the native thread and performs them natively. A lot of this work has already been done on Android, but this PR enables a few animation nodes that Android doesn't yet support such as Transform, Multiplication, and Addition nodes.
Also there is a demo of the native animations added to the UIExplorer app.

Sean Kelley 908041b80b Round alpha channel when interpolating colors to the nearest thousandth.
Summary:
This fixes an issue where animations for values near zero could end up formatted
with exponents (e.g. `1.452e-10`), which is not valid for an `rgba` color spec.
This commit arbitrarily rounds it to the nearest thousandth to prevent this type
of formatting while still maintaining high-enough resolution in the alpha channel.

One way this could bubble up to the user is as PropType validation failures:

```
Failed propType: Invalid prop `backgroundColor` supplied to `RCTView`: rgba(0, 0, 0, 9.838983123336224e-7)

Krzysztof Magiera 6c80f886ae Fix setValue to work properly on natively driven nodes
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.

Krzysztof Magiera dd244f5530 Support for Animated.interpolate
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.

Krzysztof Magiera cd11738819 Support for stopping animations that run on UI thread.
Summary:This change extends animated native module API with `stopAnimation` method that is responsible for interrupting actively running animation as a reslut of a JS call. In order for the `stopAnimation` to understand `animationId` argument I also had to add `animationId` to `startAnimation` method. 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).

Krzysztof Magiera 65ccdffc8d Execute Animated.js declarative animation on UIThread on Android.
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

Zack ae0ad1fc7e Implement modulo operator method
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

How it works:

1. If code is pushed to `master` branch then CI will build a fresh version of docs and put it in https://github.com/facebook/react-native/tree/gh-pages/releases/next folder.
Github will serve this website from https://facebook.github.io/react-native/releases/version/next URL.

Christopher Chedeau c8a0a3eff6 Reimplement color processing
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

Leland Richardson 3eb32cbb0e Animated.multiply and Animated.add to combine animated values
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 (

James Ide c38d7fab97 `isInteraction` option to keep InteractionManager unblocked
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.

Sebastian Markbage 2ea3b93784 Add warning to setNativeProps and Animated for non-nested styles
Summary: These were accidentally supported because they were merged at a lower
level. That's an implementation detail. setNativeProps should still
normalize the API.

I fixed some callers.

Setting props the normal way used to ignore these. Unfortunately we can't
warn for those cases because lots of extra props are spread. (The classic
transferPropsTo issue.)

Christopher Chedeau a50b4ea7b9 Initial web implementation
Summary: @​public

This diff does a couple of things:
- Move all the code in a src/ folder
- Move bezier.js in the Animated folder
- Rename Animated.js into AnimatedImplementation.js and adds two entry points: AnimatedReactNative.js and AnimatedWeb.js
- Implement very dumb polyfills for flattenStyle, Set and InteractionManager
- Import my work in progress demo.html file to make sure that the code is actually working.

Everything is not working correctly:
- It calls forceUpdate on every frame and doesn't use bindings because setNativeProps is not implemented
- None of the style: {transform} are working because React web doesn't know about the array notation for transform
- The demo need more work

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.
