Vladislav Pilgasov 4906f8d28c Add an implementation of Animated.subtract
Summary:
Fixes #18451

I've added another example to NativeAnimationsExample, which makes use of `Animated.substract()`, let me know if the example is not desired / doesn't add much value. Below two GIFs of the new method working on iOS and Android:

Krzysztof Magiera b48f7e5605 Support for animated tracking in native driver
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

[GENERAL][FEATURE][Native Animated] - Added support for animated tracking to native driver. Now you can use `useNativeDriver` flag with animations that track other Animated.Values

Janic Duplessis c47759a9ae Fix potential retain cycles in Animated iOS
Summary:
Fixes potential retain cycles detected by an internal fb tool.

```
First:

__NSDictionaryM
-> RCTPropsAnimatedNode
-> _parentNodes -> __NSDictionaryM
-> RCTStyleAnimatedNode
-> _childNodes -> __NSDictionaryM

Second:

RCTScrollView
-> _eventDispatcher -> RCTEventDispatcher
-> _observers -> __NSArrayM
-> RCTNativeAnimatedModule
-> _nodesManager -> RCTNativeAnimatedNodesManager
-> _uiManager -> RCTUIManager
-> _viewRegistry -> __NSDictionaryM
-> RCTScrollView
```

First fix:
Use weak map for parent and child nodes, strong refs are managed by RCTNativeAnimatedNodesManager

Second fix:
Make RCTEventDispatcher observers a weak array and make sure we don't keep strong refs to UIManager in RCTNativeAnimatedNodesManager and RCTPropsAnimatedNode.

Tested that native animations still work in UIExplorer

Krzysztof Magiera b8fafb46c1 Stop native driver animations when value is set.
Summary:
This diff changes the behaviour of natively driven animations in case the node that they are being run for has its value changed using `setValue` or as a result of an incoming event.

The reason for changing that is to match the JS implementation of `setValue` which behaves as described above (see relevant code here: 7cdd4d48c8/Libraries/Animated/src/AnimatedImplementation.js (L743))

**Test Plan:**
Use this sample app: https://snack.expo.io/B1V7RX9r-
Change: `USE_NATIVE_DRIVER` const between `true` and `false`.
See the animation stops regardless of the state of `USE_NATIVE_DRIVER` unlike before when it would stop only when `USE_NATIVE_DRIVER` was set to `false`

Janic Duplessis fc45471af2 Native Animations - Fix edge case with restore default values
Summary:
There was an edge case where sometimes a view could be added and removed in the same batch so this caused issues because we ran `disconnectAnimatedNodeFromView` before `connectAnimatedNodeToView`. This separates restoring default values from `disconnectAnimatedNodeFromView` so we can run only `restoreDefaultValues` on the pre-operations queue and just do nothing in case the view doesn't exist (it is fine because we know it will be removed immediately).

**Test plan**
Tested that native animations still work properly in RNTester and tested that the edge case crash was fixed.

Janic Duplessis 1d37dd063c Native Animated - Add tests on iOS
Summary:
Adds unit tests to the Native Animated implementation on iOS. This pretty much mirrors the tests we currently have on Android.

It also fixes 2 bugs I've found when adding the tests and pass the current time in `stepAnimation` instead of using `CACurrentMediaTime` to make testing easier.

- `stopListeningToAnimatedNodeValue` did not actually work at all, it should set the listener to nil.
- The finished value in the animation end callback was always true, this simplifies the `RCTAnimationDriver` interface to get rid of `removeAnimation` and fixes the end callback value.

**Test plan**
- Run the tests
- Make sure the UIExplorer example still works

Janic Duplessis 921b9ac53d Native Animated - Support multiple events attached to the same prop
Summary:
Re-applying the diff that was reverted in D4659669 / b87f4abf78 because of some crashes with fixes from D4659708 merged in.

 ---

Fixes a bug that happens when trying to use ScrollView with sticky headers and native `Animated.event` with `onScroll`. Made a few changes to the ListViewPaging UIExplorer example to repro https://gist.github.com/janicduplessis/17e2fcd99c6ea49ced2954d881011b09.

What happens is we need to be able to add multiple events to the same prop + viewTag pair. To do that I simple changed the data structure to `Map<prop+viewTag, List<AnimatedEventDriver>>` and try to optimize for the case where there is only one item in the list since it will be the case 99% of the time.

**Test plan**
Tested by reproducing the bug with the above gist and made sure it was fixed after applying this diff.

Ryan Gomba c858420b2d Fix NativeAnimation invalidation & races on iOS
Summary:
This diff attempts to fix a number of iOS native animation bugs related to improper node invalidation and a race with view creation. The major issues were presented in #9120 as problems 3 and 3b, but I'll recap here:

The invalidation model we use is overly complicated and incomplete. The proper combination of `_needsUpdate` and `_hasUpdated` will result in nodes values being recomputed. However, we do not invalidate nodes in all the places we should, e.g. if we create a new view and attach it to an existing value node (see example in #9120). This diff chooses to remove the `_hasUpdated` flag, and simply relies on the `_needsUpdate` flag to mark a node as dirty.

We mark nodes as dirty when they are:
- created
- updated
- attached to new parents
- detached from old parents
- attached to a view

Calling `updateNodeIfNecessary` will, if necessary, compute all invalidated parent values before recomputing the node value. It will then apply the update, and mark the no
