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!
✨ Done in 23.60s.

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.
[IOS] [ENHANCEMENT] [NativeAnimated] - Allow `shadowRadius` and `shadowOpacity` as NativeAnimated style properties.

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,
}
// ...
}
```
Unnecessary for cosmetic change.

Summary:
Fixes the error `Trying to update interpolation node that has not been
attached to the parent` in android which occurs when using multiple
Animated.Values along with interpolation and an animation is run before
another one that uses interpolation. On ios, no error is thrown in such
case but the animation also doesn't work as expected.
You can check the snack code here which works properly without
useNativeDriver: true. But fails on android and skips the first stage
of animation on ios.

**Test Plan**
The animations worked properly after the __makeNative override made
the parent node native as well.

Summary:
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. Also since we are not passing certain props because they are driven by native it is possible that the view will be marked as layout only when in fact it is not.
**Test plan**
Animated a simple view that will be collapsed with native animated and reproduce the error (it's actually just an error log in logcat now and no longer a redscreen) and checked that this fixes it.

Summary:
There was some missing super.__detach calls in some Animated nodes, we rely on the base class being called to drop the node in the native implementation, not doing so will cause some nodes to leak. It also resulted in a crash when removing certain nodes because they would get updated after being detached.
**Test plan**
Reproduced the crash by unmounting a view that uses a DiffClamp node and made sure this fixes it. Also tested that other native animations still worked properly.

Delay was broken with native animations on iOS. After checking what android does to handle delay, I noticed it does nothing at all since the delay is already handled when generating the animation frames. This removes all code that tried to handle delay on iOS since it is not needed and breaks it. Also updated an example to have delay in UI explorer.

Summary:
Need to make sure `detach` happens on the old `scrollableNode` before it's unmounted and that `attach` happens on the new `scrollableNode` after it's mounted. This should also be more performant because the detach step no longer requires iterating through all the props, most of which are not animated, and we filter out unneeded updates if props or ref haven't changed.

Hook up native onscroll events in `FlatListExample` and toggle "debug" - before, the events would stop working because they would try to attach to the old unmounted node, but with this diff it keeps working as expected.

Summary:
* Any animation can be looped on the javascript thread
* Only basic animations supported natively at this stage, loops run
using the native driver cannot contain animations of type sequence,
parallel, stagger, or loop
Motivation: We need a spinner in our app that is displayed and animated while the javascript thread is tied up with other tasks. This means it needs to be offloaded from the javascript thread, so that it will continue to run while those tasks are churning away.
I originally submitted PR #9513, which has served our needs, but brentvatne pointed out a better way to do it. Had hoped his suggestion would be implemented by janicduplessis or another fb employee, but after 5 months I thought I'd give it another push.
I've put together an implementation that basically matches the suggested API. Let me know what you think, and whether others can pick it up from here and get it in to core.

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.

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`.
TODO:
- Need to check why momentum scrolling isn't triggering scroll events properly on Android.
- Remove native iOS implementation
- cleanup / fix flow
