Summary:
Exposing this enum is essentially useless and at worst is a runtime cost that isn't necessary by just using the string.
The value of this enum, as far as I understand it, is to enforce that only valid options are used. We can enforce this at build time with Flow.
I was able to migrate our codebase with a few Find and Replace for things like
```
resizeMode={Image.resizeMode.contain}
```

* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test

Summary:
Issue [#2088](https://github.com/facebook/react-native/issues/2088).
The basic desire is to have a declarative mechanism to transform text content to uppercase or lowercase or titlecase ("capitalized").
My test plan involves having added a test-case to the RNTester app within the `<Text>` component area. I then manually verified that the rendered content met my expectation.
Here is the markup that exercises my enhancement:
```
<View>
<Text style={{ textTransform: 'uppercase'}}>
This text should be uppercased.
</Text>
<Text style={{ textTransform: 'lowercase'}}>
This TEXT SHOULD be lowercased.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
This text should be CAPITALIZED.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
Mixed:{' '}
<Text style={{ textTransform: 'uppercase'}}>
uppercase{' '}
</Text>
<Text style={{ textTransform: 'lowercase'}}>
LoWeRcAsE{' '}
</Text>
<Text style={{ textTransform: 'capitalize'}}>
capitalize each word
</Text>
</Text>
</View>
```

Summary:
On Android, LayoutAnimation directly updates the layout since a generic
scaling animation is more difficult to implement. This causes a problem
if the layout is updated during an animation, as the previous layout is
stored with the animation and is not updated. As a result the view gets
the old layout instead once the animation completes.
This commit fixes this issue by storing the layout handling animations
while those animations are active, and updating the animations on the
fly if one of the views receives a new layout. The resulting behaviour
mirrors what iOS currently does.
This bug has real world consequences, for example if a LayoutAnimation
happens right after a VirtualizedList has mounted, it’s possible that
some list rows are mounted while the animation is active, making the
list content view bigger. If the content view is being animated, the
new size will not take effect and it becomes impossible to scroll to
the end of the list.
I wrote a minimal test case to verify the bug, which I’ve also added to
RNTester. You can find the standalone app here:
<https://gist.github.com/lnikkila/18096c15b2fb99b232795ef59f8fb0cd>
The app creates a 100x300 view that gets animated to 200x300 using
LayoutAnimation. In the middle of that animation, the view’s dimensions
are updated to 300x300.
The expected result (which is currently exhibited by iOS) is that the
view’s dimensions after the animation would be 300x300. On Android the
view keeps the 200x300 dimensions since the animation overrides the
layout update.
The test app could probably be turned into an integration test by
measuring the view through UIManager after the animation, however I
don’t have time to do that right now...

Summary:
A common UI pattern for list empty states is some text/images centered inside the visible part of the list. This is pretty hard to do currently because we wrap ListEmptyComponent with an extra view with no way to style it so we cannot just use `flex: 1` to make it fill the available space.
- Added an example of ListEmptyComponent in the FlatList example in RNTester

Summary:
`<Image resizeMode="repeat" />` for Android, matching the iOS implementation (#7968). (Non-goal: changing the component's API for finer-grained control / feature parity with CSS - this would be nice in the future)
As requested in e.g. #14158.
Given https://github.com/facebook/fresco/issues/1575, and lacking the context to follow the specific recommendations in https://github.com/facebook/fresco/issues/1575#issuecomment-267004303, I've opted for a minimal change within RN itself.
It's likely that performance can be improved by offloading this work to Fresco in some clever way; but I'm assuming that the present naive approach is still an improvement over a userland implementation with `onLayout` and multiple `<Image>` instances.
- Picking up on a TODO note in the existing code, I implemented `MultiPostprocessor` to allow arbitrary chaining of Fresco-compatible postprocessors inside `ReactImageView`.
- Rather than extensively refactor `ImageResizeMode`, `ReactImageManager` and `ReactImageView`, I mostly preserved the existing API that maps `resizeMode` values to [`ScaleType`](http://frescolib.org/javadoc/reference/com/facebook/drawee/drawable/ScalingUtils.ScaleType.html) instances, and simply added a second mapping, to [`TileMode`](https://developer.android.com/reference/android/graphics/Shader.TileMode.html).
- To match the iOS rendering exactly for oversized images, I found that scaling with a custom `ScaleType` was required - a kind of combination of `CENTER_INSIDE` and `FIT_START` which Fresco doesn't provide - so I implemented that as `ScaleTypeStartInside`. (This is, frankly, questionable as the default behaviour on iOS to begin with - but I am aiming for parity here)
- `resizeMode="repeat"` is therefore unpacked by the view manager to the effect of:
```js
view.setScaleType(ScaleTypeStartInside.INSTANCE);
view.setTileMode(Shader.TileMode.REPEAT);
```
And the added postprocessing in the view (in case of a non-`CLAMP` tile mode) consists of waiting for layout, allocating a destination bitmap and painting the source bitmap with the requested tile mode and scale type.
Note that as in https://github.com/facebook/react-native/pull/17398#issue-285235247, I have neither updated nor tested the "Flat" UI implementation - everything compiles but I've taken [this comment](https://github.com/facebook/react-native/issues/12770#issuecomment-294052694) to mean there's no point in trying to wade through it on my own right now; I'm happy to tackle it if given some pointers.
Also, I'm happy to address any code style issues or other feedback; I'm new to this codebase and a very infrequent Android/Java coder.
Tested by enabling the relevant case in RNTester on Android.

Summary:
`letterSpacing` is completely missing from RN Android at the moment.
I've reviewed the `letterSpacing` implementations in #13199, #13877 and #16801 (that all seem to have stalled) and managed to put together an improved one based on #13199, updated to merge cleanly post 6114f863c3, that resolves the [issues](https://github.com/facebook/react-native/pull/13199#issuecomment-354568863) I've identified with that code.
I believe this is the closest PR yet to a correct implementation of this feature, with a few caveats:
- As with the other PRs, this only works on Android >= 5.0 (silently falling back to no letter spacing on older versions). Is this acceptable for a RN feature, in general? Would a dev mode warning be desirable?
- The other PRs seem to have explored the space of potential solutions to the layout issue ([Android renders space _around_ glyphs](https://issuetracker.google.com/issues/37079859), iOS to the _right_ of each one) and come up empty, so I've opted to merely document the difference.
- I have neither updated nor tested the "Flat" UI implementation - everything compiles but I've taken [this comment](https://github.com/facebook/react-native/issues/12770#issuecomment-294052694) to mean there's no point in trying to wade through it on my own right now; I'm happy to tackle it if given some pointers.
- The implementation in `ReactEditText` is only there to handle the placeholder text, as `ReactBaseTextShadowNode` already affects the input control's contents correctly.
- I'm not sure whether `<TextInput>` is meant to respect `allowFontScaling`; I've taken my cue here from `ReactTextInputManager.setFontSize()`, and used the same units (SP) to interpret the value in `ReactEditText.setLetterSpacingPt()`.
- I'm not sure whether `<TextInput>` is even meant to support `letterSpacing` - it doesn't actually work on iOS. I'm not going to be able to handle the Objective-C side of this, not as part of this PR at least.
- I have not added unit tests to `ReactTextTest` - is this desirable? I see that some other props such as `lineHeight` aren't covered there (unless I'm not looking in the right place).
- Overall, I'm new to this codebase, so it's likely I've missed something not mentioned here.

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

Summary:
A demo illustrated `base-line` metric exposure to layout system was added to RNTester.
And currently it shows that we don't support it at all.

Summary:
`<Image resizeMode="center">` already works on iOS (implemented in #8792), but is neither tested nor documented the way the other `resizeMode` values are.
This PR primarily enables the relevant RNTester case on iOS, and secondarily copies over the doc comment from `Image.android.js` to `Image.ios.js`. A PR to `react-native-website` will follow shortly and it is there I will try and revise the wording a bit.
Updated RNTester screenshot (iOS):

Summary:
This is a complete rewrite of RCTText, the part of React Native which manages Text and TextInput components.
Key points:
* It's understandable now. It follows a simple architectural pattern, and it's easy to debug and iterate. Text flow layout is a first-class citizen in React Native layout system now, not just a wired special case. It also brings entirely new possibilities such as nested interleaving <Text> and <View> components.
* All <Text>-specific APIs were removed from UIManager and co (it's about ~16 public methods which were used exclusively only by <Text>).
* It relies on new Yoga measurement/cloning API and on-dirty handler. So, it removes built-in dirty propagation subsystem from RN completely.
* It caches string fragments properly and granularly on a per-node basis which makes updating text-containing components more performant.
* It does not instantiate UIView for virtual components which reduces memory utilization.
* It drastically improves <TextInput> capabilities (e.g. rich text inside single line <TextInput> is now supported).

Summary:
Builds off of cae7179c94
- Make the prop a dictionary for more configuration options
- Rename `maintainPositionAtOrBeyondIndex` -> `maintainVisibleContentPosition` + `minIndexForVisible`
- Add autoscroll threshold feature
Given the async native of RN JS and background layout, there is no way to trigger the scrollTo from JS without risking a delay, so we add the feature in native code.

Summary:
== Problem / Background ==
Most lists paginate in a single direction (standard infinite list), but some paginate in both directions. Most common example is a chat thread where new messages show up on the bottom, and old content can be loaded by scrolling up. Comment threads are another example.
Right now, adding content to the bottom of a scroll view is smooth - the content doesn't jump. But when adding to the top of the scrollview, the content gets pushed down, which is jarring (note this may appear reversed because of inverting the list which is common for chat applications).
== Approach ==
The basic idea is simple - we set a flag in JS, then for every uimanager transaction, we record which is the first eligible and visible view in the ScrollView, and compare it's new origin to the old one. If it has changed, we update the contentOffset of the ScrollView to compensate.
This is done by observing `willPerformMounting` directly (only from scrollviews that have this new property set), and then observing the prev state with prependUIBlock and making the update synchronously in addUIBlock to avoid any flicker.
There is also a way to skip views that we don't care about, like a spinner at the top of the view that we don't want to stay in place - we actually want it to get pushed up by the new content, replaced visually in the viewport.
== Notes ==
Most chat applications will probably want to do a scrollToTop when new content comes in and the user is already scrolled at or near the bottom.
This is glitchy if visible children are re-ordered, which could be fixed with additional logic, but it doesn't come up in the type of applications we're targetting here so punting on that.

Summary:
This implements onKeyPress for Android on TextInputs and addresses https://github.com/facebook/react-native/issues/1882.
**N.B. that this PR has not yet addressed hardware keyboard inputs**, but doing will be fairly trivial. The main challenge was doing this for soft keyboard inputs.
I've tried to match the style as much as I could. Will happily make any suggested edits be they architectural or stylistic design (edit: and of course implementation), but hopefully this is a good first pass :).
I think important to test this on the most popular keyboard types; maybe different languages too.
I have not yet added tests to test implementation, but will be happy to do that also.
- Build & run RNTester project for Android and open TextInput.
- Enter keys into 'event handling' TextInput.
- Verify that keys you enter appear in onKeyPress below the text input
- Test with autocorrect off, on same input and validate that results are the same.
Below is a gif of PR in action.
