Summary:
This adds support for `adjustsFontSizeToFit` and `minimumFontScale` on Android. The implementation tries to match closely the behaviour on iOS (hardcoded 4px min size for example). It uses a simpler linear algorithm for now, opened to improving it now if it is a deal breaker or in a follow up.
See https://twitter.com/janicduplessis/status/1171147709979516929 for a more detailed thread about the implementation
## Changelog
[Android] [Added] - Implement `adjustsFontSizeToFit` on Android
Pull Request resolved: https://github.com/facebook/react-native/pull/26389
Test Plan: Tested by adding the existing `adjustsFontSizeToFit` example from the iOS text page to android. Also added a case for limiting size by using `maxHeight` instead of `numberOfLines`.

Launches a new implementation of `TouchableNativeFeedback`.
It is implemented using `Pressability` and extends `React.Component`. Notably, `propTypes` no longer exist.
Furthermore, `TouchableNativeFeedback` now behaves similar to `TouchableWithoutFeedback` on iOS (instead of rendering an error message).

Summary:
Changing PanResponderExample to use React state instead of setNativeProps. Fabric likely won't have setNativeProps so this is a conversion in that direction. This is probably one of the most complicated usages of setNativeProps and it feels *okay* with React state. I'm sure it is worse on lower end devices though.
In general we know that going to JS for an animation is not the correct approach so this getting worse in Fabric is probably fine for that reason too. Staying in native with something like react-native-gesture-handler is probably more aligned with the future.

Summary:
We found that many callsites existed that could be using the native driver, but weren't. In order to help people use it when appropriate and eventually switch the default, we are requiring that useNativeDriver is explicit, even when set to false.
This change adds a runtime warning if useNativeDriver is not specified, hopefully giving some light feedback to remember to use the native driver when you can. Without it being explicit it is very easy to forget setting this.

Summary:
When using a medium (500) font weight on Android the wrong weight is used for the placeholder and for the first few seconds of input (before it gets text back from JS). To fix it I refactored the way we handle text styles (family, weight, style) to create a typeface to be more like the `Text` component.
Since all these 3 props are linked and used to create the typeface object it makes more sense to do it at the end of setting props instead of in each prop handler and trying to recreate the object without losing styles set by other prop handlers. Do do that we now store fontFamily, fontStyle and fontWeight as ivar of the ReactEditText class. At the end of updating prop if any of those changed we recreate the typeface object.
This doesn't actually fix the bug but was a first step towards it. There were a bunch of TODOs in the code to remove duplication between `Text` and `TextInput` for parsing and creating the typeface object. To do that I simply moved the code to util functions in a static class. Once the duplication was removed the bug was fixed! I assume proper support for medium font weights was added for `Text` but not in the duplicated code for `TextInput`.

Summary:
React Native components need a mechanism to specify their value to assistive technologies. This PR adds the notion of accessibilityValueDescription-- a property which either contains a textual description of a component's value, or for range-based components, such as sliders and progress bars, it contains range information (minimum, current, and maximum).
On iOS, the range-based info if present is converted into a percentage and added to the accessibilityValue property of the UIView. If text is present as part of the accessibilityValueDescription, it is used instead of the range-based information.
On Android, any range-based information in accessibilityValueDescription is exposed in the AccessibilityNodeInfo's RangeInfo. Text which is part of accessibilityValueDescription is appended to the content description.

Summary:
I wanted to configure the RN dev menu without having to write native code. This is pretty useful in a greenfield app since it avoids having to write a custom native module for both platforms (and might enable the feature for expo too).
This ended up a bit more involved than planned since callbacks can only be called once. I needed to convert the `DevSettings` module to a `NativeEventEmitter` and use events when buttons are clicked. This means creating a JS wrapper for it. Currently it does not export all methods, they can be added in follow ups as needed.

Summary:
Initial conversion of RNTester to support light and dark themes. Theming is implemented by providing the desired color theme via context. Example:
```
const ThemedContainer = props => (
<RNTesterThemeContext.Consumer>
{theme => {
return (
<View
style={{
paddingHorizontal: 8,
paddingVertical: 16,
backgroundColor: theme.SystemBackgroundColor,
}}>
{props.children}
</View>
);
}}
</RNTesterThemeContext.Consumer>
);
```
As RNTester's design follows the base iOS system appearance, I've chosen light and dark themes based on the actual iOS 13 semantic colors. The themes are RNTester-specific, however, and we'd expect individual apps to build their own color palettes.
## Examples
The new Appearance Examples screen demonstrates how context can be used to force a theme. It also displays the list of colors in each RNTester theme.
https://pxl.cl/HmzW (screenshot: Appearance Examples screen on RNTester with Dark Mode enabled. Displays useColorScheme hook, and context examples.)
https://pxl.cl/HmB3 (screenshot: Same screen, with light and dark RNTester themes visible)
Theming support in this diff mostly focused on the main screen and the Dark Mode examples screen. This required updating the components used by most of the examples, as you can see in this Image example:
https://pxl.cl/H0Hv (screenshot: Image Examples screen in Dark Mode theme)
Note that I have yet to go through every single example screen to update it. There's individual cases, such as the FlatList example screen, that are not fully converted to use a dark theme when appropriate. This can be taken care later as it's non-blocking.

Summary:
In order to cleanup the callsites that are not using Animated's native driver, we are going to make useNativeDriver a required option so people have to think about whether they want the native driver or not.
I made this change by changing [Animated.js](https://fburl.com/ritcebri) to have this animation config type:
```
export type AnimationConfig = {
isInteraction?: boolean,
useNativeDriver: true,
onComplete?: ?EndCallback,
iterations?: number,
};
```
This causes Flow to error anywhere where useNativeDriver isn't set or where it is set to false.
I then used these Flow errors to codemod the callsites.
I got the location of the Flow errors by running:
```
flow status --strip-root --json --message-width=0 | jq '.errors | [.[].extra | .[].message | .[].loc | objects | {source: .source, start: .start, end: .end}]'
```
And then ran this codemod:
```
const json = JSON.parse('JSON RESULT FROM FLOW');
const fileLookup = new Map();
json.forEach(item => {
if (!fileLookup.has(item.source)) {
fileLookup.set(item.source, []);
}
fileLookup.get(item.source).push(item);
});
export default function transformer(file, api) {
const j = api.jscodeshift;
const filePath = file.path;
if (!fileLookup.has(filePath)) {
return;
}
const locationInfo = fileLookup.get(filePath);
return j(file.source)
.find(j.ObjectExpression)
.forEach(path => {
if (
path.node.properties.some(
property =>
property != null &&
property.key != null &&
property.key.name === 'useNativeDriver',
)
) {
return;
}
const hasErrorOnLine = locationInfo.some(
singleLocationInfo =>
singleLocationInfo.start.line === path.node.loc.start.line &&
Math.abs(
singleLocationInfo.start.column - path.node.loc.start.column,
) <= 2,
);
if (!hasErrorOnLine) {
return;
}
path.node.properties.push(
j.property(
'init',
j.identifier('useNativeDriver'),
j.booleanLiteral(false),
),
);
})
.toSource();
}
export const parser = 'flow';
