Summary:
TextInlineViews in Android was incorrectly converting values to from float to int, this produced to loose precision and to render incomplete texts in some components.
This diff changed the types from int to float, avoiding loose precision.
The impact of this bug is not that high because in the conversion to int we were using Math.ceil(), which was already rounding the result to the next pixel.

Summary:
When text is in a constrained parent view using `maxWidth`, long text may wrap. When the text wraps, the final width is dependent on the word breaking strategy and text content. This means that the text width is not necessarily `maxWidth`.
However, the current way that we compute text layout does not shrinkwrap the text width as much as possible. This leads to visual gaps to the end-side of wrapped text.
This changes the text layout slightly so that we use the length of the longest line.
This bug only exists on Android. After this change, Android behaves like iOS.

Summary:

The root cause of the bug is that we were parsing the props of the text using the TextAttributeProps class, this is incorrect because TextAttributeProps is a holder of the C++ TextAttributes and not TextProps, but the name is confusing.
As a consecuence there was some mistmaches of types during parsing and that was throwing an exception in some examples.

Summary:
This Pull Request implements the PlatformColor proposal discussed at https://github.com/react-native-community/discussions-and-proposals/issues/126. The changes include implementations for iOS and Android as well as a PlatformColorExample page in RNTester.
Every native platform has the concept of system defined colors. Instead of specifying a concrete color value the app developer can choose a system color that varies in appearance depending on a system theme settings such Light or Dark mode, accessibility settings such as a High Contrast mode, and even its context within the app such as the traits of a containing view or window.
The proposal is to add true platform color support to react-native by extending the Flow type `ColorValue` with platform specific color type information for each platform and to provide a convenience function, `PlatformColor()`, for instantiating platform specific ColorValue objects.
`PlatformColor(name [, name ...])` where `name` is a system color name on a given platform. If `name` does not resolve to a color for any reason, the next `name` in the argument list will be resolved and so on. If none of the names resolve, a RedBox error occurs. This allows a latest platform color to be used, but if running on an older platform it will fallback to a previous version.
The function returns a `ColorValue`.
On iOS the values of `name` is one of the iOS [UI Element](https://developer.apple.com/documentation/uikit/uicolor/ui_element_colors) or [Standard Color](https://developer.apple.com/documentation/uikit/uicolor/standard_colors) names such as `labelColor` or `systemFillColor`.
On Android the `name` values are the same [app resource](https://developer.android.com/guide/topics/resources/providing-resources) path strings that can be expressed in XML:
XML Resource:
`@ [<package_name>:]<resource_type>/<resource_name>`
Style reference from current theme:
`?[<package_name>:][<resource_type>/]<resource_name>`
For example:
- `?android:colorError`
- `?android:attr/colorError`
- `?attr/colorPrimary`
- `?colorPrimaryDark`
- `android:color/holo_purple`
- `color/catalyst_redbox_background`
On iOS another type of system dynamic color can be created using the `IOSDynamicColor({dark: <color>, light:<color>})` method. The arguments are a tuple containing custom colors for light and dark themes. Such dynamic colors are useful for branding colors or other app specific colors that still respond automatically to system setting changes.
Example: `<View style={{ backgroundColor: IOSDynamicColor({light: 'black', dark: 'white'}) }}/>`
Other platforms could create platform specific functions similar to `IOSDynamicColor` per the needs of those platforms. For example, macOS has a similar dynamic color type that could be implemented via a `MacDynamicColor`. On Windows custom brushes that tint or otherwise modify a system brush could be created using a platform specific method.
## Changelog

Summary:
When the TextInput is updated on the Java side, make sure C++ State gets updated. We do this by making sure that the AttributedString data-structured in mirrored in Java and in C++.
In practice, the AttributedString is copied into Java a few times during initialization, and then after then, 99% of the time Java is writing without receiving updates from C++. This means that we should optimize the Java-to-C++ update path most aggressively in the future.
However, it turns out that for now, at least, we can't reuse NativeWritableMaps/NativeWritableArrays because they're consumed on the C++ side and can't be modified after that. This is a perf improvement for the future.
This allows us the user to edit any fragments, and the changes will flow through C++ State. This also allows us to edit across multiple Fragments.

Summary: This diff fixes the issue with view paddings in Fabric introduced in D17081799. In Paper setting padding on a view was only supported for Text and TextInput components (see https://fburl.com/codesearch/6r6lu5vd). We want to keep Fabric backwards compatible, so we delegate setting the padding to the view manager instead of setting it directly on the view. In this way we can have a no-op implementation in the base view manager and implement this method only in view managers that support setting padding (ReactTextInputManager and ReactTextViewManager at the moment).

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:
[Android] [Fixed] - Use HYPHENATION_FREQUENCY_NONE instead of HYPHENATION_FREQUENCY_NORMAL to measure text
The text must be measured with HYPHENATION_FREQUENCY_NONE instead of HYPHENATION_FREQUENCY_NORMAL, since ReactTextView has hyphenation frequency set to HYPHENATION_FREQUENCY_NONE. These two values must match, otherwise the measured height of text we return from the Yoga measure function might be wrong.
Even though the TextView [documentation](https://developer.android.com/reference/android/widget/TextView#setHyphenationFrequency(int)) says that the default hyphenation frequency is HYPHENATION_FREQUENCY_NORMAL before Android Q, it's not true for TextViews instantiated in code (the default value is set from the theme which is missing in case of ReactTextView).
See the screenshots below where the text is measured incorrectly which causes the last line to be cut off.
I extracted the value to a class member variable because I'm planning to expose the hyphenationFrequency prop for the Text component so that it can be configured on Android (as requested by this Github issue: https://github.com/facebook/react-native/issues/17199).
