Summary: We construct this from JNI, which doesn't care about visibility, and then only want to expose `StateWrapper` as the public interface. Changelog: [Android][Removed] - Make StateWrapperImpl Internal Reviewed By: Abbondanzo Differential Revision: D73161592
Summary: This adds the ability to represent Fabric State sent to Java View managers as a raw JNI reference. This is used by Facsimile to tell a component to mount a layout, previously generated during measurement. This API is consciously well hidden (in comparison to MapBuffer which is fairly public). To use it: 1. The concrete state data representation must implement a method named `getJNIReference()` that returns an fbjni ref 2. The Java view manager must cast the `StateWrapper` to an internal `ReferenceStateWrapper` type, not exposed outside of React Native internals Changelog: [Internal] Reviewed By: alanleedev Differential Revision: D73159146
Summary: This forms the basis for a replacement of `TextView`. This started off with Litho's [`RCTextView`](https://github.com/facebook/litho/blob/master/litho-rendercore-text/src/main/java/com/facebook/rendercore/text/RCTextView.java), which is a simple view, for rendering a text layout, and providing some built-in keyboard navigation and a11y support. Many changes were made to it, including: 1. Removing many parts not relevant to RN, or which will be replaced by other RN infra. E.g. we will reuse existing a11y delegates, have existing ways of creating Spannables and text layouts, inline views, etc 2. Converting to Kotlin 3. Adding back in some changes required for RN's drawing, and expected view manager APIs (e.g. overflow/clipping customization) 4. Making it target a ViewGroup instead of a View, for correct inline view support down the line Because we rely on drawing text layout, with the same Spannable as before, most things "just work", because they are part of the layout we are drawing, generated by TextLayoutManager on the Fabric side. We don't offer much customization to what can be drawn, forcing it to have happened in the layout we are showing already. There are quite a few bits not implemented yet. Some of these are cases, like `textAlignVertical`, were previously incorrectly implemented just at the ReactTextView layer, so Fabric layout was unaware of them. Another similar class to this is any non-default fonts which we must load. `adjustsFontSizeToFit` (stubbed out in later diff) will also need some tweaking with the new assumption we don’t want to mutate Spans/layouts set in State. Fine grained selection support is the largest tbd. Changelog: [Internal] Reviewed By: Abbondanzo Differential Revision: D73282649
Summary: This implements the view manager for `PreparedLayoutTextView`, originating by taking the view managers composing `ReactTextView`, converting to Kotlin, and removing everything no longer needed. In Facsimile, anything influencing text appearance is applied earlier, when creating the Fabric layout, so there are many less setters here. Most visual attributes are instead present in the state we are presenting. We have tasks for some of these, that need to be reimplemented, as they do not currently influence the Spannable being measured. That includes e.g. `ReactTextViewManagerCallback`, used for injection, and `dataDetectorType` for linkifying Spannable. Changelog: [Internal] Reviewed By: rshest Differential Revision: D73287706
