Introducing Timeline: A time-travel debugging tool (cross-platform part)

336876509c Introducing Timeline: A time-travel debugging tool (cross-platform part)

The TimelineController is a C++ class friend of the UIManager class which allows you to rewind the series of UIManager commits with the TimelineHandler class.

Remember that the UIManager makes commits to update how the UI looks.

These classes will likely be used in a near future with a debugging tool to allow you to time travel UI updates similar to how Redux can time travel state updates.

This is a core part of the Timeline feature (aka Time Travel Debugger). With these new primitives, any external library can initiate “saving” all the previous interface changes (commits) and unwind to any previous one (in order to introspect and validate visual side-effects).

+ * Provides tools for introspecting the series of commits and associated
+ * side-effects, allowing to "rewind" UI to any particular commit from the past.

When there are multiple sticky headers, ScrollViewStickyHeader should push up the header above it when it gets to the top. This behavior was accidentally changed in D21948830 (https://github.com/facebook/react-native/commit/fa5d3fb6b8c561b749f3e86316d06543a52dcc1c) when this component was fixed to work in Fabric.
