  2. Notice the background colour was appropriately applied to the View defined in line 27
  3. Uncomment line 25 (StatusBar.backgroundColor)

Research direction

Start with the linked InvariantStatusBar reproducer and run it with npm run android on a Material You device or emulator. Trace StatusBar._updatePropsStack while PlatformColor is passed as backgroundColor; done means the platform color is accepted without the invariant error and the status bar background is applied.
