Stub

canOverrideExistingModule

open override fun canOverrideExistingModule(): Boolean

Return true if you intend to override some other native module that was registered e.g. as part of a different package (such as the core one). Trying to override without returning true from this method is considered an error and will throw an exception during initialization. By default all modules return false.

Sends an event to the JS instance that the preferred color scheme has changed.
