Why
Fixes #3368 which is my regression from #3352
How
JSModule
registerCallableModule()
does not support multiple listeners. The newer WebView will overwrite the previously registered callbacks.This PR tries to move
registerCallableModule()
at top as a module singleton. With an intermediate EventEmitter to dispatch events to each WebViews. I tries to import the internal vendored EventEmitter from react-native. If that is not ideal, we could replace as third-party EventEmitter such as fbemitter.Test Plan
extend the Messsaging.tsx example as two WebViews and check whether messages are sent correctly.
