    Called either when the host activity receives a resume event (e.g. onResume orif the native module that implements this is initialized while the host activity is alreadyresumed. Always called for the most current activity.
  - onHostPause
```
 void onHostPause()
```
    Called when host activity receives pause event (e.g. onPause. Always calledfor the most current activity.
  - onHostDestroy
```
 void onHostDestroy()
```
    Called when host activity receives destroy event (e.g. onDestroy. Only calledfor the last React activity to be destroyed.

    The CatalystInstance is going away with Venice. Therefore, the TurboModule infra introduces theinvalidate() method to allow NativeModules to clean up after themselves.
