Error in RNGestureHandlerTouchEvent with react-native-gesture-handler ~2.16.1 on Android

Description

When trying to compile my app using version ~2.16.1 of react-native-gesture-handler, I encounter an error in the init method related to RNGestureHandlerTouchEvent. The error occurs due to an unsafe operation when trying to get the SurfaceId from handler.view. Although I managed to fix the issue by modifying the source code, I believe this should be addressed in the official library.

The build fails with the following error: RNGestureHandlerTouchEvent Type mismatch: inferred type is View! but String was expected

I modified the code in RNGestureHandlerTouchEvent to add null checks in the init method:

private fun <T : GestureHandler<T>> init(handler: T) {
    handler.view?.let { UIManagerHelper.getSurfaceId(it) }
      ?.let { super.init(it, handler.view!!.id) }
    extraData = createEventData(handler)
    coalescingKey = handler.eventCoalescingKey
  }

Steps to reproduce

Create a React Native app with the following setup:
- React Native: 0.75.4
- react-native-gesture-handler: ~2.16.1
- Expo: ^51.0.0
Implement a gesture handler using the RNGestureHandlerTouchEvent function.
Run the project on Android using Android Studio.
