Steps to Reproduce

1. Add GoogleMap under an ExcludeSemantics component.
2. Run flutter on Android
3. Start TalkBack
4. Tap google map

Expected results:

TalkBack should not select the Google Map widget.

Actual results:

Notice that on tap, Google Map can still be selected by TalkBack, and TalkBack announces "Google Map, tap twice to activate". Tapping twice does nothing.

ExcludeSemantics(
    child: GoogleMap(
        ...
    ),
);
