Flutter has code of the form

typedef void GestureTapCancelCallback();
GestureTapCancelCallback onTapCancel;
T invokeCallback<T>(String name, RecognizerCallback<T> callback, { String debugReport() }) {
}
main() {
  invokeCallback<Null>('spontaneous onTapCancel', onTapCancel);
}

which leads to runtime errors in strong mode.

All this code needs to be converted to use

(please see issue #31858 for more details).

Now that @crelier has fixed the vm parser to support 'void' generic arguments we should be ok converting
the flutter code to use this (see issue #30516 )

This may require some progress on #30177 , in that if you try to land code that uses void as a type argument you get analyzer errors until support lands.
