GoogleMaps and GestureDetector don't play well together #59433
Description
In my app I have a GoogleMap widget that is the child of a GestureDetector widget.
I need to set a variable every time the user moves the map (pan, scale, etc) and I'm using the GestureDetector for that. Also, I need the map to simultaneously receive the gestures, in order the be interactive.
My code kind of works, but it is not responsible or reliable on scale (pinch) gestures. Sometimes the events are handled by the map and other times they aren't. Pan events (drag with one finger) are handled just fine.
Any idea on that is causing this behavior?
Here is the code...
return Scaffold(
body: GestureDetector(
onPanStart: (val) {
Logger.red("Parent: I'm panning...");
_followPosition = false;
},
behavior: HitTestBehavior.opaque,
child: GoogleMap(
gestureRecognizers: [
Factory<PanGestureRecognizer>(() => PanGestureRecognizer()),
Factory<ScaleGestureRecognizer>(() => ScaleGestureRecognizer()),
].toSet(),
initialCameraPosition: _cameraPosition,
onMapCreated: (GoogleMapController controller) =>
_handleMapCreated(controller),
onCameraMove: (CameraPosition cameraPosition) =>
_handleCameraMove(cameraPosition),
onCameraIdle: () => _handleCameraIdle(),
),
),
);
