Google Maps onCameraIdle not working in iOS when in a Stack. #33988
Description
Steps to Reproduce
I have a layout where in a Stack I have a GoogleMap, a GestureDetector on top of it that currently absorbs all the taps and doesn't pass it to the GoogleMap. Once tapped, GestureDetector allows the taps to be passed onto GoogleMap.
Problem is, whenever I make this kind of layout, the onCameraIdle callback is not being called in iOS (works in Android). Double tapping the map or tapping on a marker somehow resets the callback, but it doesn't work the first time.
class FancyMapPageState extends State<FancyMapPage> {
...
@override
Widget build(BuildContext context) {
return Stack(
children: <Widget>[
GoogleMap(
...
),
GestureDetector(
behavior: !_animationController.isCompleted
? HitTestBehavior.opaque
: HitTestBehavior.deferToChild,
onTap: () {
_animationController.forward();
},
),
SlideTransition(
position: _cardSlideAnimation,
Container(
child: ...,
),
),
],
);
}
}
