I have gestureRecognizers parameter set like this:
child: GoogleMap(
initialCameraPosition: widget.cameraPosition!,
gestureRecognizers: <Factory<OneSequenceGestureRecognizer>>[
new Factory<OneSequenceGestureRecognizer>(
() => new EagerGestureRecognizer(),
),
].toSet(),
but it's allowing to scroll maps only with one finger, but I want it possible only with two? I heard it's possible but how?
Look here: https://gist.github.com/awaik/7d5b6d6ec644ae844a3740dddc990ed4
it's a sample app with implementation of two finger swipe:
class SwipeDemo extends StatefulWidget {
const SwipeDemo({Key? key}) : super(key: key);
@override
SwipeDemoState createState() => SwipeDemoState();
}
class SwipeDemoState extends State<SwipeDemo> {
Offset offset = Offset.zero;
@override
Widget build(BuildContext context) {
return SafeArea(
child: TwoFingerPointerWidget(
onUpdate: (details) {
setState(() {
offset += details.delta;
});
},
child: Container(
alignment: Alignment.center,
color: Colors.white,
child: Transform.translate(
offset: offset,
child: Container(
width: 100,
height: 100,
color: Colors.red,
),
),
),
),
);
}
}
