the map goes crazy when i zoom

[Ricardo Montoya Lopez]

Hello everyone, I'm having problems with sfmaps, what happens is that when I zoom in and zoom out if I scroll the screen while the map is loading, the map gets out of control and jumps to a distant location. I have tried many things but I have not been able to solve this error, I even tried to use onWillZoom to deactivate the panning, wait for the map to finish loading and reactivate the panning but still the error continues. Does anyone have any idea what is going on and how I can fix it?, the problem is in android

here is my code:

import 'package:flutter/material.dart';

import 'package:syncfusion_flutter_maps/maps.dart';

void main() {

return runApp(MapsApp());

}

/// This widget will be the root of application.

class MapsApp extends StatelessWidget {

@override

Widget build(BuildContext context) {

return const MaterialApp(

title: 'Maps Demo',

home: MyHomePage(),

);

}

}

/// This widget is the home page of the application.

class MyHomePage extends StatefulWidget {

/// Initialize the instance of the [MyHomePage] class.

const MyHomePage({Key? key}) : super(key: key);

@override

State<MyHomePage> createState() => _MyHomePageState();

}

class _MyHomePageState extends State<MyHomePage> {

_MyHomePageState();

bool _onZoom = false;

late MapTileLayerController _mapController;

late MapZoomPanBehavior _zoomPanBehavior;

@override

void recurrentPanningControl() async{

if ( _onZoom ){

print('Esperando reconstrucción del mapa');

await Future.delayed(const Duration(seconds: 2));

_zoomPanBehavior.enablePanning = true;

_onZoom = false;

setState(() {});

recurrentPanningControl();

} else{

print('Ejecutando');

await Future.delayed(const Duration(milliseconds: 100));

recurrentPanningControl();

}

}

@override

void initState() {

super.initState();

_mapController = MapTileLayerController();

_zoomPanBehavior = MapZoomPanBehavior(

//enablePanning: false,

//enablePinching: false,

zoomLevel: 13,

minZoomLevel: 3,

maxZoomLevel: 19,

focalLatLng: const MapLatLng(6.263208604725203, -75.57770846194757),

enableDoubleTapZooming: true,

toolbarSettings: const MapToolbarSettings(direction: Axis.vertical)

);

Future.delayed(const Duration(seconds: 0), () async {

recurrentPanningControl();

});

}

@override

Widget build(BuildContext context) {

return Scaffold(

body: SizedBox(

height: double.infinity,

width: double.infinity,

child: Center(

child: SfMaps(

layers: <MapLayer>[

MapTileLayer(

urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png',

zoomPanBehavior: _zoomPanBehavior,

controller: _mapController,

tooltipSettings: const MapTooltipSettings(color: Colors.transparent),

onWillZoom: (MapZoomDetails map){

_zoomPanBehavior.enablePanning = false;

_onZoom = true;

return true;

},

),

],

),

),

),

);

}

}
