Your question
Using Geolocator.getPositionStream with MapLibre_gl causes frame refreshes on Android, even when the GPS coordinates are not changing. This behavior, observed on Android but not iOS, leads to constant frame generation.
Versions:
- geolocator: 14.0.1
- maplibre_gl: 0.22.0
Sample code to reproduce the issue:
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:geolocator/geolocator.dart';
import 'package:maplibre_gl/maplibre_gl.dart';
class TestGeolocator extends StatefulWidget {
const TestGeolocator({super.key});
@override
State<TestGeolocator> createState() => _TestGeolocatorState();
}
class _TestGeolocatorState extends State<TestGeolocator> {
@override
void initState() {
super.initState();
WidgetsBinding.instance.addPostFrameCallback((_) async {
await _trackCoordinates();
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: MapLibreMap(
compassViewPosition: CompassViewPosition.topRight,
styleString: 'https://style_url',
myLocationEnabled: true,
initialCameraPosition: const CameraPosition(
target: LatLng(40.947970551634754, -4.118041773948952),
zoom: 18.5,
),
trackCameraPosition: true,
),
),
);
}
Future<void> _trackCoordinates() async {
var locationSettings = const LocationSettings(accuracy: LocationAccuracy.high, distanceFilter: 5);
Geolocator.getPositionStream(locationSettings: locationSettings).listen((position) async {
print('${position.latitude}, ${position.longitude}');
});
}
}
Any idea on how to prevent this?
Thanks!
