To reset a Flutter Map after a certain duration, such as 10 seconds, you can use Flutter's `Timer` class to trigger the reset action. Here's a basic example of how to do this:
Assuming you have a `FlutterMap` widget and a `MapController` set up:
```dart
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong/latlong.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: MyMapPage(),
);
}
}
class MyMapPage extends StatefulWidget {
@override
_MyMapPageState createState() => _MyMapPageState();
}
class _MyMapPageState extends State<MyMapPage> {
MapController _mapController = MapController();
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Flutter Map Reset Example")),
body: FlutterMap(
mapController: _mapController,
options: MapOptions(
center: LatLng(51.5, -0.09),
zoom: 13.0,
),
layers: [
TileLayerOptions(
urlTemplate: "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
subdomains: ['a', 'b', 'c'],
),
],
),
);
}
@override
void initState() {
super.initState();
// Reset the map after 10 seconds
Timer(Duration(seconds: 10), resetMap);
}
void resetMap() {
_mapController.move(LatLng(51.5, -0.09), 13.0);
}
}
```
In this example:
1. We create a `MapController` to control the state of the `FlutterMap` widget.
2. In the `initState`, we set a timer to call the `resetMap` function after 10 seconds.
3. The `resetMap` function moves the map to the initial position or any other position you desire.
Make sure to customize the `LatLng` and zoom level in the `resetMap` function according to your requirements.
This code will reset the map to the specified location after 10 seconds.
