Flutter 调用地图软件（高德、百度、腾讯、苹果）同时实现另类国际化

在Flutter中调用地图软件，可以使用flutter_map和geolocator插件。对于国际化，可以使用flutter_localizations库。以下是一个简单的示例，展示如何在Flutter中同时调用多个地图软件和实现国际化。

1. 在pubspec.yaml中添加依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_map: ^0.9.0
  geolocator: ^7.0.1
  flutter_localizations:
    sdk: flutter

2. 在main.dart中配置地图和国际化支持：

import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:geolocator/geolocator.dart';
 
void main() => runApp(MyApp());
 
class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        // Other theme settings...
      ),
      localizationsDelegates: [
        // Add Flutter bundled localizations delegates
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
        // ... other delegates
      ],
      supportedLocales: [
        const Locale('en', 'US'), // English
        const Locale('zh', 'CN'), // Chinese
        // ... other locales
      ],
      home: MapPage(),
    );
  }
}
 
class MapPage extends StatefulWidget {
  @override
  _MapPageState createState() => _MapPageState();
}
 
class _MapPageState extends State<MapPage> {
  var _currentPosition;
 
  @override
  void initState() {
    super.initState();
    _getCurrentLocation();
  }
 
  // 获取当前位置
  _getCurrentLocation() async {
    Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
    setState(() {
      _currentPosition = position;
    });
  }
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Map Page'),
      ),
      body: _currentPosition == null
          ? Center(child: CircularProgressIndicator())
          : FlutterMap(
              options: MapOptions(
                center: LatLng(_currentPosition.latitude, _currentPosition.longitude),
                zoom: 10.0,
              ),
              layers: [
                TileLayerOptions(
                  urlTemplate: "https://api.tiles.mapbox.com/v4/"
                      "{id}/{z}/{x}/{y}@2x.png?access_token={accessToken}",
                  additionalOptions: {
