如何获得所有详细的地址时，我被放在谷歌地图上的标记。然后它会在flutter的文本框中填满

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Address',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final String address = '在这里填写详细地址'; // 将详细地址信息填写在这里

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Address'),
      ),
      body: Center(
        child: Text(
          address,
          style: TextStyle(fontSize: 20),
        ),
      ),
    );
  }
}
