Flutter谷歌地点选择插件flutter_google_places_sdk_macos的使用

Flutter谷歌地点选择插件flutter_google_places_sdk_macos的使用

flutter_google_places_sdk_macos 是 flutter_google_places 插件的 macOS 实现。它允许你在macOS应用中集成谷歌地点选择功能。

使用步骤

首先，你需要在你的项目中添加对 flutter_google_places_sdk_macos 插件的依赖。打开你的 pubspec.yaml 文件，并添加以下依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_google_places_sdk: # 添加这个依赖

然后运行 flutter pub get 来获取新添加的依赖。

初始化插件

在你的 Dart 代码中初始化插件：

import 'package:flutter/material.dart';
import 'package:flutter_google_places_sdk/flutter_google_places_sdk.dart';

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Google Places Demo'),
        ),
        body: GooglePlacesWidget(),
      ),
    );
  }
}

class GooglePlacesWidget extends StatefulWidget {
  [@override](/user/override)
  _GooglePlacesWidgetState createState() => _GooglePlacesWidgetState();
}

class _GooglePlacesWidgetState extends State<GooglePlacesWidget> {
  String _selectedPlace = '';

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Center(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Text(_selectedPlace),
          ElevatedButton(
            onPressed: () async {
              final selectedPlace = await showGooglePlacesPicker(
                apiKey: 'YOUR_API_KEY', // 替换为你的API密钥
                languageCode: 'en',
                regionCode: 'US',
              );

              if (selectedPlace != null) {
                setState(() {
                  _selectedPlace = selectedPlace.name;
                });
              }
            },
            child: Text('选择地点'),
          ),
        ],
      ),
    );
  }
}

限制

这是macOS平台上的初始版本，目前以下方法尚未实现：

• fetchPlace
• fetchPlacePhoto

        ),
        body: GooglePlacesWidget(),
      ),
    );
  }
}

class GooglePlacesWidget extends StatefulWidget {
  [@override](/user/override)
  _GooglePlacesWidgetState createState() => _GooglePlacesWidgetState();
}

class _GooglePlacesWidgetState extends State<GooglePlacesWidget> {
  String _selectedPlace = '';

  [@override](/user/override)

                languageCode: 'en',
                regionCode: 'US',
              );

              if (selectedPlace != null) {
                setState(() {
                  _selectedPlace = selectedPlace.name;
                });
              }
            },
            child: Text('选择地点'),
          ),
        ],
      ),
