Flutter分享功能插件flutter_share_plus的使用

Flutter分享功能插件flutter_share_plus的使用

Flutter 插件用于分享文本和图片等。

开始使用

在 pubspec.yaml 文件中添加依赖：

dependencies:
  flutter_share_plus:

确保运行 flutter pub get 以获取新添加的依赖项。

分享单个文本

以下是一个示例代码，展示如何通过按钮点击事件来分享单个文本：

Future<void> share_text(String message) async {
  await _channel.invokeMethod('share_text', <String, String>{
    'message': message
  });
}

// 在按钮的点击事件中调用该函数
ElevatedButton(
  onPressed: () {
    share_text("message111");
  },
  child: Text("点击我分享单个文本"),
)

分享多个文本

以下是一个示例代码，展示如何通过按钮点击事件来分享多个文本：

Future<void> share_multiline_text(String title, String description) async {
  await _channel.invokeMethod('share_multiline_text', <String, String>{
    'title': title,
    'description': description
  });
}

// 在按钮的点击事件中调用该函数
ElevatedButton(
  onPressed: () {
    share_multiline_text("title111", "description111");
  },
  child: Text("点击我分享多个文本"),
)

完整示例代码

以下是一个完整的示例代码，展示了如何在 Flutter 应用中集成 flutter_share_plus 插件，并实现分享功能：

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter_share_plus/flutter_share_plus.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  static const _channel = MethodChannel("flutter_share_plus");

  Future<void> initPlatformState() async {
    String platformVersion;
    try {
      platformVersion = await FlutterSharePlus.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  Future<void> share_text(String message) async {
    await _channel
        .invokeMethod('share_text', <String, String>{'message': message});
  }

  Future<void> share_multiline_text(String title, String description) async {
    await _channel.invokeMethod('share_multiline_text',
        <String, String>{'title': title, 'description': description});
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return SafeArea(
        child: Scaffold(
      body: Container(
        alignment: Alignment.center,
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: CrossAxisAlignment.center,
          children: <Widget>[
            Container(
              margin: EdgeInsets.all(16),
              child: Text(
                "平台版本: ${_platformVersion}",
                style: TextStyle(fontSize: 20, color: Colors.red),
              ),
            ),
            ElevatedButton(
                onPressed: () {
                  initPlatformState();
                },
                child: Text("点击我获取版本信息")),
            ElevatedButton(
                onPressed: () {
                  share_text("message111");
                },
                child: Text("点击我分享单个文本")),
            ElevatedButton(
                onPressed: () {
                  share_multiline_text("title111", "description111");
                },
                child: Text("点击我分享多个文本"))
          ],
        ),
      ),
    ));
  }
