flutter pub add flutter_share基于插件公开信息、社区数据与项目使用情况整理的选型参考。
Flutter Share 是一个轻量级的 Flutter 包，可实现从 Android 和 iOS 应用中无缝分享消息、链接和文件。它提供了一个简单的 API 来集成原生分享意图，使用户能够通过系统对话框分享内容。该包支持文本和文件分享，非常适合需要快速分享功能的应用程序。通过 pub add 进行最少设置即可跨平台使用，无需编写特定于平台的代码。源代码在 GitHub 上开源，鼓励透明度和社区贡献。
以下为关联源码仓库的 README 原文快照，最新内容请访问源码仓库。
A Flutter plugin for IOS and Android providing a simple way to share a message, link or local files.
First, add flutter_share as a dependency in your pubspec.yaml file.
Add if not exists one row to the ios/podfile after target runner:
...
target 'Runner' do
use_frameworks!
...
If you pretends to use the file share, you need to configure the file provider, this will give access to the files turning possible to share with other applications.
Add to AndroidManifest.xml:
<application>
...
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
</application>
Obs: You can change the android:name if you have an extension of file provider.
Add res/xml/provider_paths.xml:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>

Here is an example flutter app displaying the two shares methods. (I'm using documents_picker just to get a local file you don't need to use.)
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:flutter_share/flutter_share.dart';
import 'package:documents_picker/documents_picker.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
Future<void> share() async {
await FlutterShare.share(
title: 'Example share',
text: 'Example share text',
linkUrl: 'https://flutter.dev/',
chooserTitle: 'Example Chooser Title'
);
}
Future<void> shareFile() async {
List<dynamic> docs = await DocumentsPicker.pickDocuments;
if (docs == null || docs.isEmpty) return null;
await FlutterShare.shareFile(
title: 'Example share',
text: 'Example share text',
filePath: docs[0] as String,
);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
child: Text('Share text and link'),
onPressed: share,
),
FlatButton(
child: Text('Share local file'),
onPressed: shareFile,
),
],
),
),
),
);
}
}
