我正在 Flutter 中创建一个应用程序来存储任何类型的媒体、图像、视频、pdf 等。我希望能够以最简单的方式为用户接收来自其他应用程序的共享意图。

所以，我的想法是能够简单地接收媒体而无需打开应用程序让用户输入内容，他们应该简单地选择我的应用程序来接收媒体并继续使用“源”应用程序。这在颤振中可能吗？

根据您的要求， receive_sharing_intent应该可以很好地工作，只需按照 android 和 ios 的设置并尝试示例：

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

import 'package:receive_sharing_intent/receive_sharing_intent.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  StreamSubscription _intentDataStreamSubscription;
  List<SharedMediaFile> _sharedFiles;
  String _sharedText;

  @override
  void initState() {
    super.initState();

    // For sharing images coming from outside the app while the app is in the memory
    _intentDataStreamSubscription =
        ReceiveSharingIntent.getMediaStream().listen((List<SharedMediaFile> value) {
      setState(() {
        print("Shared:" + (_sharedFiles?.map((f)=> f.path)?.join(",") ?? ""));
        _sharedFiles = value;
      });
    }, onError: (err) {
      print("getIntentDataStream error: $err");
    });

    // For sharing images coming from outside the app while the app is closed
    ReceiveSharingIntent.getInitialMedia().then((List<SharedMediaFile> value) {
      setState(() {
        _sharedFiles = value;
      });
    });

    // For sharing or opening urls/text coming from outside the app while the app is in the memory
    _intentDataStreamSubscription =
        ReceiveSharingIntent.getTextStream().listen((String value) {
      setState(() {
        _sharedText = value;
      });
    }, onError: (err) {
      print("getLinkStream error: $err");
    });

    // For sharing or opening urls/text coming from outside the app while the app is closed
    ReceiveSharingIntent.getInitialText().then((String value) {
      setState(() {
        _sharedText = value;
      });
    });
  }

  @override
  void dispose() {
    _intentDataStreamSubscription.cancel();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    const textStyleBold = const TextStyle(fontWeight: FontWeight.bold);
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Column(
            children: <Widget>[
              Text("Shared files:", style: textStyleBold),
              Text(_sharedFiles?.map((f)=> f.path)?.join(",") ?? ""),
              SizedBox(height: 100),
              Text("Shared urls/text:", style: textStyleBold),
              Text(_sharedText ?? "")
            ],
          ),
        ),
      ),
    );
  }
}

使用接收共享意图包，您可以在关闭和打开的应用程序中接收文本和媒体文件。

下面的代码片段在封闭的应用程序中接收意图，

// For sharing images coming from outside the app while the app is closed
    ReceiveSharingIntent.getInitialMedia().then((List<SharedMediaFile> value) {
      setState(() {
        _sharedFiles = value;
      });
    });

您可以通过此链接进一步了解如何在已打开和关闭的应用程序中接收意图。
