我可以在不打开我的Flutter应用程序的情况下接收共享意图吗?

Question

我正在创建一个应用程序在Flutter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，而不需要打开应用程序让用户输入什么，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。在扑动中可能吗?

这应该工作得很好，根据您的要求，receive_sharing_intent，只是按照android &Ios和尝试的例子:

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，您可以接收文本&媒体文件在关闭和打开的应用程序。

下面的代码片段在关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;
});
});
