可以使用Flutter应用中的Intent启动另一个Activity: https://github.com/flutter/flutter/blob/master/examples/widgets/launch_url.dart
import 'package:flutter/widgets.dart';
import 'package:flutter/services.dart';
void main() {
runApp(new GestureDetector(
onTap: () {
Intent intent = new Intent()
..action = 'android.intent.action.VIEW'
..url = 'http://flutter.io/';
activity.startActivity(intent);
},
child: new Container(
decoration: const BoxDecoration(
backgroundColor: const Color(0xFF006600)
),
child: new Center(
child: new Text('Tap to launch a URL!')
)
)
));
}
但是当Intent传递给应用程序时,可以使用Flutter Activity Intent服务执行以下操作吗? http://developer.android.com/training/sharing/receive.html
. . .
void onCreate (Bundle savedInstanceState) {
...
// Get intent, action and MIME type
Intent intent = getIntent();
. . .

据我所知,目前无法从Dart代码处理传入的Intent。具体而言,处理传入URL的情况由https://github.com/flutter/flutter/issues/357跟踪。
它还可以处理来自Java代码的传入意图,并使用https://flutter.io/platform-services/
中记录的HostMessage系统将结果发布到Dart答案 1 :(得分:2)
这也许可以帮助您,硫代物表明如何处理 https://flutter.io/flutter-for-android/#what-is-the-equivalent-of-an-intent-in-flutter
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<!-- ... -->
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
在MainActivity上
public class MainActivity extends FlutterActivity {
private String sharedText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
if (Intent.ACTION_SEND.equals(action) && type != null) {
if ("text/plain".equals(type)) {
handleSendText(intent); // Handle text being sent
}
}
MethodChannel(getFlutterView(), "app.channel.shared.data")
.setMethodCallHandler(MethodChannel.MethodCallHandler() {
@Override
public void onMethodCall(MethodCall methodCall, MethodChannel.Result result) {
if (methodCall.method.contentEquals("getSharedText")) {
result.success(sharedText);
sharedText = null;
}
}
});
}
void handleSendText(Intent intent) {
sharedText = intent.getStringExtra(Intent.EXTRA_TEXT);
}
}
最后得到它
class _SampleAppPageState extends State<SampleAppPage> {
static const platform = const MethodChannel('app.channel.shared.data');
String dataShared = "No data";
@override
void initState() {
super.initState();
getSharedText();
}
@override
Widget build(BuildContext context) {
return Scaffold(body: Center(child: Text(dataShared)));
}
getSharedText() async {
var sharedData = await platform.invokeMethod("getSharedText");
if (sharedData != null) {
setState(() {
dataShared = sharedData;
});
}
}
}
但是如果需要向android系统发送真实意图,则可以使用此库
