Flutter 深度链接

据Flutter官方介绍深层链接页面 https://flutter.dev/docs/development/ui/navigation/deep-linking，我们不需要任何插件或本机 Android/iOS 代码来处理深层链接。

但它并没有真正告诉我们如何从该链接获取数据。我是从编码的角度来谈论的。当然，他们在那里写道：

但这并没有告诉我where我应该写what代码以实际获取完整链接。我寻找过示例/教程，但找不到任何不使用插件来处理深度链接的内容。

现在，我所做的就是添加<intent-filter>标签在AndroidManifest.xml文件并单击链接后，我的应用程序开始显示。但我不知道如何从该链接中提取数据。

有人可以在这里指导我吗？提前致谢。

您需要特定于平台的代码来处理深度链接。如果您点击文档中提到的链接，您将找到完整的示例。

private val CHANNEL = "poc.deeplink.flutter.dev/channel"
private var startString: String? = null
override fun configureFlutterEngine(@NonNull flutterEngine:FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine)

MethodChannel(flutterEngine.dartExecutor, CHANNEL).setMethodCallHandler { call, result ->
    if (call.method == "initialLink") {
        if (startString != null) {
            result.success(startString)
        }
    }
 }
}


override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)

   val intent = getIntent()
   startString = intent.data?.toString()
}

颤振代码：

class DeepLinkBloc extends Bloc {

 //Event Channel creation
static const stream = const 
EventChannel('poc.deeplink.flutter.dev/events');

//Method channel creation
static const platform = const 
MethodChannel('poc.deeplink.flutter.dev/channel');

 StreamController<String> _stateController = StreamController();

 Stream<String> get state => _stateController.stream;

 Sink<String> get stateSink => _stateController.sink;


//Adding the listener into contructor
DeepLinkBloc() {
  //Checking application start by deep link
  startUri().then(_onRedirected);
  //Checking broadcast stream, if deep link was clicked in opened appication

  stream.receiveBroadcastStream().listen((d) => _onRedirected(d));
}


_onRedirected(String uri) {
  // Here can be any uri analysis, checking tokens etc, if it’s necessary
  // Throw deep link URI into the BloC's stream
  stateSink.add(uri);
}


  @override
  void dispose() {
    _stateController.close();
  }


  Future<String> startUri() async {
    try {
      return platform.invokeMethod('initialLink');
    } on PlatformException catch (e) {
      return "Failed to Invoke: '${e.message}'.";
    }
  }
}
