Flutter调用Android模块的功能

Flutter调用Android模块的功能，主要通过MethodChannel

Flutter端

const MethodChannel _channel = const MethodChannel('videoUrl');
  try {
    videoUrl = await _channel.invokeMethod<String>("getVideoUrl", {
      "base64Str": video_detail_model.data.courseUrl
    });
  } catch (e) {
    print(e.message);
  }

Android端

public class MainActivity extends FlutterActivity {

private static final String channel = "videoUrl";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    new MethodChannel(getFlutterEngine().getDartExecutor().getBinaryMessenger(),channel).setMethodCallHandler(
            new MethodChannel.MethodCallHandler() {
                @Override
                public void onMethodCall(MethodCall methodCall, MethodChannel.Result result) {

                    if (methodCall.method.equals("getVideoUrl")) {
                        result.success(getVideoUrl(methodCall.argument("base64Str")));
                    } else {
                        result.notImplemented();
                    }
                }
            }
    );
    

}



private String getVideoUrl(String base64Str){
    return Base64Util.getUrl(base64Str,this);
}

}

关键点channel名字要一样
