如何在Flutter中运行Kotlin函数?

Question

我跟随Flutter在https://flutter.dev/docs/development/platform-integration/platform-channels做了什么，但它没有工作。我检查了其他人的工作，还是一无所获。你们有什么建议?

class MainActivity: FlutterFragmentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
GeneratedPluginRegistrant.registerWith(this.getFlutterEngine()!!)
}

private val CHANNEL = "samples.flutter.dev/battery"
override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
super.configureFlutterEngine(flutterEngine)
MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler {
call, result ->
if (call.method == "MyMethod"){
result.success("Hello Kotlin")
}
}
}}

这是颤振本身的方法

static const platform = 
const MethodChannel("samples.flutter.dev/battery");

Future<void> MyMethod() async {
String value = "";
try{
value = await platform.invokeMethod("MyMethod");
}
catch(e){
print(e);
}
print(value);
}

拜托，我在网上试过所有的方法，但都没用。我恳求你帮助我的情况。

我刚刚解决了我的问题。它在AndroidManifest.xml

是

android:name="io.flutter.embedding.android.FlutterFragmentActivity"

我改回

android:name=".MainActivity"
