[英]How can I run Kotlin function in Flutter?
I followed what Flutter did in https://flutter.dev/docs/development/platform-integration/platform-channels but it didn't work.我遵循了 Flutter 在https://flutter.dev/docs/development/platform-integration/platform-channels 中所做的,但没有奏效。 I checked other people's work and still nothing.我检查了其他人的工作,仍然没有。 So what do you guys suggest?那么大家有什么建议呢?
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")
}
}
}}
and this is the method in flutter itself这就是颤振本身的方法
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);
}
Please, I've tried everything on internet but none of them worked.拜托,我已经在互联网上尝试了一切,但没有一个奏效。 I beg your help for my case.我请求你帮助我的案子。
I just solved my issue.我刚刚解决了我的问题。 It was in AndroidManifest.xml它在 AndroidManifest.xml 中
it was它是
android:name="io.flutter.embedding.android.FlutterFragmentActivity"
I changed it back to我把它改回
android:name=".MainActivity"
