没找到 registerfor 只有一个
registerForContextMenu

里面传的参数也不一样 不知道怎么传了

class MainActivity: FlutterActivity() {

override fun onCreate(savedInstanceState: Bundle?, persistentState: PersistableBundle?) {
    super.onCreate(savedInstanceState, persistentState)
    GeneratedPluginRegistrant.registerWith(FlutterEngine(this));
    registerSelfPlugin();

}

private fun registerSelfPlugin() {
    AsrPlugin.registerWith(registerForContextMenu())
}

}
