my code change String "main" to "topMain"

class SingleFlutterActivity : FlutterActivity(), EngineBindingsDelegate {
    private val engineBindings: EngineBindings by lazy {
        EngineBindings(activity = this, delegate = this, entrypoint = "topMain")
    }

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

    override fun onDestroy() {
        super.onDestroy()
        engineBindings.detach()
    }

    override fun provideFlutterEngine(context: Context): FlutterEngine? {
        return engineBindings.engine
    }

    override fun onNext() {
        val flutterIntent = Intent(this, MainActivity::class.java)
        startActivity(flutterIntent)
    }
}

Any ideas what is going wrong here @gaaclarke?

[gaaclarke]

It may be this: flutter/flutter#91841 I'd try on the master channel.
