Question

I want run a existing project. It's fully run on under Android 12 but when I going to run a samsung phone which version is Android 12. Then I get this type of error.

            android:name="flutterEmbedding"
            android:value="2" />

</manifest>

I tried android:exported="true" true and false also. But nothing is worked. How can I solve this ?

Add service to application, it's work for me.

<service android:name="io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService" android:exported="true"/>
