related with flutter gradle version - flutter

Question

I changed some codes in gradle files for using external project.
but now facing with problems below, how can I work arrange these?
/AndroidManifest.xml Error:
android:exported needs to be explicitly specified for element <activity#com.example.awesome_flutter_layouts.MainActivity>. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
