What is your flutter version and android target SDK ?

I think you use a version of flutter above 3.27 and target android sdk 15 (directly or indirectly by the flutter version), the issue come from the overlay you add.

• SystemChrome.setEnabledSystemUIMode(SystemUiMode.edgeToEdge); can be removed because edge to edge is default mode on 3.27 and above.
• SystemUiOverlayStyle(...) can be removed because it's deprected and had no effect.

I think removing your customOverlayStyle() will have no effect and will remove the store recommendation.
