Thanks, it also helped, all the comments were helpful indeed.

Update your compile SDK

Zaid syni • Sep 4

Would you mind telling me, that if I dont have a Pixel Real device how would I test that i Have reached compatibility or not. Since I dont think it would be a good idea to upload app and try if warning goes, since it would take so many updates.
Also if you can guide me through it will be helpful. Since on play console, agora and pdf dependencies show the culprits..

You can try with Android 15 beta emulators and aditionally run flutter build appbundle --analyze-size and then open the created JSON file in DevTools to visualize.
