I have this issue when I build my flutter project to aar and use it from other android project.
When I build apk, then it works properly.

On some device it shows as on Vantirs screenshot, on some there are empty space on top and bottom. Probably dependent of screen size.

Version of barcode_scan2: ^4.2.4
flutter: 3.7.7
