galleryButtonType: GalleryButtonType.none incorrectly hides all buttons instead of only the gallery button

[VictorJava]

Steps to reproduce

1. Add dependency ai_barcode_scanner: ^7.1.0
2. Pass galleryButtonType: GalleryButtonType.none to AiBarcodeScanner widget

Actual result
All buttons (flashlight, flip camera, close, etc.) disappear from the scanner screen.
Expected result
Only the “Gallery/Pick from album” button should be hidden. All other control buttons (flash, flip camera, close, etc.) must remain visible and functional.
Please see the attached video for demonstration.
