  • Present the ImageScannerController modally to prevent invisible nav bar

    Present the ImageScannerController modally to prevent invisible nav bar

    This fixes an issue when presenting the ImageScannerController modally. The partial takeover has a transparent nav bar and therefore you can see the UINavigationController underneath and the UIBarButtonItems are not clearly visible.

    By presenting the view controllers with fullscreen modal presentation style, the nav bar is forced black and the text is legible

    Displaying au blank page on DocumentScannerFlutter.launch with targetSdkVersion 33 on android 13

    Hi,

    While testing my app on a physical pixel 6 running android 13 I came across the issue of a blank screen and no error logged or found while debugging.

    build.gradle : compileSdkVersion 33 targetSdkVersion 33

    Reverting to targetSdkVersion 32 fixes the issue

    can be reproduced on an android 13 simulator

    Doctor summary (to see all details, run flutter doctor -v): [โœ“] Flutter (Channel stable, 3.3.4, on macOS 12.6 21G115 darwin-arm, locale en-GB) [โœ“] Android toolchain - develop for Android devices (Android SDK version 31.0.0) [โœ“] Xcode - develop for iOS and macOS (Xcode 14.0.1) [โœ“] Chrome - develop for the web [โœ“] Android Studio (version 2021.3) [โœ“] VS Code (version 1.72.1) [โœ“] Connected device (5 available) [โœ“] HTTP Host Availability

    Not a big issue but not great for the future

    Hope it helps keep this amazing plugin up to date
