And during the debug i have this log before the crash :
flutter_image_compress_macos/FlutterImageCompressMacosPlugin.swift:319: Fatal error: Unexpectedly found nil while unwrapping an Optional value
Example code (optional)
XFile? file = await FlutterImageCompress.compressAndGetFile(photoPath, output, minHeight: minHeight, minWidth: minWidth, quality: quality);
