How to reproduce?

When compressing images on iOS devices using flutter_image_compress: 2.4.0, the resulting image often appears blurry, less detailed, or overly compressed, even when using relatively high quality settings (e.g., quality: 80–100).

Logs

Example code (optional)

final compressedBytes = await FlutterImageCompress.compressWithFile(
  file.path,
  minWidth: width,
  minHeight: height,
  quality: 80,
  format: CompressFormat.jpeg,
);
