On Flutter 3.7.9 this package returns only empty image on web

[NZhlebinkov]

I used the example code from here: https://pub.dev/packages/crop_image/example and changed the photo to a local jpg asset that I have.

I run the code with CanvasKit and profile mode as outlined here and here

And I have all the nice buttons, I can rotate and select aspect ratios and all, and when I click done I see the correct Rect has been calculated. However the cropped image is not displayed.

I've spent hours debugging and what I've found is that the image contains only 0s. What does that mean?

final bitmap =  controller.croppedBitmap();
final bytes = (await bitmap.toByteData())?.buffer.asUint8List();

here, the bytes are all 0 when I print them.

I haven't found a way to use this package on web on Flutter 3.7.9, has anyone else been able to get it to work?

Does this mean from 3.7.9 onwards or specifically on that version? We're on .12 stable now and I couldn't reproduce the issue there.

Which Flutter version did you try it on?
