[Bug]: Broken retrocompatibility with serialized images

[saif-ellafi]

Package Version

8.0.0

Flutter Version

3.27.3

Platforms

iOS, Android, Web, macOS, Windows, Linux

How to reproduce?

Some images are getting stuck in "Changes are being applied" forever, the editor never closes to save and finish.

What I noticed:
The images crashing, were ones from before 7.x.x with serialized stickers inside. At 7.x.x they were still working, retrocompatible.

For some reason now at version 8, serialized images now fully disappear after the first save. Further state load and save gets stuck in "Changes are being applied" forever when saving, with the Sticker completely gone or replaced with a Text Widget in Red.

I would need to continue investigating further, but this does not happen with Stickers that were not serialized and metadata was included, only with pre <7.0.0 serialized images.

Is this expected?

Thanks!

I have the gut feeling the library is having an issue when trying to save a Sticker that was serialized in the State, it seems to be failing to generate a new image.

That sounds interesting! I’ll take a look at it. Do you maybe have a demo JSON history that I could use to test it directly?

@hm21 here they are (1. generated image, 2. base image, 3. history file for State, and 4. the image representing the sticker that was serialized)
