@Lcccocoa Did you find the root cause or a way to fix it ?

When we invoke the method, that's where it eventually crashes. The return statement is never reached. This is a relatively new project.

Having the same issue :/ Will be using the image package until it's fixed. I would also like to help fix it (if required).

Looking at the source code it seems that UIImageJPEGRepresentation can return nil in some cases in the CompressHandler class. then FlutterStandardTypedData typedDataWithBytes:compressedData in CompressListHandler crash.

I can create a pr if this repo is still active.
