Update: Actually the error didn't go away but appear at the debug trace. The error occur if only we have an embedded image. The error always occur when set complete/error for the completer.
Really appreciate your help in looking into this issue.

Let me take a look into this ASAP. Can you please attach the output from flutter doctor?

Next version will be 3.1.0 because I also needed to bump the Flutter version due to incompatibilities (breaking changes in Flutter).
