Without being able clearly able to identify the issue, we downgrade to Flutter 3.0, the time to find a real fix

Hi @g123k!
Looks good to me!
That said, if it's just a matter of isolate, perhaps we would be better off not using isolates while the flutter bug is not fixed.
If I remember well we only use them in the scan process.
That would mean the app would work with flutter 3.3, though it may stutter a little on the scan page.
Just a suggestion: try the app in flutter 3.3 without isolates. Suggestion that you can ignore :)

I'm going to merge this to get the build back in order when it comes to scanning
