EXCEPTION CAUGHT BY WIDGETS LIBRARY #17968
Description
Hi,
I've just had the following error occurring in my flutter project.
It says to report it, so I have!
Let me know if there's anything further I can help with. I haven't yet found a flaw in my code that is causing this - but that doesn't mean there isn't one!
Many thanks,
Mike
