Hi @masterboltdev - Thanks for posting this issue. I tested dropdown with values from backend and also app states. I do not see any issue and app builds can run fine.

Can you share images or video clips showing the error details?

[masterboltdev]

I've attached 2 series of images. ff-1, ff-1b show the builder without an initial value set and the code generated. ff-2, ff-2a, ff-2b show the value set in the builder, the failed build screen and the code generated. The error message is: A value of type 'String?' can't be assigned to a variable of type 'String'. Try changing the type of the variable, or casting the right-hand type to 'String'.dartinvalid_assignment <https://dart.dev/diagnostics/invalid_assignment> View Problem (Alt+F8) Quick Fix... (Ctrl+.) I have reproduced this repeatedly., including the time to generate these images. Dave

This issue is stale because it has been open for 7 days with no activity. If there are no further updates, a team member will close the issue.

There had been nothing done with this. The error still occurs. I have seen nothing that indicates that anything was done. Closing this won’t make the bug go away.  This bug is easily reproducible. Sent from my iPhoneOn Mar 7, 2023, at 9:05 PM, github-actions[bot] ***@***.***> wrote: This issue is stale because it has been open for 7 days with no activity.

It still is generating the bad code.  There has been no change. Sent from my iPhoneOn Mar 16, 2023, at 9:57 PM, github-actions[bot] ***@***.***> wrote: This issue is stale because it has been open for 7 days with no activity.
