4 years ago I've been unable to reproduce this bug.
I can't see from the stack trace provided that the error is originating from flutter_typeahead. If you are sure this problem is caused by the package, kindly file an issue on the package repo
Can you kindly show your flutter doctor result

4 years ago Hi @danvick , im using Dart 2.9.3 and Flutter 1.20.1 on Windows 10.
I can use TypeAheadField or TypeAheadFormField directly using flutter_typeahead package.
But my other fields are using this flutter_form_builder package. That means, i'ts better to use FormBuilderTypeAhead by this package instead using flutter_typeahead directly.
The problem is, I'm not able to use FormBuilderTypeAhead even for a simple use. I've tried this example (of course adjusted to my need) and it didn't work. Then i tried even for a very simple, it's still not working. I tried to hot restart, also still not working.
However, thanks a lot for creating & maintaining the plugin :)
Here is the debug messages:
