RawAutocomplete with TextFormField does not allow user to enter text from soft keyboard on Android

[BellRampion]

Steps to Reproduce

1. Execute flutter run on the code sample
2. Click on the textfield
3. Try to enter text using the soft keyboard
4. Click on the "AAAAAAAAAAAAAAAA" suggestion
5. Delete all the characters
6. Attempt to type more characters

Expected results:
Expected to be able to type characters without first selecting a suggestion.

Actual results:
Cannot enter characters without first selecting a suggestion. Deleting all the characters after selecting a suggestion also prevents entering more characters until a new suggestion is selected.

The Debug Console shows this error every time a key is pressed:
I/TextInputPlugin(15340): Composing region changed by the framework. Restarting the input method.

Hi @BellRampion, the issue you're facing is due to you calling onFieldSubmitted in the onChanged property of your TextField.

If you remove that method call from onChanged, this works as expected.

See https://api.flutter.dev/flutter/widgets/RawAutocomplete-class.html for an example of how to use the RawAutoComplete.

I'll be closing this as it is an implementation issue.

Thank you

[BellRampion]

Thank you! I misread the docs and thought it was called in onChanged instead of onFieldSubmitted.
