Thank you for your report. This problem is caused by an issue upstream.

[clragon]

The issue has already been fixed on the master branch of the flutter sdk. We will have to wait for the next flutter release for this issue to resolve here.

[Poloten]

Today Flutter upgraded to 3.19.0 from 3.16.9. Error not throw, but focus not changed to next field, only the keyboard hide. I also add FocusScope.of(context).nextFocus(), but nothing happens.

textInputAction: TextInputAction.next,
onEditingComplete: () {
  FocusScope.of(context).nextFocus();
},

[animator]

+1 for this issue.

Has anyone managed to navigate between the options with the arrow keys?
