For my current application I need to be able to specify the errorText for a specific field, without resulting in the usage of the built in forms feature. I perform my validation in BLOCs and cannot rely on built-in validation. I need to be able to specify the errorText to the dropdown button, however this currently is not possible. If this could be added, I'd be very grateful.
The same thing happens to me, I can't validate the dropdown because I use Formz and the DropdownButtonFormField2 doesn't have the errorText option in the decoration.
