About

Covers implementing Flutter forms using the Form widget with a persistent GlobalKey<FormState> (never recreated in build), TextFormField validators that return error strings or null, and submission logic gated on _formKey.currentState!.validate(). Provides a step-by-step checklist workflow for implementing login screens, data entry forms, and any multi-field input. Warns against creating a new GlobalKey inside the build method.
