You are creating a Flutter form that should auto-save its state whenever a user interacts with any field. Which Flutter feature should you use?
- AutoSaveMixin and StatefulWidget
- FormState and GlobalKey
- SharedPreferences and LocalStore
- TextEditingController and FormField
To auto-save the state of a Flutter form upon interaction with any field, you should use FormState and GlobalKey. FormState represents the state of a Form and can be used to save, reset, and interact with the form. GlobalKey is used to uniquely identify the form and manage its state across different parts of your application. Using these, you can implement auto-saving functionality and maintain the form's state seamlessly.
