GForm class

Thin wrapper around Flutter's Form that uses a GFormController.

Provides the controller to descendants via controllerOf / maybeControllerOf so named gmana_form fields can resolve their text controllers automatically.

Static Methods

controllerOf(BuildContext context) GFormController

maybeControllerOf(BuildContext context) GFormController?
Looks up the nearest enclosing GFormController, or null if none.
