PrismForm class

Declarative form container.

Owns a PrismFormController (or adopts controller) and exposes it to child field widgets. Wrap submit buttons with an ListenableBuilder on the controller to react to the sealed PrismFormStatus.

final controller = PrismFormController();

PrismForm(
  controller: controller,
  child: Column(
    children: [
      PrismTextField(name: 'email', label: 'Email', validators: [Validators.required(), Validators.email()]),
      PrismPasswordField(name: 'password'),
      // submit button…
    ],
  ),
)
