Former<TForm extends FormerForm> class

Provides child widgets with the given form that needs to conform to the given schema.

All Former controls should be under Former, and the form they are controlling should be provided by Former.

Under the hood Former stores the form and the schema in FormerProvider, which child widgets can access with Former.of.

Former(
  form: () => MyForm(),
  schema: () => MyFormSchema(
    field1: ...requirements,
    field2: ...requirements,
  ), // automatically generated
  child: child,
),
