FormValidator class

Form Validation Helper.

Bridges Magic validation rules with Flutter's native Form widgets. Use FormValidator.rules() to create validators for WFormInput, TextFormField, or any FormField widget.

Recommended Usage with WFormInput

final _formKey = GlobalKey<FormState>();
final _email = TextEditingController();

Form(
  key: _formKey,
  child: Column(
    children: [
      WFormInput(
        controller: _email,
        type: InputType.email,
        label: 'Email',
        className: 'p-3 border rounded-lg error:border-red-500',
        validator: FormValidator.rules(
          [Required(), Email()],
          field: 'email',
        ),
      ),
      FilledButton(
        onPressed: () {
          if (_formKey.currentState!.validate()) {
            // Form valid! Send clean data to controller
            controller.attemptLogin(email: _email.text.trim());
          }
        },
        child: Text('Submit'),
      ),
    ],
  ),
)

With Password Confirmation

final _password = TextEditingController();
final _passwordConfirm = TextEditingController();

WFormInput(
  controller: _passwordConfirm,
  type: InputType.password,
  label: 'Confirm Password',
  validator: FormValidator.rules(
    [Required(), Same('password')],
    field: 'password confirmation',
    extraData: {'password': _password.text},
  ),
)
