ReactiveFormBuilder constructor

const ReactiveFormBuilder({ Key? key, required ReactiveFormBuilderCreator form, required ReactiveFormConsumerBuilder builder, bool canPop(FormGroup formGroup)?, void onPopInvoked(FormGroup formGroup, bool didPop)?, Widget? child, })

Creates and instance of ReactiveFormBuilder.

The form and builder arguments must not be null.

Example:

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ReactiveFormBuilder(
      form: (context) => FormGroup({'name': FormControl<String>()}),
      builder: (context, form, child) {
        return ReactiveTextField(
          formControlName: 'name',
        );
      },
    );
  }
}

Example: Allows the route to be popped only if the form is valid.

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ReactiveFormBuilder(
      form: (context) => FormGroup({'name': FormControl<String>()}),
      canPop: (formGroup) => formGroup.valid
      builder: (context, form, child) {
        return ReactiveTextField(
          formControlName: 'name',
        );
      },
    );
  }
}

  super.key,
