• fields (rest): readonly FormField<any, TValidationError>[]
  The fields to add to the form.

Returns a collection containing the provided fields. The form reacts to changes made in the returned collection always keeping in sync.

This method adds the provided fields to the form, a necessary step to watch the form fields for changes as well as their validity. The Form.isValid and Form.isInvalid properties are dependent on the fields.

class MyForm extends Form {
  public constructor() {
    super();

    this.withFields(
      this.name = new FormField({
        name: 'name',
        initialValue: ''
      })
    );
  }

  public readonly name: FormField<string>;
}
