  20. ShowErrorsFunction<bool>? showErrors,
})

Create an instance of a ReactiveCheckbox.

Can optionally provide a formControl to bind this widget to a control.

Can optionally provide a formControlName to bind this ReactiveFormField to a FormControl.

Must provide one of the arguments formControl or a formControlName, but not both at the same time.

For documentation about the various parameters, see the Checkbox class and the Checkbox constructor.
