Example:

In most cases, any input form widget have a value and onChanged properties. You must set these properties to the exposed value and onChanged of OnFormFieldBuilder. This is an example of CheckBox input field

  final myCheckBox = RM.injectFormField<bool>(false);

  //In the widget tree
  OnFormFieldBuilder<bool>(
   listenTo: myCheckBox,
   builder: (value, onChanged) {
     return CheckboxListTile(
       value: value,
       onChanged: onChanged,
       title: Text('I accept the licence'),
     );
   },
  ),
