Required validator

[snowfrogdev]

It would be nice if ng-toggle-button could be compatible with Angular Forms' required validator.

Naturally it is compatible, but if the toggle is initialized with a value, you won't have the required error, at least the value would be undefined or null

This is an example using the Form Control required validator, it works when the control does not have a value or the value is null, undefined or '' those are considered as an invalid value. This behavior is either Template-driven Forms or Reactive Forms.

You can use the requiredValue validator if you want to the required value would be true.
