Hooks

Hooks can be used to perform important operations before and after state transitions.

Before hook

In the example below, we can execute one or multiple hooks before transitioning states.

 public static function states(): array{
    return [
      State::on(
        ...
        before: function($fromState, $toState){
          //
        },
      ),
      State::on(
        ...
        before: [
          function(){
            //
          }
        ],
      ),
    ];
}

If any of the hooks return false, the transition is exited.

After hook

Likewise for after a state has been transitioned.

 public static function states(): array{
    return [
      State::on(
        ...
        after: function(){
          //
        },
      ),
      State::on(
        ...
        after: [
          function(){
            //
          }
        ],
      ),
    ];
}
