Retrieving transitionable states

An array of transitionable states can be retrieved using the transitionableStates() on the state field.

abstract class PaymentState extends State
{
    // …

    public static function config(): StateConfig
    {
        return parent::config()
            ->allowTransition(Pending::class, Paid::class)
            ->allowTransition(Paid::class, Refunded::class);
    }
}

$transitionableStates = $payment->state->transitionableStates();

This will return an array with all transitionable states for the current state, for example Pending:

[
    0 => "paid"
]

##Can transition to

If you want to know whether a state can be transitioned to another one, you can use the canTransitionTo method:

$payment->state->canTransitionTo(Paid::class);
