when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>({
  1. required TResult paymentIntent(
    1. PaymentIntent paymentIntent
    ),
  2. required TResult setupIntent(
    1. SetupIntent setupIntent
    ),
})

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>({required TResult Function( PaymentIntent paymentIntent)  paymentIntent,required TResult Function( SetupIntent setupIntent)  setupIntent,}) {final _that = this;
switch (_that) {
case CollectBankAccountPaymentIntentResult():
return paymentIntent(_that.paymentIntent);case CollectBankAccountSetupIntentResult():
return setupIntent(_that.setupIntent);}
}
