maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String? name,
    2. String? email,
    3. String? phone,
    4. PaymentElementBillingDetailsAddress? address,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String? name,  String? email,  String? phone,  PaymentElementBillingDetailsAddress? address)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _PaymentElementBillingDetails() when $default != null:
return $default(_that.name,_that.email,_that.phone,_that.address);case _:
  return orElse();

}
}
