when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String id,
    2. String account,
    3. PayAmount amount,
    4. int etaSeconds,
    5. List<Action> actions,
    )
)

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?>(TResult Function( String id,  String account,  PayAmount amount, @JsonKey(name: 'etaS')  int etaSeconds,  List<Action> actions)  $default,) {final _that = this;
switch (_that) {
case _PaymentOption():
return $default(_that.id,_that.account,_that.amount,_that.etaSeconds,_that.actions);}
}
