when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String orchestrationId,
    2. TransactionCompat initialTransaction,
    3. List<TransactionCompat> transactions,
    4. MetadataCompat metadata,
    )
)

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 orchestrationId,  TransactionCompat initialTransaction,  List<TransactionCompat> transactions,  MetadataCompat metadata)  $default,) {final _that = this;
switch (_that) {
case _PrepareResponseAvailableCompat():
return $default(_that.orchestrationId,_that.initialTransaction,_that.transactions,_that.metadata);}
}
