maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String initialTxnReceipt, String initialTxnHash)?, { 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 initialTxnReceipt,  String initialTxnHash)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ExecuteDetailsCompat() when $default != null:
return $default(_that.initialTxnReceipt,_that.initialTxnHash);case _:
  return orElse();

}
}
