maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(TransactionId id, TransactionId? prevTransactionId, @dateSecondsSinceEpochJsonConverter DateTime createdAt, bool aborted, @JsonKey.new(includeIfNull: false) int? exitCode, @JsonKey.new(includeIfNull: false) int? resultCode, AccountStatus origStatus, AccountStatus endStatus, BigInt totalFees, Message inMessage, List<Message> outMessages, String? boc,)?, { 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( TransactionId id,  TransactionId? prevTransactionId, @dateSecondsSinceEpochJsonConverter  DateTime createdAt,  bool aborted, @JsonKey(includeIfNull: false)  int? exitCode, @JsonKey(includeIfNull: false)  int? resultCode,  AccountStatus origStatus,  AccountStatus endStatus,  BigInt totalFees,  Message inMessage,  List<Message> outMessages,  String? boc)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Transaction() when $default != null:
return $default(_that.id,_that.prevTransactionId,_that.createdAt,_that.aborted,_that.exitCode,_that.resultCode,_that.origStatus,_that.endStatus,_that.totalFees,_that.inMessage,_that.outMessages,_that.boc);case _:
  return orElse();

}
