Transaction class

Transaction represents a unitary transaction in the ArchEthic network.

Constructors

Transaction({String? address, Balance? balance, int? chainLength, List<CrossValidationStamp>? crossValidationStamps, Data? data, List<TransactionInput>? inputs, String? originSignature, String? previousPublicKey, String? previousSignature, required String? type, ValidationStamp? validationStamp, int? version = cVersion})
Transaction.fromJson(Map<String, dynamic> json)
factory
