terminalDoInit method

@override Future<ApiResponse<DataInitRet>> terminalDoInit({ required String terminalId, required String trc, })

To make a transaction, you must create a terminal initial connection using the previously provided terminalId and Trc code.

Implementation

@override

    {required String terminalId, required String trc}) async {
