trancations method Null safety

Future<BankReponse> trancations(
  1. {required String referenceNumber,
  2. required int noOfTransactions,
  3. required String accessToken}
)

trancations Fetches the baseAccountNo last n transctions, where n is the number of transactions noOfTransactions It has a return type of BankReponse & the raw response can be gotten by calling BankReponse.rawResponceBody The list of transactions as List of BankTransactionModel can be gotten by calling BankReponse.transactions

Implementation

Future<BankReponse> trancations({
  required String referenceNumber,
  required int noOfTransactions,
  required String accessToken,
})async{

  Map<String, String> _header ={
    'content-type': 'application/json',
    'Authorization': 'Bearer $accessToken'
  };

  Map<String, dynamic> _payload = {
    'MessageReference': referenceNumber,
    'AccountNumber': baseAccountNo,
    'NoOfTransactions': noOfTransactions,
  };


  try {
    return await pesalinkProcessTransaction(transactionsUrl, _header, _payload, applicationMode);
  } catch (e) {
    rethrow;
  }
