hash in Montypay for flutter

After reading this docs I stuck on certain field "hash" how to generate it like the wanted

enter image description here

      String orderNumber = "order-1234";
      String orderAmount = "0.19";
      String orderCurrency = "usd";
      String orderDescription = "Important gift";
      String merchantPass = "merchantPass";
      final inputString =
          '$orderNumber$orderAmount$orderCurrency$orderDescription$merchantPass';
      final utf8Bytes = utf8.encode(inputString);
      final hash = md5.convert(utf8Bytes);
      final hashString = bytesToHex(hash.bytes).toUpperCase();


String bytesToHex(List<int> bytes) {
const hexDigits = '0123456789ABCDEF';
return bytes
    .map((byte) => hexDigits[(byte & 0xff) >> 4] + hexDigits[byte & 0x0f])
    .join('');

}

I'm trying to put hashString in hash field, but every time the response is

{
"error_code": 0,
"error_message": "Request data is invalid.",
"errors": [
    {
        "error_code": 100000,
        "error_message": "hash: Hash is not valid."
    }
]

}

and this from postman

enter image description here

also in collection there is pre request how I can take hash from it enter image description here

Any ideas how to make it in the app?

you need to Set up and select Environment for Checkout, which contains information on host, keys and hash. Environment settings can be updated manually or by importing JSON-format file. JSON file and/or values (CHECKOUT_HOST, merch1_pass_post, variable_key) are provided by Account manager or created manually in the Merchants section of your dashboard . checkout this pdf:https://montypay.com/Postman-Request-Sending.pdf

It should be uppercased first

Example from their docs in PHP: Example from their docs in PHP

Example: Must be SHA1 of MD5 encoded string (uppercased): order_number

  • order_amount + order_currency + order_description + password
