toHexString static method

String toHexString(List<int> dataBytes, { bool lowerCase = true, String? prefix, })

Converts a List of integers representing bytes, dataBytes, into a hexadecimal string.

The method uses the hex library to encode the byte list into a hexadecimal string. It allows customization of the string's case (lowercase or uppercase) using the lowerCase parameter, and an optional prefix string can be appended to the resulting hexadecimal string.

Parameters:

• dataBytes: A List of integers representing bytes to be converted.
• lowerCase: Whether the resulting hexadecimal string should be in lowercase (default is true).
• prefix: An optional string to append as a prefix to the hexadecimal string.

Returns:

• A hexadecimal string representation of dataBytes.

Implementation

static String toHexString(List<int> dataBytes,
    {bool lowerCase = true, String? prefix}) {
  final String toHex = hex.hex.encode(dataBytes, lowerCase: lowerCase);
  return "${prefix ?? ''}$toHex";
}
