toHex function

String toHex(
  1. List<int> input, {
  2. Base16Codec? codec,
  3. bool upper = false,
})

Converts 8-bit integer sequence to 4-bit Base-16 character sequence.

Parameters:

  • input is a sequence of 8-bit integers.
  • If upper is true, the uppercase standard alphabet is used.
  • codec is the Base16Codec to use. It is derived from the other parameters if not provided.

Implementation

String toHex(
  List<int> input, {
  Base16Codec? codec,
  bool upper = false,
}) {
  codec ??= _codecFromParameters(upper: upper);
  var out = codec.encoder.convert(input);
  return String.fromCharCodes(out);
}
