ninja_hex

Dart library to encode, decode and pretty print hex string

Usage

Hex codec

void main() {
  final random = Random();
  final data = List<int>.generate(20, (index) => random.nextInt(256));
  print(data);
  final encoded = data.toHex;
  print(encoded);
  final decoded = encoded.decodeHex;
  print(decoded);
}

Hex view

void main() {
	print(hexView(5, List<int>.generate(125, (i) => i + 5)));
}

Output:

0x00000005	-- -- -- -- -- 05 06 07 08 09 0A 0B 0C 0D 0E 0F
