| ## Implementation |
| |
| ```dart |
| void hexDump() { |
| const int width = 16; |
| Uint8List list = Uint8List.view(data.buffer, 0); |
| StringBuffer buffer = StringBuffer(); |
| final RegExp isPrintable = RegExp(r'\w'); |
| for (int i = 0; i < data.lengthInBytes; i += width) { |
| StringBuffer hex = StringBuffer(); |
| StringBuffer printable = StringBuffer(); |
| for (int j = 0; j < width && i + j < data.lengthInBytes; j++) { |
| int v = list[i + j]; |
| String s = v.toRadixString(16); |
| if (s.length == 1) |
| hex.write('0$s '); |
| else |
| hex.write('$s '); |
| |
| s = String.fromCharCode(v); |
| if (isPrintable.hasMatch(s)) { |
| printable.write(s); |
| } else { |
| printable.write('.'); |
| } |
| } |
| buffer.write('${hex.toString().padRight(3 * width)} $printable\n'); |
| } |
| |
| print('==================================================\n' |
| '$buffer' |
| '=================================================='); |
| } |
