readBytes method

@override Uint8List readBytes(int length)

Get the bytes from the current index to the length

Example:

final input = Input.fromHex('0x010203');
print(input.readBytes(3)); // [1, 2, 3]

Implementation

@override
Uint8List readBytes(int length) {
  final int beg = offset;
  final int end = offset + length;

  if (end > _buffer.length) {
    throw Exception('End of buffer reached');
  }

  offset = end; // Update the index
  return Uint8List.fromList(
      _buffer.sublist(beg, end).toList()); // Extract the required bytes
}
