getShort static method

int getShort(Uint8List buffer, int offset)

Converts two bytes of a byte array to a signed 16-bit integer.

The byte order is big-endian.

Implementation

static int getShort(Uint8List buffer, int offset) {
  assert(buffer.length >= offset + 2);
  if (buffer[offset] & 0x80 > 0) {
    return -1 * (((buffer[offset] & 0x7f) ^ 0x7f) << 8 | ((buffer[offset + 1] & 0xff) ^ 0xff) + 1);
  }
  return buffer[offset] << 8 | (buffer[offset + 1] & 0xff);
}
