sanitizePaddingZeros function

Implementation

Uint16List sanitizePaddingZeros(Uint16List msg) {
  int lastNonZeroIdx = msg.length - 1;
  while (msg[lastNonZeroIdx] == 0) {
    --lastNonZeroIdx;
  }
  Uint16List sanitized =
      Uint16List.fromList(msg.getRange(0, lastNonZeroIdx + 1).toList());
  return sanitized;
}
