getData method

Uint8List getData()

Gets the the data of the VDS as a binary array.

return The data of the VDS as a binary array. throws BiosealException An error has occurred during Bioseal Library execution.

Implementation

Uint8List getData() {
  Pointer<UnsignedChar> pData = nullptr;
  Pointer<Int> pDataSize = calloc();
  pDataSize[0] = -1;
  try {
    var err = biosealSDK.id3Bioseal_GetData(_pHandle.value, pData, pDataSize);
    if (err == BiosealError.insufficientBuffer.value) {
      pData = calloc.allocate(pDataSize.value);
      err = biosealSDK.id3Bioseal_GetData(_pHandle.value, pData, pDataSize);
    }
    if (err != BiosealError.success.value) {
      throw BiosealException(err);
    }
    final vData = Uint8List.fromList(pData.cast<Uint8>().asTypedList(pDataSize.value));
    return vData;
  } finally {
    calloc.free(pData);
    calloc.free(pDataSize);
  }
