# getOutputData method

Uint8List getOutputData()

Gets the the external resource data as a byte array.

return The external resource data as a byte array. throws BiosealException An error has occurred during Bioseal Library execution.

## Implementation

    Uint8List getOutputData() {
      Pointer<UnsignedChar> pOutputData = nullptr;
      Pointer<Int> pOutputDataSize = calloc();
      pOutputDataSize[0] = -1;
      try {
        var err = biosealSDK.id3BiosealResourceCallbackArgs_GetOutputData(_pHandle.value, pOutputData, pOutputDataSize);
        if (err == BiosealError.insufficientBuffer.value) {
          pOutputData = calloc.allocate(pOutputDataSize.value);
          err = biosealSDK.id3BiosealResourceCallbackArgs_GetOutputData(_pHandle.value, pOutputData, pOutputDataSize);
        }
        if (err != BiosealError.success.value) {
          throw BiosealException(err);
        }
        final vOutputData = Uint8List.fromList(pOutputData.cast<Uint8>().asTypedList(pOutputDataSize.value));
        return vOutputData;
      } finally {
        calloc.free(pOutputData);
        calloc.free(pOutputDataSize);
      }
    }
