Alias: FlashMemoryStream
This is a Sming IDataSourceStream descendant which you can use to stream the contents of a FlashString. It's especially useful when used in conjuction with IMPORT_FSTR:
IMPORT_FSTR(myLargeFile, PROJECT_DIR "/files/lots-of-stuff.txt"); FlashMemoryStream fs(myLargeFile); Serial.println(myLargefile);
Because the data is read in sections, it's not limited by available RAM.
Like a FileStream, you can also seek randomly within a FlashMemoryStream, so you can use it as the basis for an elementary read-only filesystem. See :doc:`maps` for a more useful example.
