Blob.fromStream constructor
Creates a Blob from a stream
of chunks of data.
Usually, an unsaved Blob is saved when a Document that contains it is
saved. This is not possible for Blobs created from a stream
, when the
Document is being saved into a SyncDatabase. In this case, the Blob
must be saved explicitly, with Database.saveBlob.
Implementation
factory Blob.fromStream(String contentType, Stream<Uint8List> stream) =>
BlobImpl.fromStream(contentType, stream);
