PayloadSpec class
A binary chunk in the document's payload manifest: a descriptor plus, when the document's payloads are loaded, the chunk bytes.
The descriptor is what the text form carries; the bytes live in the package and are attached when the document's payloads are loaded.
Constructors
- PayloadSpec(LocalId id, {required PayloadEncoding encoding, String? layout, String? format, int? width, int? height, int? length, Uint8List? bytes})
-
Creates a payload descriptor with the given stable
id.
Properties
- bytes ↔ Uint8List?
-
The chunk bytes, when the document's payloads are loaded; otherwise
null (a manifest-only document).
