lastRevisionDelta property

PdfWorkerRevisionDelta? get lastRevisionDelta

The byte-level shape of the most recent revision transition (edit, undo, redo) for the render worker's incremental update path, or null when the last transition cannot be applied incrementally (the initial open, a page structure change, or a redaction burn that replaced the buffer). Only meaningful the moment document's identity changes; the shell reads it then and ignores it otherwise.

Implementation

PdfWorkerRevisionDelta? get lastRevisionDelta => _lastRevisionDelta;
