PdfStampExportCallback typedef
PdfStampExportCallback =
Future<void> Function(BuildContext context, List<PdfCustomStamp> stamps)
Saves user-managed custom stamps somewhere outside the editor package.
The stock picker passes only PdfEditingController.savedCustomStamps; host-provided stamps are managed by the host and are not exported here.
Implementation
typedef PdfStampExportCallback = Future<void> Function(
BuildContext context,
List<PdfCustomStamp> stamps,
);
