SfPdfViewer class
A widget to view PDF documents.
SfPdfViewer lets you display the PDF document seamlessly and efficiently. It is built in the way that a large PDF document can be opened in minimal time and all their pages can be accessed spontaneously.
SfPdfViewer provides option to navigate to the desired pages and bookmarks within the document. Also it allows zooming and customization of features being displayed, such as scroll head, page scroll status and navigation dialog.
This example demonstrates how to load the PDF document from AssetBundle.
