How to render PDF pages using PDFium on Android?

5 Sep 20251 minute to read

The Syncfusion® Flutter PDF Viewer allows users to render PDF pages using the PDFium library on Android devices running API levels below 35 through an optional package, syncfusion_pdfviewer_android.

This optional package significantly enhances the loading performance of large password-protected PDF files on Android devices running API levels below 35, with performance improvements of up to approximately 13 times faster.

To render PDF pages using PDFium on Android devices running API levels below 35, add the syncfusion_pdfviewer_android dependency in the pubspec.yaml file.
