[Android only] App crashes on PlattformException

[GitHelge]

Describe the bug When I try to check the error handling for non-PDF files, I get a PlatformException (PlatformException(RENDER_ERROR, Invalid PDF format, null, null)) on iOS when I load a PNG file. This is totally fine and expected as I can handle the error with the errorBuilder.

On Android, the same test-file causes the app to crash in the simulator, as well as on device:

To Reproduce

Steps to reproduce the behavior:

Use this code snippet on a page to load e.g. a PNG file:

PdfView(
  scrollDirection: Axis.vertical,
  controller: PdfController(
    document: PdfDocument.openFile(_file!.path),
  ),
  builders: PdfViewBuilders<DefaultBuilderOptions>(
    options: const DefaultBuilderOptions(),
    errorBuilder: (context, error) {
      // On iOS, this is reached. On Android, the App Crashes.
      Logger('PDFView').severe(
        'PdfView loading failed',
        error,
        StackTrace.current,
      );
      return Center(
        child: Text("Some Error"),
      );
    },
  ),
)

Expected behavior I would expect the same error-handling on Android and iOS.
