[2.8.0 pdfx] Flickering/Flashing of PDF Viewer on Page Load

[LouisHeinrichAS]

Describe the bug
When using the PdfViewPinch widget to display a PDF document (using Uint8List), there is a noticeable flickering or flashing effect when scrolling through the document. This occurs even after the page is fully loaded, causing a disruptive user experience when displaying on the web.

To Reproduce
Load a PDF document using PdfViewPinch with a PdfControllerPinch to manage the document.
Observe the behavior during the page load. The PDF viewer flickers or flashes when displayed on web.

FutureOr<Uint8List> data; // bodyBytes from http response

final pdfPinchController = PdfControllerPinch(
  document: PdfDocument.openData(data),
);

PdfViewPinch(
  controller: pdfPinchController,
  builders: PdfViewPinchBuilders<DefaultBuilderOptions>(
    options: const DefaultBuilderOptions(),
    documentLoaderBuilder: (_) => const Center(child: CircularProgressIndicator()),
    pageLoaderBuilder: (_) => const Center(child: CircularProgressIndicator()),
    errorBuilder: (_, error) {
      return const Center(child: Text(Strings.fileViewError));
    },
  ),
);

Expected behavior
Once the page is fully loaded, it should remain stable without any flickering or flashing when scrolling through the document.

The same. It's a blocker for me. But the library doesn't seem to be supported.

I'm also facing the same issue, Does anyone have a fix?
