如何在 Flutter 中更改 PDF 视图背景颜色

Question

I'm working on Flutter project and I'm trying to change the PDF view background color to white but some reason the color is not apply even when I wrap with other widget so I would be really appreciated If I can get any help or suggestion.

Basically I want this to be white too. I'm not sure it's possible but it would be awesome if I can get any suggestion.

      body: SfPdfViewer.asset(
        'assets/data/songs.pdf',
        initialZoomLevel: 3.0,
        enableDoubleTapZooming: true,
        initialScrollOffset: Offset.fromDirection(10),
        controller: _pdfViewerController,
        pageLayoutMode: PdfPageLayoutMode.single,
        pageSpacing: 4,
        canShowScrollHead: false,
        onDocumentLoaded: (details) {
          _pdfViewerController.jumpToPage(widget.pageNumber);
        },
      ),

Answer 1

final GlobalKey<SfPdfViewerState> _pdfViewerKey = GlobalKey();

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
  title: Text('Syncfusion Flutter PdfViewer'),
  actions: <Widget>[
    IconButton(
      icon: Icon(
        Icons. bookmark,
        color: Colors.white,
      ),
      onPressed: () {
        _pdfViewerKey.currentState?.openBookmarkView();
      },
    ),
  ],
),
body: SfPdfViewer.network(
  'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
  key: _pdfViewerKey,
),
);
}

you can use scaffold widget and give background color more information
