Hi @Nialixus, At present, Syncfusion Flutter PDF Viewer does not have the built-in support to customize the document loading indicator and page loading indicator. We don't have any immediate plans to implement this support. At the planning stage of every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know here when this feature implementation is started in the future. The document loading indicator can be customized at the sample level using the code below,
class _HomePage extends State<HomePage> {
final GlobalKey<SfPdfViewerState> _pdfViewerKey = GlobalKey();
bool _isDocumentLoaded = false;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Syncfusion Flutter PDF Viewer')),
body: Stack(
children: [
SfPdfViewer.network(
'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
key: _pdfViewerKey,
onDocumentLoaded: (_) => setState(() => _isDocumentLoaded = true),
),
if (!_isDocumentLoaded) // Show the custom loading indicator
Container(
color: Colors.white,
child: const Center(child: CircularProgressIndicator()),
),
],
),
);
}
}Regards, |

page loading indicator in [SfPdfViewer].
Defaults to
