How can I show or download pdf files inside a Flutter_webview?

I want to open or download a PDF-File inside my webview. I tried to enableFilesURl inside the webview community version but it doesn´t work.

Best regards Falk

Future<File> createFileOfPdfUrl({String urlP = ''}) async {
                            final url = urlP;
                            String filename = '${DateTime.now().microsecondsSinceEpoch}';
                            var request = await HttpClient()?.getUrl(Uri.parse(url));
                            var response = await request.close();
                            var bytes = await consolidateHttpClientResponseBytes(response);
                            String dir = (await getApplicationDocumentsDirectory()).path;

                            File file = new File('$dir/$filename');
                            await file.writeAsBytes(bytes);
                            return file;
                          }
