Unable to open pdf file in flutter

I want to open a pdf file using open_file package.

OpenFile.open('/data/user/0/xxx/app_flutter/ABC-2745.pdf20200818-5566-1byemw9.pdf');

Error

E/flutter ( 9713): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PlatformException(error, Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.PackageItemInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference, null)

Edit

I get the url from server, and store it in local

generatePDF(dynamic value) async {
    print(value);
    final filename = value.substring(value.lastIndexOf("/") + 1);
    var request = await HttpClient().getUrl(Uri.parse(value));
    var response = await request.close();
    var bytes = await consolidateHttpClientResponseBytes(response);
    String dir = (await getApplicationDocumentsDirectory()).path;
    File file = new File('$dir/$filename.pdf');
    await file.writeAsBytes(bytes);
    print(file.path);
    try {
      OpenFile.open(file.path);
    } catch (e) {
      print(e.toString());
    }
  }

Output
