How to open pdf file if it already exist in device in flutter?

var tempDir = await getTemporaryDirectory();
String fullPath = "${tempDir.path}/boo2.pdf'";
print('full path $fullPath');    
File file = File(fullPath);
if (await file.exists() && Platform.isAndroid) 
   {
    
    } else {
          download2(dio, imgUrl, fullPath);
            }

Above code is used to download pdf file in flutter. If file exist in device then it should directly open it. and if it is not then it should download. Now the problem is I dont know how to open exist pdf.

    Most simple solution would be to use open_filex

    import 'package:open_filex/open_filex.dart';

OpenFilex.open(fullPath);
