title: Why is open_file in flutter not opening any files in my app?
body: <p>I'm working on a mobile app--I'm using flutter and it needs to view documents in my assets. I used the pdfviewer and it works perfectly fine. But with openfile, it does not.</p>
  
  <p>I used the flutter package,
  <a href="https://pub.dartlang.org/packages/flutter_pdf_viewer" rel="nofollow noreferrer">https://pub.dartlang.org/packages/flutter_pdf_viewer</a> and it opens the pdf file but with this package, <a href="https://pub.dartlang.org/packages/open_file" rel="nofollow noreferrer">https://pub.dartlang.org/packages/open_file</a> it won't open any files. 
  This is how i call them:</p>
  
  <pre><code>onPressed: () =&gt; FlutterPdfViewer.loadAsset("assets/files/sample.pdf"),
  
  onPressed: () =&gt; OpenFile.open('assets/files/samplefile.docx'),
  </code></pre>
  
  <p>I don't know any more methods to open files in flutter. Am I using the open_file the wrong way? I hope you can help me figure this out.</p>
