title: How to view files(docx, ppt, xlsx, etc.) from my project’s assets in flutter?
body: <p>Im working on a flutter app that needs to view document files. Is there a way to open or view document files from my assets?</p>
  
  <p><code>FlutterPdfViewer.loadAsset(filepath)</code> works fine but <code>OpenFile.open(filepath)</code> only works with files within the phone’s storage. 
  I can’t find any packages to view other file types besides pdf files from my project’s assets. Are there other ways? I hope you can help me.</p>
