What you'd like to happen

Provide an onTap callback in the File Previewer widget. It will be useful in case of viewing file after uploading.

Usecase:
lets assume a user upload multiple files (pdf). As its not possible to preview pdf file we can provide a callback where we get a Platform file as argument. And using callback we can open file using external package.
