title: flutter direct share to whatsapp and telegram in android and ios
body: <p>I want share a pdf file from flutter, directly to whatsapp and telegram in ios and android</p>
  <p>Note 1: Flutter <a href="https://pub.dev/packages/share_plus" rel="nofollow noreferrer">share_plus</a> package can't do this, I want directly share to whatsapp and telegram without device native appchooser dialog for share.</p>
  <p>Note 2: I don't want use universal links, because I can't sent file with this method, universal links only supports text.</p>
  <p>Is there any package for this purpose?
  If there isn't, How can I write native code for this in ios and android?</p>
