title: Launching custom URL scheme in Flutter
body: <p>I'm trying to implement <a href="https://developers.facebook.com/docs/instagram/sharing-to-stories" rel="nofollow noreferrer">this</a> functionality in Flutter. The android side is easy to mimic using the <a href="https://pub.dev/packages/android_intent" rel="nofollow noreferrer">android_intent</a> package, however I've yet to find a way of launching custom URL schemes in Flutter. There are packages that allow custom URL schemes to be accepted in the app, however I don't think they can be used in my case (<a href="https://pub.dev/packages/uni_links" rel="nofollow noreferrer">uni_links</a>).</p>
  
  <p>I'm aware that I could use platform channels however I would prefer to keep my code all in Dart. Thanks</p>
