Tried this but no luck:

  @override
  _FirstPageState createState() => _FirstPageState();
}

class _FirstPageState extends State<FirstPage> {

  StreamController<Widget> overlayController =
  StreamController<Widget>.broadcast();

  @override
  void dispose() {
    overlayController.close();
    super.dispose();
  }

Hello, while developing I am used to use the linux version of my app.

While the swipe image gallery works perfectly on android, I noticed that in linux it is malfunctioning.

Symptoms upon opening:

• the first image of the gallery opens as it should
• swipe does not work, the feeling is as if the gallery froze
• dragging from the very top (or bottom) in the opposite direction closes the gallery
• there is no way though, to see the other images

Do you experience the same issue.

Thanks for the nice library.

Hi again, I had to close my old PR because i accidentially pushed something i didnt intent and i couldnt reopen since i force pushed the branch... Please take a look at the code, if u have time. Greetings

Hi, kinda liked your library. The logic was easy to follow and it seems to work quite well so good work.

I added an animation for the image to center it again, when the dismissal threshold is not reached.

The dependecy changes in for gradle where kinda necessary to build the example. Hope its not a problem.

Greetings
