Probably you have the wrong name in one of the fields in the database.

exactly the same

[awaik]

Can you send me the code, I'll check it.
Please double-check that you have Maps - in the case of Array instead of map you will have this error.

i copied your code and i was just testing

class Stories extends StatelessWidget {
   Stories({Key? key}) : super(key: key);

 static const String collectionDbName = 'stories';

final controller = Get.put(ProfilePageScreenController());

  final CollectionReference dbInstance =
  FirebaseFirestore.instance.collection(collectionDbName);

  @override
  Widget build(BuildContext context) {


    return FlutterInstagramStories(
      collectionDbName: collectionDbName,
      showTitleOnIcon:true,
      backFromStories: () {
        controller.backFromStoriesAlert(context);
      },
      iconTextStyle: const TextStyle(

This is definetaly the data structure.
Please check maps, arrays one more time.
I've updated example - it works, so the reason is in the database.

[Ozgur-Abi]

Did you have any success solving the issue? I have the same database schema but although i can see previews, when i try to view stories I get this error

[awaik]

Please check arrays and maps as on the screenshots upwards.

I fixed it with this suggestion,
#16
And created a fork of it https://github.com/Ozgur-Abi/flutter_instagram_stories_fixed.

However, video stories still don't work, on both your version and my fork. I tried it with both on my database and your database and example code. Video shows as loading but never loads.

[awaik]

Can you please make a video with database - when you point a mouse it displays field type.
In this case I will know for sure that the data structure is ok and help to fix it.

uncomment setstate() - inside story_video.dart - code snippet --- playerController!.initialize().then((v) {
setState(() {});
widget.storyController!.play();
});
