How to load images from a folder in firebase storage and use it elsewhere

Question

I am trying to load images from a folder in firebase storage and the code is giving me this error {type 'Future' is not a subtype of type 'String'} , I don't even know if this code achieves my purpose

class FireStorageService extends ChangeNotifier{
  FireStorageService();
  final storage = FirebaseStorage.instance;
  static Future<dynamic> loadImage(String image) async{
    return await storage.ref('folder5/$image').getDownloadURL();
  }
}
Future<Widget> getImage() async {
  final url = await FireStorageService.loadImage('1.jpg');
  return Image.network(url);
}

Have a look at this [stackoverflow thread](https://stackoverflow.com/questions/50877398/flutter-load-image-from-firebase-storage) — Priyashree Bhadra, Nov 01 '21 at 09:21

Return Future<String> from loadImage function:

class FireStorageService extends ChangeNotifier{
  FireStorageService();
  
  static Future<String> loadImage(String image) async {
    return await FirebaseStorage.instance.ref('folder5/$image').getDownloadURL();
  }
}

Future<Widget> getImage() async {
  final url = await FireStorageService.loadImage('1.jpg');
  return Image.network(url);
}
