Riverpod future provider not rebuilding ui - flutter

Question

My problem is that when I run the app, the data doesn't show up on the UI. The code below is rendered under a bottom navigation bar format which is a stateful widget. To my knowledge the below code should work (show data on the initial running of app).
The code works but the data is only shown when I press hot reload. I've tried everything that I know but it still doesn't show data when I start the app.
final imageControllerProvider = Provider((ref) {
return ImageController();
});
final mainScreenImages = FutureProvider<List<String>>((ref) async {
List<String> list = [];
list = await ref.watch(imageControllerProvider).getImages();
return list;
});
class ImageController{
Future<List<String>> getImages() async {
List<String> imageUrls = [];
try {
final Reference reference = _storage.ref().child("weed/");
reference.listAll().then((value) {
for (var element in value.items) {
element.getDownloadURL().then((e) => imageUrls.add(e));
}
});
} catch (e) {
print(e);
}
return imageUrls;
}
}
class GenerateImages extends ConsumerWidget {
const GenerateImages({super.key});
#override
Widget build(BuildContext context, WidgetRef ref) {
final imageList = ref.watch(mainScreenImages);
final double screenwidth = MediaQuery.of(context).size.width;
final double screenheight = MediaQuery.of(context).size.height;
return imageList.when(data: (data) {
return Text('$data');
}, error: (_, __) {
return const Scaffold(
body: Center(
child: Text("OOPS"),
),
);
}, loading: () {
return const Center(child: const CircularProgressIndicator());
});
}
}

I think the problem is because in getImages() you are not awaiting the results instead you are using the then() handler to register callbacks. Replace your getImages() function with this and try.
Future<List<String>> getImages() async {
List<String> imageUrls = [];
try {
final Reference reference = _storage.ref().child("weed/");
final value = await reference.listAll();
for (var element in value.items) {
final url = await element.getDownloadURL();
imageUrls.add(url);
}
} catch (e) {
print(e);
}
return imageUrls;
}
}
