The official Flutter documentation can be found here.

Flutter – type 'List<dynamic' is not a subtype of type <List<String> in type cast

I am tryiong to display a list of events a user has registered for in a flutter app but i keep getting this error even though I am following the tuorial closely. I believe the error might be in the following lines but I have checked multiple times but havent gotten a fix.

        ref.watch(userEventsProvider).when(
              data: (events) => Expanded(
                child: ListView.builder(
                  itemCount: events.length,
                  itemBuilder: (BuildContext context, int index) {
                    final event = events[index];
                    return ListTile(
                      leading: CircleAvatar(
                        backgroundImage: NetworkImage(event.images),
                      ),
                      title: Text('/r${event.name}'),
                      onTap: () {},
                    );
                  },
                ),
              ),
              error: (error, stackTrace) => ErrorText(
                error: error.toString(),
              ),
              loading: () => const Loader(),
            ),

I have tried following the tutorial but theres seems to be no fix.

    it seems like the issue might be with the event.images field. it’s actually a list of dynamic objects.

    CircleAvatar(
  backgroundImage: NetworkImage(event.images[index]), // Corrected line
),

    Replace index with the appropriate index
