Listen to a new value of a bloc and generate a list of listened items - flutter

Question

I have this StreamSubscription field called followSubscribtion. It listens if there is a new follower and then calls populateFollower to load follower profile.
followsSubscription =
getBloc(context).followsHandler.stream.listen((value) async {
if (value.status == Status.success) {
await populateFollows();
}
});
});
populateFollows() async{
if (getBloc(context).followsModel.length > 0) {
for (var i = 0; i < getBloc(context).followsModel.length; i++) {
getBloc(context).loadFollowsProfile(getBloc(context).followsModel[i].userId);
break;
}
}
}
This works fine, But I want each profile that will be loaded to be added to a list, How do I do that?
loadFollowsProfile method
loadFollowsProfile(int id , List<UserProfileModel> profileList) {
getFollowsProfileHandler.addNetworkTransformerStream(
Network.getInstance().getUserProfile(id), (_) {
userProfileModelBloc = UserProfileModel.fromJson(_);
profileList.add(userProfileModelBloc);
return userProfileModelBloc;
});
}

You can do this by setting up loadFollowsProfile() to return a UserProfileModel, adding that to a list in the for loop of populateFollows(), and then returning that list from populateFollows().
List<ProfileObject> populateFollows() async{
List<ProfileObject> profileList = [];
if (getBloc(context).followsModel.length > 0) {
for (var i = 0; i < getBloc(context).followsModel.length; i++){
profileList.add(getBloc(context).loadFollowsProfile(
getBloc(context).followsModel[i].userId
));
break;
}
}
return profileList;
}
followsSubscription =
getBloc(context).followsHandler.stream.listen((value) async {
if (value.status == Status.success) {
profileList = await populateFollows();
}
});
});
