Question: I am developing an app that has a bottomnavitaionbar with five pages. I use getx. In first page, i am listing data. My problem is that, when i changed data(first page in bottomnavigationbar) manually from database and thn i pass over pages, came back to first page i could not see changes.

Controller;

```
class ExploreController extends GetxController {
  var isLoading = true.obs;
  var articleList = List<ExploreModel>().obs;

  @override
  void onInit() {
    fetchArticles();
    super.onInit();
  }

  void fetchArticles() async {
    try {
      isLoading(true);
      var articles = await ApiService.fetchArticles();
      if (articles != null) {
        //articleList.clear();
        articleList.assignAll(articles);
      }
    } finally {
      isLoading(false);
    }
    update();
  }
}

```

and my UI;

```
body: SafeArea(
        child: Column(
        children: <Widget>[
          Header(),
          Expanded(
            child: GetX<ExploreController>(builder: (exploreController) {
              if (exploreController.isLoading.value) {
                return Center(
                  child: SpinKitChasingDots(
                      color: Colors.deepPurple[600], size: 40),
                );
              }
              return ListView.separated(
                padding: EdgeInsets.all(12),
                itemCount: exploreController.articleList.length,
                separatorBuilder: (BuildContext context, int index) {

```

Answer: 
thanks to @Baker for the right answer. However, if you have a list and in viewModel and want to update that list, just use the `list.refresh()` when the list updated

```
RxList<Models> myList = <Models>[].obs;

```

when add or insert data act like this:

```
myList.add(newItem);
myList.refresh();

```
If you change the value in the database 'manually', you need a STREAM to listen to the change on the database.
You can't do:

```
var articles = await ApiService.fetchArticles();

```

You need to do something like this:

```
var articles = await ApiService.listenToArticlesSnapshot();

```

The way you explained is like if you need the data to refresh after navigating to another page and clicking on a button, then navigating to first page (GetBuilder) OR automatically adds data from the within the first page (Obx). But your case is simple, just retrieve the articles SNAPSHOT, then in the controller onInit, subscribe to the snapshot with the bindStream method, and eventually use the function ever() to react to any change in the observable articleList.
Something like this:
