fix: reload posts when the parent widget has rebuilt on the timeline screen

This way if the service passed to us is changed we'll update our posts from it instead
of keeping the ones from the previous service.

+In the `timeline` collection all posts will be stored. In the `users` collection all users will be stored.
+In the `users` collection you should add your users data.

 ## How to use
-To use the module within your Flutter-application you should add the following code to the build-method of a chosen widget.
+To use the userstory add the following code somewhere in your widget tree:
+
+````
+timeLineNavigatorUserStory(TimelineUserStoryConfiguration, context),
+````
+
+
+Or create your own routing using the Screens:
+To add the `TimelineScreen` add the following code:
+
+````
+TimelineScreen(
+  userId:  currentUserId,
+  service: timelineService,
+  options: timelineOptions,
+),
+````
+
+`TimelineScreen` is supplied with a standard `TimelinePostScreen` which opens the detail page of the selected post. Needed parameter like `TimelineService` and `TimelineOptions` will be the same as the ones supplied to the `TimelineScreen`.
+
+The standard `TimelinePostScreen` can be overridden by defining `onPostTap` as shown below.
+
+```
+TimelineScreen(
+  userId:  currentUserId,
+  service: timelineService,
+  options: timelineOptions,
+  onPostTap: (tappedPost) {
+    await Navigator.push(
+      context,
+      MaterialPageRoute(
+        builder: (context) => Scaffold(
+          body: TimelinePostScreen(
+            userId:  currentUserId,
+            service: timelineService,
+            options: timelineOptions,
+            post: post,
+            onPostDelete: () {
+             service.deletePost(post);
+            },
+          ),
+        ),
+      ),
+    );
+  },
+),
+```
+
+A standard post creation is provided named: `TimelinePostCreationScreen`. Routing to this has to be done manually.
+
+```
+TimelinePostCreationScreen(
+  postCategory: selectedCategory,
+  userId: currentUserId,
+  service: timelineService,
+  options: timelineOptions,
+  onPostCreated: (post) {
+    Navigator.of(context).pop();
+  },
+),
+```
+
+You can choose to show an overview of the post before actually posting it using the `enablePostOverviewScreen` config setting.
+
+
+The `TimelineOptions` has its own parameters, as specified below:
+
+| Parameter | Explanation |
