This consists in the usage of external storage using Firebase Storage. The first identification is Firebase Storage for images, which are essential for the features in the app. It used Google Cloud Storage buckets in order to save the files. However, these needs to be updated since the storageBucket has the path to 2018 photos. It also uses Firebase storage for the real time photo page. This technique wasn´t thought well but works since images aren´t updated.

The first caching structure identified consists in flutter_cache_manager. In this case, it is used to download and cache files in the cache directory of the app. Also, it uses cached_network_image since it is necessary to handle storage of user´s pictures of weekly Trinity College’s events. However, it uses a GitHub repository version as it is shown on figure. This can be a bad strategy since GitHub´s code is not public and cannot have the latest version which can cause troubles between the dependencies in future occasion. Also, this situation makes that users that has the code cannot execute the app because the repository is on other classes of the project.

When the users try to access to any of the social networks of the Trinity Orientation Week through the information section in the helpful resources area where there are their icons (like Facebook, Twitter, and Instagram), the application redirects them to another view while it finds a connectivity problem. So, we see that the application didn’t check the connectivity before redirecting to the view.

One way that occurs to us that this anti-pattern could be solved would be if there is a functionality that requires internet, and there is none, the user should be warned that they require an internet connection, and they don’t have one.

When the users try to access to the Toronto Transit Commission (TTC) website through the information section in the helpful resources area where there is its icon, in a no-connection environment, the application crashes showing them a black screen that to solve it they have to close and reopen the application, as we can see on figure 3. So, we see that the user invokes an action related to a connectivity process, but the reason for the behavior is unclear.

When the users go to the information section, they can see that in ‘questions’ part doesn’t’ evidence questions on the information section and it doesn’t give them an informative message about the situation. So, we can see that there is an error, but the users cannot know which one is since it just shows an exception without explanation instead of a question or even the clear error.

When the users try to access the map section when they don’t have internet connection and go to ‘buildings’ part and select one from the list that presents them, the application sends them to a screen where the building and its location within the Trinity College campus should be shown, but absolutely nothing is displayed.

One way that occurs to us that this anti-pattern could be solved would be to display a warning or pop-up message that notifies the user that there are connection problems and at this moment this functionality isn’t available.
