Description

In this final part of this Flutter video tutorial series, we finish our application by adding a Tab Controller and some Tabs as well as a favorites page. We also refactor the old code in a way that makes it much more efficient for our new layout. Through this application, we also explore how we can reduce exceptions including exceptions related to reading and writing from our SQLite database from multiple places in our application.

The Tab widget in Flutter allows us to create a simple routing solution with built-in animations and routes. This is a fairly elegant solution for an application that contains only a few static pages like in this movie searcher application. Because we only have two main pages in our application, we can define that we only need two tabs and then associate our custom widgets with these tabs. This also allows us to justify refactoring all of our main stateful widgets into a single folder.

We refactor our Database so that it is only being instantiated in our main Database class. In this way, we create a singleton object that can provide the data to all of the branches of our application. The we also add read capabilities to our database so that we can fetch the movies out of it and present them onto our favorites tab. This capability also allows us to maintain the favored state of each of the movie extension tiles on our homepage.
