My Movies

A Flutter app showcasing a list of popular movies from MovieDB.

Here is a quick video of the app:

So the series "Architect your Flutter project using BLoC pattern" is complete. I have shown you what it takes to architect a Flutter app from the ground up. I have covered the following important topics in the series:

• Repository and BLoC pattern

• Separating UI and business logic

• Dependency Injection

• Unit and Integration testing

Here are the links of all the articles that were part of the series:

Part 1: https://medium.com/flutterpub/architecting-your-flutter-project-bd04e144a8f1

Part 2: https://medium.com/flutterpub/architect-your-flutter-project-using-bloc-pattern-part-2-d8dd1eca9ba5

Part 3: https://blog.usejournal.com/compile-time-dependency-injection-in-flutter-95bb190b4a71

Part 4: https://medium.com/@sagarsuri56/integration-and-unit-testing-in-flutter-f08e4bd961d5

Let me know what are the other topics you would like me to write on.

mymovies's Issues

Single instance vs Scoped instance

What's the difference between exposing BLoC classes as single instance vs scoped instance? is it just a way to help structuring the code or has an effect on the app performance?

Can't build because this code is OLD. :(

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
Android resource linking failed
  C:\Users\****\.gradle\caches\transforms-2\files-2.1\aa01b3476390fc3ee49dd14944aa77f9\res\values\values.xml:192:5-228:25: AAPT: error: resource android:attr/fontVariationSettings not found.

  C:\Users\****\.gradle\caches\transforms-2\files-2.1\aa01b3476390fc3ee49dd14944aa77f9\res\values\values.xml:192:5-228:25: AAPT: error: resource android:attr/ttcIndex not found.

  error: failed linking references.

And since I'm still pretty new to Flutter / DART, I have no clue how to fix that.

It seems like 'http' no longer works (?)

In my case, only the following method worked.
final _baseUrl = "https://api.themoviedb.org/3/movie";

how to load more data on scroll?

Thanks for this easy-to-follow code/article series on Flutter's BLOC pattern. After going through the code, I realized that there's no way we can load more data on scrolling to the bottom of the list. How do you think we can achieve it? Obviously, there's going to be Listview/gridview controller to listen to the scrolling events, but how to pass the page number to the Bloc class so that it can call the API (with new page number) again using the repository/provider classes?

Many thanks in advance!
