When writting testing code of usecases, we should test Failure case?

[@dbestech]

Yes, when writing testing code for use cases in Flutter, it is essential to test failure cases. Testing failure cases ensures that your application handles errors gracefully and provides the correct responses or actions when something goes wrong

Do you think is it good in maintenance and performance during generating models with Freezed package? Is it worth it to use that package, or a better approach is to write everything by my own, because it is easier to debug? I am thinking about complex app with a lot of models.

[@dbestech]

Don’t use freezed with clean architecture and its anti pattern. At the same time it increases complexity

[@Migolek12]

​@@dbestechyeah I guessed that in one hand it allows you to create models faster, but on the other hand you lose control over the models. As you are using BLoC for state management, can you say something about Riverpod? I am really confused which one will be better to this approach, with DDD and clean architecture.

I didn't encountered any problem with your video. The problem is specific with my case. i use a model with multiple fields and when a user register he just fill some of those fields. So when i retreive data, decode it as json and try to convert it as a model, i got the error: expected a 'String' but got a 'null' value because there are fields that the user have to complete after sign in.

Hey dbestech , in my last course on udemy the elearn course , we didnt use getIt dependecy injection and this domain thing , is this architecture more desired or the one we used in the elearn app 😅 even i feel more comfy with the old on in elearn , i feel this could be interesting too , and is singleton opposite if DI ? HOPE you will answer

[@wolfgangschneider3743]

Your explanation of object equality in the dartcode example is not entirely accurate. The reason they evaluate to true in the first run is the fact that you declared them with const, which makes the compiler use the same copy in both cases. If you'd use final instead, the result would have been false, since 2 real copies are generated then. So the reason it gave back false in the second run is actually the final keyword, not the DateTime member. It forces you to use final, but it's equality comparator is not the reason.

[@dbestech]

Thank you for your clarification. You are correct that the use of const in Dart leads to the compiler reusing the same instance, which results in object equality (==) evaluating to true. When final is used, two separate instances are created, leading to the equality comparison evaluating to false. Here’s a revised explanation incorporating your points: In Dart, when objects are declared with const, the compiler optimizes by reusing the same instance for identical constants. This is why const objects compare as equal using ==, as they refer to the same memory location. For example: const a = SomeClass(); const b = SomeClass(); print(a == b); // true, because a and b refer to the same instance When final is used instead of const, each variable holds a separate instance of the object, even if they are identical in content. This results in == evaluating to false, as the objects occupy different memory locations. For instance: final a = SomeClass(); final b = SomeClass(); print(a == b); // false, because a and b are different instances Regarding the second part of your point, the presence of a DateTime member in the class enforces the use of final instead of const, since DateTime is not a compile-time constant. Thus, the resulting objects are not the same instance, which explains why the equality comparison evaluates to false. Thank you for pointing out these nuances in Dart’s handling of object equality with const and final.
