While Dart is at its core an object-oriented programming language, that doesn’t mean that you’re stuck only with that paradigm. In fact, Dart is something called a multi-paradigm language! Functional programming (FP) makes your code easier to test and reuse and also makes it less error-prone.
With Dart, it’s easy to start introducing practical functional concepts into your code in a reasonable amount. This way, you reap the benefits of FP while not confusing others (and yourself) with how your Dart code is written.

    Very interesting presentation of an architecture. I have a question for you. In functional programming, you usually have an Either and a Try defined as Try<T> = Either<Error. T>. A Future<T> can be seen as an asynchronous version of Try<T>. Why don't you use the Future error response to handle errors and instead adds an additional layer of wrapping the error inside an Either inside the Future? Is just to differentiate "Business" errors from "infrastructure" errors?

  • @aloussase
    @aloussase Před 2 měsíci

    I wouldnt have created an interface for use cases because no one is really benefiting from that and it makes the code uglier because the different use cases are sufficiently different to make it awkward to use the same interface. Otherwise great video!

  • @aloussase
    @aloussase Před 2 měsíci

    The use case interface would be neater with something like variadic template parameters for the params type

    Great video @ResoCoder Suppose there is some variable like bool , string or any variable that can change UI like isSaved Something like that so if we need to handle them how we can Like in Getx we can declare in controller file but in this structure how we can manage As u said in bloc there will be only less logic like calling apiRepo/use case so can you explain that one? It will be great. Also more question on any sdk implementation like firebase services or suppose we are using any ChatSdk so how do we manage that in clean architecture

    I follow you, I try to adjust to The code is the current version. Your teaching is excellent. But I encountered a problem. The argument type 'Null' can't be assigned to the parameter type 'int'. So I tried to fix it. when(mockNumberTriviaRepository.getConcreteNumberTrivia(any<int>())) .thenAnswer((_) async => const Right(tNumberTrivia)); Then I ran into another problem. An expression whose value is always 'null' can't be dereferenced. Try changing the type of the expression. Who can help me?

    Somehow the control bar in v1.7.5 is cluttered. There is no padding between progress bar and controls, so much so that the volume icon is 20% cut from the bottom. The experience is so bad that now I'm building my own simple control bar and using the VideoProgressIndicator class of video_player package as progress bar.
