#Flutter provider code
I don't think that is necessarily bad practice as long as things are readable and everyone is on the same page.Īs to your question about the logic blurring in with the UI, I think one advantage of separating things more strictly is that it is easier to test things by mocking external dependencies.I'm trying to make a form with provider in order to separate my logic in my code but I'm struggling. Flutter Entertainment PLC closed £7.47 short of its 52-week high (£168.32), which the company achieved on April 11. You could also just do the same thing that those libraries do or create a comparable system of separating responsibilities with lower level libraries like provider, rxdart, getIt, and plain old dart. Riverpod is another popular one where it is more about different versions of the provider, and is probably closer to what you are doing now based on how you describe it. In this article, we will be building a sample app with one of the best state management packages for Flutter: Provider. What you choose to provide and how you provide it is where a lot do the differences come in with different approaches.īloc is one popular approach, and you will use BlocProvider just like Provider to instantiate and access the bloc instances. But I am looking to know the most common use case of providers. Provider is how you can provide access to some state structure to a certain scope. What is the use of provider in flutter Ask Question Asked 3 years, 8 months ago Modified 1 year, 4 months ago Viewed 5k times 5 Well, I am sort of new to Flutter, My question is why we use providers in Flutter, I know it is used for state management. (Considering it is sort of just an easier way to declare an InheritedWidget, that makes sense.) I think provider can be used for many different strategies, and seems basically like core flutter at this point. It will result in more files, but I like the separation into different files. If you want stronger separation of the presentation and logic layers, than BLoC is useful.

You can use Provider and it will be successful.

If you use VS Code, you will need the BLoC extensions and the Dart Data Class Generator to make life easier.Īny technique is possible. You will also need build_runner and chopper_generator. I was reluctant to use code generation at first, but it is nice after a few projects. I am also using chopper for the HTTP requests. BLoC already has more of a pre-defined structure, so it is easier to keep the separation of the business logic. Provider is easier at first, but requires more management of the team and likely more up-front architecture design. It provides a state management technique that is used for managing a piece of data around the app. We can test that the FutureProvider state first changes to AsyncValue. The provider package is an easy to use package which is basically a wrapper around the InheritedWidgets that makes it easier to use and manage. I switched from provider to BLoC flutter_bloc after using Provider for a year. To start, we can test the happy path of the jokesFutureProvider. If you want more opinions from people working on smaller projects than eBay (and also not as skilled as the eBay developers), I will give my opinion. In my opinion, the gold standard for this type explanation is the eBay Motors and State Management article.
