In cases where one widget needed to inform of a user action in another widget, I passed around callbacks. I used state that was bound to a stateful widget and it did not have to be shared between many different components. The application itself is not very complex and I did not have to use any of the state solutions listed above. In this Settings screen, the user can make some application level configurations. ![]() You will know when that is not enough anymore once you try to develop a component and use those two options and figure out you need something else to make things work.Īt some point in developing my application, I decided I wanted to have a Settings screen. It might be just fine for you to manage state with stateful widgets and setState. Now, before you keep on reading, it is important to understand that, depending on the logic and complexity of your application, you might not need one of the aforementioned solutions. To give you a better understanding of what I was talking about earlier.The list above is taken directly from the Flutter documentation for state management and I wanted to show it to you for two reasons: □ H-o-l-y crap! Can you believe that list? Ready to SetState? Flutter State Backgroundįor the unassuming, below is a list of all the state solutions offered by the Flutter team (as of April 2022): We will go over several basic fundamental concepts in state management in Flutter and I’ll be working with a real use case example to make things as clear as possible (none of that counter application nonsense □). Taking it on alone can feel overwhelming, so I’m hoping that this article provides a compass for you when you are in need. Or you can come face to face with the monolith that is Flutter state management. ![]() When you reach that point, you can try and hack a solution that provides you with the desired functionality, but it will probably not follow the correct paradigms. But nothing beats getting your hands dirty and trying things out by yourself.Īfter much tribulation and my fair share of trial and error, I’m beginning to see the light in my understanding of managing state in Flutter based applications.Īs Flutter grows in popularity and as your application can become more and more complex, you will come to a point where creating stateful widgets isn’t going to cut it. ![]() Like you, I’ve looked over them and I have tried to grasp this intangible concept in Flutter. There are numerous articles that try to explain this, but they usually cover one specific solution and provide a very minimal example. If you are reading this, then you are probably aware of the many ways you can manage state in Flutter. But in Flutter, things are a bit different. You might be familiar with the model-view-viewmodel (MVVM) pattern, where the ViewModel is the one responsible for a view’s state. Managing state is something most developers need to deal with when working on applications.
