This issue can be fixed by decomposing the ScopedModel into multiple models so you get finer-grained dependencies. This might raise a performance issue, depending on how many ScopedModelDescendants a model has, as they’re rebuilt when there’s an update. In addition, it also rebuilds all of the children that use the model when the model is updated. It allows you to easily pass a data Model from a parent Widget down to its descendants. Scoped Model: This is an external package built on top of InheritedWidget and it offers a slightly better way to access, update and mutate state. The downside of using the InheritedWidget base class is that your state is final and this raises a problem if you want to mutate your state. Inherited Widget: It allows you propagate data to its child widgets and the widgets are rebuilt whenever there is a change in the app’s state. State management in Flutter can be achieved in a few different ways: In this article, we’ll see how to handle state in Flutter using the BLoC pattern.

These widgets will most likely need to share application state with each other. As you start composing these widgets to create your awesome app, you’ll end up with a tree of deeply nested widgets. In Flutter, all UI components are widgets.

It is important that state management is handled efficiently, so as to avoid accruing technical debt, especially as your application grows and becomes more complex. Flutter is Google’s awesome framework for crafting high-quality applications for Android and iOS.Īs with building almost any application, there’s always the need to handle application state. Last year, I picked up Flutter and I must say it has been an awesome journey so far.
