Designing Information Architecture

The Flutter mechanism for passing around dependencies through the tree is called InheritedWidget. You have certainly used it in your Flutter apps, even if you haven’t written one explicitly. Let’s take a look at what InheritedWidget is and how it can help us on our state management journey in this excerpt from Daria Orlova, Esra Kadah, and Jaime Blasco’s Flutter Design Patterns and Best Practices.

As you know, in Flutter, everything is a widget. So far, we have discussed various UI-related building widgets, such as Stateless, Stateful, and Render, as well as their descendants. However, because these widgets are organized in a tree data structure, it is possible to perform various manipulations with it, such as a tree traversal. This capability is useful when we need to not only render static UI but also pass around shared data.

The Flutter framework includes a widget specifically for this purpose: InheritedWidget. It is the last of the fundamental Flutter widgets. If we examine the framework.dart class and search for an abstract class, we will find only 25 instances in the entire file (as of Flutter 3.10). All of these are in some way related to Stateless, Stateful, Render, or Inherited.

So, let's take a look at the source code of InheritedWidget:

abstract class InheritedWidget extends ProxyWidget {

const InheritedWidget({ super.key, required super.child });

@override

InheritedElement createElement() => InheritedElement(this);

@protected

bool updateShouldNotify(covariant InheritedWidget oldWidget);

In the preceding code, take note of the following:

But how can we inherit from this widget and what kind of data may we possibly want to pass around? Read more in Flutter Design Patterns and Best Practices to find out.
