Thus, the Flutter application is itself a widget. In the above example, we can see that all the components are widgets that contain child widgets. Here, we are going to explain the example with the following diagram. We can understand it from the hello world example created in the previous section. This feature helps you to create a complex user interface very easily. It means the app is the top-level widget, and its UI is build using one or more children widgets, which again includes sub child widgets. In Flutter, the application is itself a widget that contains many sub widgets. The widgets are similar to the React components.

Widget in the Flutter is basically a user interface component that affects and controls the view and interface of the app. In Flutter, everything is a widget, which is the core concept of this framework. These libraries are written in Dart language. It contains all the required packages for the basic building blocks of writing a Flutter application. It takes Google's open-source graphics library, Skia, to render low-level graphics. It implements Flutter core libraries that include animation and graphics, file and network I/O, plugin architecture, accessibility support, and a dart runtime for developing, compiling, and running Flutter applications.

It is a portable runtime for high-quality mobile apps and primarily based on the C++ language. The Flutter architecture mainly comprises of four components. Rather, it would beīetter to add a listener to the TabController that updates theĪssignment TabController(vsync: tickerProvider, length: tabCount).addListener(() )Ĭreates a visual scaffold for Material Design widgets.In this section, we are going to discuss the architecture of the Flutter framework. View a scaffold with a differently titled AppBar.
