A widget is either stateful or stateless. Let’s see what exactly it means. A stateless widget is like a constant. I am learning Dart/flutter and trying to understand how Widgets system works and I found out some useful things, hope it helps you too. Both widgets differ in only one aspect which is the ability to reload the widget at runtime. Stateful 2. Actually There are 3 kind of widgets, not just 2. Stateful widget; Stateless widget; Inherited widget; Stateful Vs stateless Stateless Widget. If a widget can change—when a user interacts with it, for example—it’s stateful. they are immutable. In this article, I will show you what is the difference between Stateful and Stateless Widget.As you know in Flutter all the UI components are known as widgets. It is immutable. These states are mutable and can be changed multiple times in their lifetime. In the stateless widget, the build function is called only once which makes the UI of the screen. In this article, I will show you what is the difference between Stateful and Stateless Widget.As you know in Flutter all the UI components are known as widgets. So now that you understand State, you can see where the names Stateless and Stateful come from. The widget which contains the code for a single screen of the app can be just of two types —Stateless widgets do not require mutable state, i.e., it is In simple words, Stateless widgets cannot change their state during the runtime of the app, which means the widgets cannot be redrawn while the app is in action.The structure of a Stateless widget looks like this:So, let’s understand what is there in this small code snippet.If you want to redraw the Stateless Widget, then you will need to create a new instance of the widget.TIPS: You can quickly build a Stateless Widget in VS Code or Android Studio by using the shortcut “Stateful widgets have a mutable state, i.e., they are They are the widgets which can change their state multiple times and can be redrawn on to the screen any number of times while the app is in action.The structure of a Stateful widget looks like this:TIPS: You can quickly build a Stateful Widget in VS Code or Android Studio by using the shortcut “stf”.We have come to the end of this short article. The name of the stateless widget is MyApp which is being called from the The build function contains a container which is again a widget of Flutter inside which we will design the UI of the app. These concepts would be more clear if you do some projects on your own and get the feel of how the app handles the state.In my next, article we would focus on the pre-build Demo Flutter app (i.e., the If you do not want to miss my next article and the articles that I will be publishing in the future, please Sign Up to the There will be at least one article added to the blog every week.If you want to support me and want me to continue writing Flutter articles and building some interesting Flutter projects, please contribute to my Patreon page below: I hope you all have received a basic idea of Stateful and Stateless widgets and how do they differ from each other.

So now as we know what are these states lets dive directly into our main topic i.e what are these stateful and stateless widgets and how do they differ from one another.So let us see what this small code snippet tells us. The state of an app can very simply be defined as anything that exists in the memory of the app while the app is running. A stateless widget never changes. The widget which contains the code for a single screen of the app can be just of two types — 1.

StatelessLet’s discuss how do they differ.

As we all know the flutter app consists of widgets only, these are broadly classified into two types: Stateless Widget; Stateful Widget; Stateless Widget: Stateless widgets are the widgets that don’t change i.e. acknowledge that you have read and understood our By using our site, you In the stateless widget, the build function is called only once which makes the UI of the screen.So let us see what we have in this code snippet. This subtle difference plays a huge role in building interactive flutter applications. Its appearance and properties remain unchanged throughout the lifetime of the widget. Stateless means it has no state. The name of the Stateful Widget is MyApp which is called from the If you like GeeksforGeeks and would like to contribute, you can also write an article using Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below.Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. Stateful is full of state. Stateful Widgets: The widgets whose state can be altered once they are built are called stateful Widgets. If a widget is constant and does not change no matter what is done, then it does not have a State. This includes all the widgets that maintain the UI of the app including the buttons, text fonts, icons, animations, etc. As you might have guessed based on the topic of this post, each widget in flutter is either a Stateful Widget or a Stateless Widget.
