What is Flutter?
- Flutter is a open-source mobile UI framework that is created by Google. It allows us to develop a multi platforms application with one programming language(Dart) and one code-base. It uses own high-performance rendering engine to draw widgets and systems such as animation, gesture, and widgets.
What is the Difference between Stateless and Stateful widget?
- The Stateless widget does not require a mutable state. Stateless widgets are not dynamically changed whenever you update any value. For example, if you want to make a button or text whose title doesn't need to change dynamically, then you can create a separate widget for a button as a Stateless widget.
- The Stateful widget has a mutable state. It means, when you want to make something that you want to change dynamically according to how a user interacts with it, then you can use the Stateful widget. For example, if you want to change the background color of the app on the click of a button, you can make use of a Stateful widget in this case.
