Stateless vs Stateful widget lifecycle in Flutter

Difference

This blog will learn about stateless and stateful widgets’ lifecycle. We shall learn about all the methods that are used to maintain the lifecycle of the stateful widgets. So let’s get started.

Stateless Widget:

2. These widgets are immutable once they are built.
3. Any change in data, widgets, icons, or variables do not change the state of the app or UI.

The Lifecycle of stateful widget:

1. createState(): When we create a stateful widget, a…
