Widget Lifecycle :

Everything in Flutter is a Widget, so before knowing about Lifecycle, we should know about Widgets in Flutter.

There are two types of widgets in Flutter.

• Stateless Widgets.
• Stateful Widgets.

Before knowing about the Lifecycle, we need to understand the difference between the two widgets.

=> Stateless Widgets: Stateless Widgets in Flutter are those widgets whose state once created cannot be changed, it becomes immutable like on variables, buttons, icons, etc., or any state that cannot be changed on the app to retrieve data. Returns a widget by overwriting the build method. We use it when the UI relies on the information inside the object itself.
