Exploring Flutter Widgets

The building blocks of the user interface (UI) in Flutter are known as Widgets. Everything you create in a Flutter app, from the simplest button to complex layouts, is in a widget. In short, these widgets in Flutter represent an app’s visual and interactive elements. Widgets (the heart and soul of Flutter) can be categorized into five divisions.

Categories	Different Widgets in Each Category
Structural Widgets	Center, Container, Column, Row, Stack
Functional Widgets	GestureDetector, Form, Expanded, ListView, Navigator
Styling Widgets	Padding, Align, DecorateBox, Transform, Opacity
Composition Widgets	Column, Row, Stack, GridView, Wrap
Text and Icon Widgets	Text, RichText, Icon, Image, FlutterLogo

Two Types of Flutter Widgets (On the Basis of Change of State): Stateless vs Stateful Widgets

Flutter Widgets can also be classified into two primary types – Stateless and Stateful, on the basis of their change of state. Let’s differentiate both of them to understand their crucial meaning.

1. Stateless Widgets:

Meaning:

Stateless widgets are immutable, meaning that once they are built, they cannot change their state or properties. They are particularly designed for situations where the UI doesn’t need to update or change based on user interaction or other events.

Key Characteristics:

The properties of a Stateless widget are final and cannot be altered once the widget is created.
They have a single build() method.
Since stateless widgets are immutable, they don’t need any updates or an internal management system.

Example:

Container, Padding, Center, DecoratedBox, Opacity & More.

2. Stateful Widgets

Meaning:

As the name ‘Stateful’ itself suggests, Stateful Widgets are dynamic and can change over time in response to user action or other events. Unlike ‘Stateless Widgets,’ they maintain a mutable state that can be updated, causing the widget to rebuild and reflect the changes.

Key Characteristics

They are mutable, dynamic, and ever-evolving.
The State object can be updated, and when it is, the widget’s build() method is called again to reflect the updated state.
They have a plethora of lifecycle methods that allow developers to handle initialization and resources and perform cleanup.

Examples:

Checkbox, Slider, Textfield & Animated0pacity.

Summing Up: Stateless vs. Stateful Widgets

Aspect	Stateless Widget	Stateful Widget
Mutability	Immutable	Mutable
State Management	No internal state management	Manages state via State object
Lifecycle Methods	Only build() method	Full lifecycle methods
Use Cases	Static content, simple layouts	Interactive, dynamic UIs
Performance	Typically faster due to immutability	Slightly slower due to state management
