Flutter Widgets: The Building Blocks of Your App's UI

Widgets are the fundamental building blocks in Flutter, used to create the visual elements of your app. Whether you're designing a button, text, image, or a complex layout, everything in Flutter is a widget. In this guide, we’ll dive into the most commonly used Flutter widgets and how you can simplify your development using GetWidget – a popular Flutter UI library.

What is a Widget in Flutter?In Flutter, a widget describes a part of the user interface (UI). It could be a button, a text field, or even an entire screen. Widgets are classified into two main types:

• StatelessWidget: Doesn’t change its state once built. (e.g., Text, Icon, etc.)

• StatefulWidget: Can change its state over time. (e.g., Checkbox, Slider, etc.)

Top Flutter Widgets You Should Know

1. Container Widget

A Container is a box model that can be used to create a section in your UI. You can apply padding, margin, color, and size to a Container.

Example:

dart

CopyEdit

Container(

  width: 200,

  height: 200,

  color: Colors.blue,

  child: Center(

    child: Text("Hello Flutter"),

  ),

)

2. Text Widget

The Text widget is used to display text in your app. You can customize font size, color, alignment, etc.

Example:

dart

CopyEdit

Text(

  'Welcome to Flutter!',

  style: TextStyle(fontSize: 20, color: Colors.black),

)

3. Image Widget

The Image widget is used to display images in your app. You can use images from the network, assets, or file.

Example:

dart

CopyEdit

Image.network(

  'https://example.com/image.jpg',

  height: 100,

  width: 100,

)

4. Row and Column Widgets

• Row Widget: Aligns children horizontally.

• Column Widget: Aligns children vertically.

Example:

dart

CopyEdit

Row(

  mainAxisAlignment: MainAxisAlignment.center,

  children: [

    Text('Item 1'),

    SizedBox(width: 10),

    Text('Item 2'),

  ],

)

5. Button Widget

The ElevatedButton is one of the most commonly used buttons in Flutter. It allows you to perform an action when clicked.

dart

CopyEdit

ElevatedButton(

  onPressed: () {

    print('Button Clicked');

  },

  child: Text('Click Me'),

)
