Flutter Icon Widget Tutorials

we will learn about the Flutter icon widget, how to use it, how to modify some of its features, etc.

Icons can be used as a symbol of representation to help users quickly comprehend a function or the navigational path, for example.

The list of cases we’ll talk about is below.

  1. Basic Icon widget example, with default values.
  2. Change Icon Size using size property.
  3. Change Icon Color using color property.
  4. Icon with a Text Label below it with the help of Column widget.

This example demonstrates a Flutter Icon with just the icon specified and other properties left to default values.

You can specify the required icon as argument to Icon class. The list of all icons that come with flutter are available in Icons class. You can also use icons from assets.

Create a StatefulWidget named “IconWidgetExample” that will hold the main logic for your example:

class IconWidgetExample extends StatefulWidget {
  @override
  _IconWidgetExampleState createState() => _IconWidgetExampleState();
}

class _IconWidgetExampleState extends State<IconWidgetExample> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Icon Widget Tutorial'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Icon(
              Icons.favorite, // Replace with the desired icon
              size: 80.0,
              color: Colors.red,
            ),
            SizedBox(height: 16.0),
            Text(
              'This is a heart icon!',
              style: TextStyle(fontSize: 20.0),
            ),
          ],
        ),
      ),
    );
  }
}

Now, you need to implement the example in the main.dart file:

import 'package:flutter/material.dart';
import 'icon_widget_example.dart'; // Import the Dart file you created earlier

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Icon Widget Tutorial',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: IconWidgetExample(), // Use your IconWidgetExample widget as the home
    );
  }
}

With the example in place, you can now write your blog post to explain the usage of the Icon widget. Make sure to include the following points in your tutorial:

  • Introduction to the Icon widget and its significance in Flutter apps.
  • How to import the necessary packages and set up a Flutter project.
  • Explanation of the code, highlighting the Icon widget’s properties like “Icons“, “size“, and “color“.
  • Displaying the heart-shaped icon using the Icon widget.
  • A brief explanation of the Scaffold, AppBar, Center, Column, and Text widgets used in the example.
  • Conclusion and possible use cases of the Icon widget in real-world apps.
