Icon Explained | Flutter for Android Developers

What’s Icon?

The Icon class is a graphical widget in Flutter that displays an icon drawn from a font, specifically using an IconData object. It is commonly used to represent actions or features visually in an application. Important properties include ‘color’, ‘size’, and ‘semanticLabel’.

Icon explained for Android Developers

For Android developers, the Icon class in Flutter is similar to using ImageView with drawable resources in Android. Instead of using XML to define icons, Flutter allows you to use predefined icons from the Icons class, making it easier to implement and customize icons directly in your code. Unlike Android’s ImageView, the Icon widget is not interactive; for interactive icons, Flutter provides the IconButton class.

Example Code

Here is an example of how to use Icon:

const Row(
  mainAxisAlignment: MainAxisAlignment.spaceAround,
  children: [
    Icon(
      Icons.favorite,
      color: Colors.pink,
      size: 24.0,
      semanticLabel: 'Text to announce in accessibility modes',
    ),
    Icon(
      Icons.audiotrack,
      color: Colors.green,
      size: 30.0,
    ),
    Icon(
      Icons.beach_access,
      color: Colors.blue,
      size: 36.0,
    ),
  ],
)

Icon Remarks

In conclusion, the Icon class in Flutter provides a simple and effective way to incorporate icons into your applications. By understanding its properties and how it compares to Android’s icon handling, developers can create visually appealing and accessible interfaces.
