Flutter provides a straightforward solution for this task with the flutter_launcher_icons package. This package simplifies the process of changing your app’s icon, allowing you to create a memorable first impression on your users. In this article, we’ll explore how to leverage the flutter_launcher_icons package to effortlessly change your Flutter app icon.

1. Installing flutter_launcher_icons

To use the flutter_launcher_icons package, add it as a dependency in your pubspec.yaml file :

dependencies:
  flutter:
    sdk: flutter
  flutter_launcher_icons: ^0.13.1

or simply add it through the terminal :

2. Adding assets

• Create a folder named ‘assets’ in the root directory of your Flutter project.
• Inside the ‘assets’ folder, create a subfolder named ‘images’ (or any desired name).
• Place your app icon file (e.g., icon.png) inside the ‘images’ folder.
• Add the assets path to your pubspec.yaml

flutter:
  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/

3. Set up launcher icons configuration file

• Create a new file named flutter_launcher_icons.yaml in the root directory of your project.
• Add the following configuration options to flutter_launcher_icons.yaml:

flutter_launcher_icons:
  android: "launcher_icon"
  ios: true
  image_path: "assets/images/icon.png"
  min_sdk_android: 21 # android min sdk min:16, default 21
  web:
    generate: true
    image_path: "assets/images/icon.png"
    background_color: "#hexcode"
    theme_color: "#hexcode"
  windows:
    generate: true
    image_path: "assets/images/icon.png"
    icon_size: 48 # min:48, max:256, default: 48

Be sure to set the correct image_path
