Changing your app icon in Flutter lets you brand your app and make it stand out on users’ devices. There are two main ways to achieve this: using a dedicated package for automatic generation or manually creating icons for each platform.
1. Using a package
The most recommended approach is to use the flutter_launcher_icons package. This package simplifies the process of generating icons for different platforms (Android, iOS, etc.) from a single source image. Here’s a general guideline:
- Add the package to your pubspec.yaml file.
- Configure the package to specify the path to your icon image and which platforms you want to generate icons for.
- Run the package command to generate the icons
2. Manual approach
This approach involves manually creating icons in the required sizes and formats for each targeted platform. Here’s a breakdown for Android and iOS:
Android:
- Use an online tool like AppIcon.co to generate different sized icons for Android.
- Place the generated icons in the appropriate locations within your project’s android folder but make sure to specify its directory in the pubspec.yaml.
iOS:
- Use AppIcon.co or design tools like Xcode to create an icon set with various sizes.
- Import the icon set into your project’s ios folder using Xcode.
Additional considerations
For Android, you can use adaptive icons to create a more dynamic app icon experience.
Refer to the official documentation of flutter_launcher_icons for detailed configuration options.
Remember, whichever approach you choose, ensure your icon image has a high resolution (at least 1024×1024 pixels) for optimal quality.
