Fix Flutter Launcher Icons Package Error

This article describes how to resolve the flutter_launcher_icons package error that may occur during app build or deployment.

Prerequisites

Access to your FlutterFlow project.
Ability to open and edit the pubspec.yaml file.
Familiarity with your build environment (FlutterFlow, GitHub, or IDE).

Understanding the Error:

During the build process, you might see the following error message:

Codemagic Deploy Output Failed Step: Generate Launch Icon Could not find package "flutter_launcher_icons". Did you forget to add a dependency? pub finished with exit code 65. Build failed: Step 5 script 'Generate Launch Icon' exited with status code 65.

This error indicates that the flutter_launcher_icons package is missing or not configured correctly.

Follow the steps below to fix the error:

Clear and Reset App Assets in FlutterFlow:
- Navigate to Settings and Integrations > App Assets inside FlutterFlow.
- If the Splash Screen and Launcher Icon are set:
  - Clear both assets.
  - Re-upload the launcher icons.
Add flutter_launcher_icons Package in GitHub Deployment If you are deploying via GitHub and encounter this error, add the package to your pubspec.yaml file:
- Open your pubspec.yaml file.
- Add the following under dev_dependencies:
```
dev_dependencies:
flutter_launcher_icons: "^0.10.0"

flutter_icons:
android: true
ios: true
image_path_ios: "assets/images/launcher/ios.png"
image_path_android: "assets/images/launcher/android.png"
```
  - *flutter_launcher_icons: "^0.10.0" specifies the package version.
  - image_path_ios and image_path_android specify the paths to your launcher icon images.
  - Ensure the image files exist at the specified paths.
Run the following commands in your terminal or IDE:
```
flutter pub get
```
```
flutter pub run flutter_launcher_icons:main
```
```
flutter run
```
flutter pub get fetches packages.

flutter pub run flutter_launcher_icons:main generates launcher icons.

flutter run builds and runs the app.
