When you encounter a build failure related to Kotlin compilation in a Flutter project, it usually indicates a problem with the Kotlin code in one of your dependencies or plugins.Here’s a step-by-step approach to resolve this issue:
Check the Logs
Run the build command with additional options to get more details in the terminal of Vscode or Android Studio:
flutter build apk –verbose
Or, if you’re using Gradle directly:
./gradlew assembleDebug --info
Update Kotlin and Gradle Versions
Look for specific error messages or issues in the logs. This might give you hints about what’s going wrong.
Kotlin Version
Open your android/build.gradle file and update the Kotlin version: [https://kotlinlang.org/docs/releases.html#release-details] this link shows kotlin latest version use that one based on flutter version here i m using 2.0.20
ext.kotlin_version = '2.0.20' // Use the latest compatible version
Gradle Wrapper:
Open android/gradle/wrapper/gradle-wrapper.properties and update the Gradle distribution UR
distributionUrl=https\://services.gradle.org/distributions/gradle-8.0.2-all.zip
Gradle Plugin:
Go to android/build.gradle and update the Gradle plugin version:
classpath 'com.android.tools.build:gradle:8.0.2'
Clean and Rebuild
After update then run following commands one by one in terminal
flutter clean
flutter pub get
flutter build apk
Check for Plugin Updates
flutter pub upgrade
Verify Compatibility
Ensure that all your plugins and dependencies are compatible with your Flutter and Kotlin versions. Incompatibilities can cause unexpected build issues.
If any package create issue in pubspec yaml file remove version so that it will work like this:
#old
http: 2.00
#new
http: #2.00Review Kotlin Code
If the issue seems related to a particular plugin (e.g., flutter_shieldfraud), check if there’s a known problem or recent bug report with that plugin. You can:
- Look at the Plugin’s Issue Tracker: Search for similar issues.
- Contact Plugin Maintainers: If there’s no solution, consider opening a new issue or reaching out to the maintainers.
Stop the Gradle Daemon
Sometimes, issues arise from the Gradle Daemon process. Try stopping it and then rebuilding:
./gradlew --stop
flutter build apk
Use the --stacktrace Option
If you still need more detailed information, use the stack trace option:
./gradlew assembleDebug --stacktrace
After following these steps, the flutter_shieldfraud:compileDebugKotlin issue should be resolved. If you still face any problems, feel free to reach out to us or share the issue in the comments, and we’ll suggest alternative solutions.
