Flutter building apk: Duplicate class found in modules guava-26.0-android.jar and listenablefuture-1.0.jar

I am getting a strange bug trying to build apk on Flutter:

% flutter build apk --no-shrink
You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

Any ideas?

Solution taken from this stackoverflow post.

Google knows about this error so they made a special package to fix the conflict.

Add this to your build.gradle

implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
