Multidex issue with Flutter

Question

I\'m getting the following error compiling with gradle using Flutter in Android Studio:

Dex: Error converting bytecode to dex:
Cause: com.android.dex.DexExce         


        

Answer 1

Your two packages seem to disagree on their transitive dependencies. One wants 11.6.+, the other wants 11.+ of some play-services dependencies. Since both 11.6.2 and 11.8.0 are out there, this is going to end up with a conflict.

If you run ./gradlew androidDependencies in your android/ folder, you get a listing of the result of dependency resolution, containing, among others, the following:

+--- :flutter_google_place_picker (variant: release)
+--- com.google.android.gms:play-services-location:11.8.0@aar
+--- com.google.android.gms:play-services-places:11.6.2@aar
+--- com.google.android.gms:play-services-maps:11.6.2@aar
+--- com.google.android.gms:play-services-base:11.8.0@aar
+--- com.google.android.gms:play-services-tasks:11.8.0@aar
+--- com.google.android.gms:play-services-basement:11.8.0@aar

These 11.6.2 and 11.8.0 packages are not going to work together. To resolve this, you need to patch your dependencies to be consistent with each other, or add a dependency override to the top level of your android/app/build.gradle file and hope for the best:

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-places:11.8.0'
        force 'com.google.android.gms:play-services-location:11.8.0'
    }
}
