D8: Cannot fit requested classes in a single dex file

Question

I am trying to add the below dependencies:

  firebase_auth: ^0.14.0+5   google_sign_in: ^4.0.7   cloud_firestore: ^0.12.9+5   fluttertoast: ^3.1.3   image_picker: ^0.6.1+8   shared_preferences: ^0.5.3+4   firebase_storage: ^3.0.6   cached_network_image: 2.0.0-rc.1   firebase_messaging: 6.0.13   flutter_local_notifications: 1.4.0   photo_view: ^0.5.0 

I found this error:

So how can I solve this problem?

Answer 1

Add multiDex to your app-level build.gradle file. Under defaultConfig add this line

multiDexEnabled true 

Then in dependencies add multidex and check versions

implementation 'androidx.multidex:multidex: 2.0.1'
