D8: Cannot fit requested classes in a single dex file

Issue

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:

D8: Cannot fit requested classes in a single dex file (# methods: 85948 > 65536)
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

  # The following adds the Cupertino Icons font to your application.

    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/
    - assets/design_course/
    - assets/fitness_app/
    - assets/hotel/

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: WorkSans
      fonts:
        - asset: assets/fonts/WorkSans-Regular.ttf
        - asset: assets/fonts/WorkSans-Medium.ttf
          weight: 500
        - asset: assets/fonts/WorkSans-SemiBold.ttf
          weight: 600
        - asset: assets/fonts/WorkSans-Bold.ttf
          weight: 700
    - family: Roboto
      fonts:
        - asset: assets/fonts/Roboto-Bold.ttf
        - asset: assets/fonts/Roboto-Regular.ttf
        - asset: assets/fonts/Roboto-Medium.ttf
          weight: 400
  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

So how can I solve this problem?

Solution

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'
