Migration to Metro

The dependency injection library is now Metro. It replaces both Dagger and Anvil.

Migration of the current Element X code has been performed in https://github.com/element-hq/element-x-android/pull/5253.

To migrate other existing code you will need to:

  • replace setupAnvil() with setupDependencyInjection() in your build.gradle.kts files
  • replace the Dagger and Anvil imports with Metro ones
  • move the @Inject apply to the constructor to the class itself (only applicable if there is only one primary constructor
  • replace @AssistedInject with @Inject
  • replace @Module with @BindingContainer

This should help to migrate your existing code.
