Questions tagged [dagger-hilt]

Hilt is a Dagger2-based dependency injection library for Android.

The goals of Hilt are:

  • To simplify Dagger-related infrastructure for Android apps.
  • To create a standard set of components and scopes to ease setup, readability/understanding, and code sharing between apps.
  • To provide an easy way to provision different bindings to various build types (e.g. testing, debug, or release).
