Unused Modules and Component Dependencies

When the Dagger processor generates components, it only requires instances of modules and component dependencies that are explicitly needed to supply requests for a binding.

• If all of a module’s methods that are used in the component are static, Dagger does not need an instance of that module at all. Dagger can invoke the static methods directly without a module.
• If a module provides no bindings for a Component, no instance of that module is necessary to construct the graph.
