Plugging into Anvil and powering up your dependency injection
summary
Explains extending Anvil with a custom code generator that reads Kotlin PSI, uses KotlinPoet to emit merge subcomponents and parent interfaces, and registers a feature injector via Dagger multibindings. Claims: migration of ~600 modules and ~500 features, sample apps auto-wire via Anvil, and a measured ~13% clean / ~15% incremental build speedup after replacing kapt/Java stubs. Shows handling factory specs (constructor args), working around Anvil’s generic multibinding limitation, and returning a scoped component holder for runtime use.
