Back in the day Java dependency injection frameworks were purely runtime based like Spring and Guava. Dagger 1 introduced a compile time component as well as compile time safety and Dagger 2 took the concept even further. Now we're going back to runtime with Dagger Reflect in an effort to improve local developer build speeds. This talk will cover the reasons for building dagger reflect, how it works under the hood, how to use it in your project as well as how it is developed.
