Kotlin Academy

Today I want to write on nullability checks that Kotlin does “under the hood”, why sometimes our beloved language deserves a little bit of attention to avoid mistakes and how big-K translates our pretty code in JVM bytecode. In particular, we have to give extreme attention when we are forcing non-null objects on Kotlin, because everything could — really! — end in a NPE (aka Null Pointer Exception, aka “dead”).

Dependency Injection is a pattern, not any particular framework. You could even implement it manually, but that would be too much trouble . Wait.. Why? How do we know that?

Today we are going to explain how to use the fabulous Dagger 2 multibindings with new Architecture Components ’ ViewModel class.
