guys, code style question about nullable context.. (After api 27 android added `@Nullable` to `public Context getContext()`)
I have method `getUserComponent(context: Context): UserComponent`, which is used inside `onCreate` across whole app.
1. First solution is to add `!!` everywhere 
```App.getUserComponent(context!!)```
But i can't look at all this `!!` without disgust feeling
2. Second is to make context param of getUserComponent nullable and fire exception in case of null
```fun getUserComponent(context: Context?) = context!!.getApp().legacyAppComponent```
Is that ok to allow method to take nullable param, but throw exception in this case?
