| Dagger `@Provides` methods may not return null unless annotated with | |
| `@Nullable`. Such a method will cause a `NullPointerException` at runtime if the | |
| `return null` path is ever taken. | |
| If you believe the `return null` path can never be taken, please throw a | |
| `RuntimeException` instead. Otherwise, please annotate the method with | |
| `@Nullable`. |
