Say you have a package my_stuff. It contains two classes, A and B. You want to store them in separate files, but A needs access to some private functionality of B (in this case, the method _secret() and the constructor B._magic()). You don't want to expose that functionality outside of the package. You can express that like this:

The app using your package does:

some_app.dart:

sienatime

@Database(entities = {
    Entry.class, Sense.class, CrossReference.class, EntryFts.class
}, version = 4, exportSchema = false) public abstract class AppDatabase extends RoomDatabase

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle
