Sharp-eyed readers of this series may have noticed something…suboptimal: Up until this point, we’ve been creating certain objects as global variables. They’re immutable, so that may be technically OK, but those of a certain age have been taught for years how wrong that is, so technically OK or not, it just feels gross. In this post, we’re going to fix that with by implementing inversion of control with Koin...

In the last entry, we looked at how to read data from the device’s local database using Room and display it on the screen, but we did so using dummy data. In this entry, we’ll look at how to use Room in our components to persist user-entered data in our SQLite database...

In the last post, we added the various pieces to make navigation possible and stopped JUST short of the goal line. In this post, we’ll finish up our navigation discussion by adding a new screen and seeing navigation in action...

So far, we have an app that runs but has only one "screen". Decompose makes adding more screens — and navigating between them — pretty simple. In this post, we’ll start to see how that’s done...
