We'll cover basic navigation in Jetpack Compose without third-party libraries. We'll create a screen state, enable screen switching using the "when" method, work with callbacks, and see how a manual approach works. I'll explain why currentScreen = "next" is convenient for getting started, but unsuitable for production.
If you're developing an Android app with Compose, you need to understand not only how to use Navigation Compose but also how navigation works under the hood.
