Graduation
Look how far you've come
Twelve modules ago, val versus var was news. Now look at what you can read — and write:
- Kotlin itself — constants, nullability, data classes, lambdas,
when, sealed interfaces (Modules 1–3) - Serializable models & coroutines — the entire assistant section of
Models.kt, snake_case JSON and all, plussuspend fun(Module 3) - Jetpack Compose — composables, layout, modifiers,
remember,StateFlowview models (Modules 4–6) - A design system — the
Hudtokens and typography on every screen (Module 7) - Networking & auth — Retrofit,
Network.kt, the DataStore token, the auth interceptor (Modules 8–9) - Real screens — lists, navigation, booking flows, a live map (Modules 10–12)
- And today — an AI assistant that was, honestly, just all of the above again
That last point is the real graduation gift: the 'hardest' feature in the app introduced zero new concepts. That's what knowing a stack feels like — new features stop being new, and start being combinations.
