Мастер-класс

Embracing Jetpack Compose

Jetpack Compose is the new native, Kotlin-only UI toolkit on Android. Like React, Flutter, and SwiftUI, it’s declarative, thus overcoming the issues and weaknesses of traditional imperative frameworks. This workshop introduces various aspects of Jetpack Compose, for example composition and recomposition, state hoisting and unidirectional data flow. We will also be looking at Material You, the latest version of Googles design language, and how it is applied to a Compose app. The workshop will include many programming examples in Kotlin.

Содержание
  • Part 1: Understanding the declarative approach
    • From Android Views to composable functions (imperative vs. declarative ui frameworks)
    • How Compose UIs are made (Composable functions, composition, unidirectional data flow)
    • Wait, no component hierarchies? (Composition over inheritance)
  • Part 2: Advanced Compose
    • Animating your Compose UI
    • Best of both worlds – Compose-View-interop
    • Testing and debugging Compose apps
  • Part 3: Above and beyond
    • What Compose currently can’t do
    • Compose on other platforms
    • Friends – a brief comparison with other declarative ui frameworks
