ESSENTIAL JETPACK COMPOSE
CHEAT SHEET
Compose fundamentals at a glance | State, recomposition & side effects | Layouts & Material | PDF
Need a no-fluff reference for Compose?
This cheat sheet will give you a practical reference for Compose essentials—what triggers recomposition, how to manage state, when to use side effects, and the key building blocks.
Yes, I need it!
Here's what you'll find inside:
Composable functions anatomy — how to design reusable components (parameters, Modifier, slot APIs).
State & recomposition (no magic) — what actually triggers recomposition and how to keep it under control.
Stable vs unstable state — simple rules for when Compose can optimize, and when it has to do extra work.
State hoisting in practice — local vs parent vs ViewModel state + when to use remember, rememberSaveable, and retained state.
Delayed state reads — avoid “recompose on every pixel” patterns (the lambda-based approach).
Side effects — LaunchedEffect, DisposableEffect, SideEffect: when to use each and what to avoid.
Core building blocks — essential layouts and Material components (Column/Row/Box/Scaffold, Lazy*, and more).
Here's what you'll find inside:
Components & UI building blocks
Composable functions anatomy — reusable components (parameters, Modifier, slot APIs).
Core building blocks — essential layouts & Material (Column/Row/Box/Scaffold, lazy lists & grids).
State & recomposition
State & recomposition (no magic) — what triggers recomposition and how to control it.
Stable vs unstable state — simple rules for when Compose can optimize vs when it can’t.
State hoisting in practice — local vs parent vs ViewModel + remember / rememberSaveable / retained state.
Effects & performance patterns
Delayed state reads — avoid “recompose on every pixel” patterns (lambda-based approach).
Side effects — LaunchedEffect, DisposableEffect, SideEffect: when to use each and what to avoid
