Optimize Jetpack Compose: Performance & Best Practices
Jetpack Compose offers a declarative approach to building UIs in Android. However, like any UI framework, optimization is key to achieving smooth performance and a great user experience. This detailed guide expands on the provided checklist, offering in-depth explanations and practical code examples for each optimization technique. I. Core Principles: Laying the Foundation for Performance Use Stable Types: Compose relies on stable types to efficiently track changes and minimize recompositions. A stable type guarantees that if two instances of the type are equal according to equals() , they will always be equal. Using unstable types can force unnecessary recompositions. // Stable data class (recommended) data class User ( val name: String, val age: Int ) // Unstable list (avoid directly in Compose state) // Use SnapshotStateList instead val users = remember { mutableStateListOf<User>() } // Cor...
