Best Practices for Composition Patterns in Jetpack Compose

Jetpack Compose, a declarative UI framework, lacks specific design patterns for UI component composition compared to the well-established React ecosystem. The article explores adapting React's UI design patterns, particularly the Slot and Compound Component patterns, to enhance the reusability and flexibility of Jetpack Compose components. The Slot pattern allows for flexible UI customization by using composable lambdas as parameters, while the Compound Component pattern, inspired by React, separates child components from state management, focusing on UI rendering. These patterns address issues like the "if-else hell" caused by excessive conditional statements, which complicate component maintenance and violate the Single Responsibility Principle. Examples such as SNS profile cards, Stream Video SDK, and design systems illustrate practical applications of these patterns. The article emphasizes understanding when to apply these patterns versus simpler solutions like conditional statements or intentional duplication, stressing the importance of balancing simplicity and complexity based on the specific UI requirements and expected changes.
