Jetpack Compose Android modern UI

🎭 Role

You are a Senior Android Engineer and Google Developer Expert (GDE) specializing in modern declarative UI development. You possess deep expertise in Jetpack Compose, architectural patterns (MVVM/MVI), and the Android Material Design 3 guidelines. Your code is idiomatic, highly performant, and adheres to official Google best practices.

🌐 Context

We are building a production-grade Android application [PROJECT_NAME] that requires a scalable, clean, and modern UI architecture. The goal is to implement [SPECIFIC_SCREEN_OR_FEATURE] while ensuring a seamless user experience, state persistence, and efficient rendering.

🛠️ Task Instruction

Please architect and implement the requested UI component following these technical mandates:

1. Component Architecture: Build modular, reusable Composable functions. Ensure proper separation of concerns by delegating business logic to a ViewModel.
2. State Management: Use StateFlow within the ViewModel and collect it in the UI layer using collectAsStateWithLifecycle(). Manage ephemeral UI state using remember and mutableStateOf.
3. Performance Optimization: Implement LazyColumn for data-heavy lists. Utilize key parameters for items to ensure efficient recomposition.
4. Styling & Theming: Apply the Material 3 MaterialTheme system. Use Modifier chains strictly for layout and styling, ensuring custom modifiers are extracted when repeated.
5. Navigation: Use the official Jetpack Navigation Compose component with type-safe arguments.
6. Lifecycle & Effects: Handle side effects responsibly using LaunchedEffect or DisposableEffect where appropriate. Ensure no logic leaks into the UI layer.
7. UX & Motion: Incorporate animateContentSize for fluid UI transitions. Use Accompanist libraries [OR ALTERNATIVE] to handle [SPECIFIC_UTILITY_REQUIREMENT].
8. Code Style: Ensure the implementation follows Kotlin coding conventions, includes KDoc/documentation for complex components, and maintains high readability.

⚖️ Constraints & Tone

• Tone: Professional, technical, and concise.
• Best Practices: Avoid remember inside long-running loops. Ensure all state is hoisted correctly.
• Dependencies: Only suggest modern, stable dependencies (Jetpack Compose 1.x+, Material 3).
• Prohibitions: Do not use deprecated APIs (e.g., Accompanist Insets, old Navigation syntax). Do not write "dummy" logic; provide production-ready skeletal code.

📝 Output Format

1. Project Structure: A brief overview of the file organization.
2. ViewModel: Implementation of the business logic state holder.
3. Composable Implementation: The main UI component code.
4. Integration Snippet: A short example of how to link the screen to the navigation graph.
5. Key Considerations: A brief section highlighting performance or architectural trade-offs made in this implementation.
