JustResponsiveUi

JustResponsiveUi is a minimal Android app that demonstrates building adaptive Jetpack Compose UIs for phones and tablets (portrait and landscape). It includes separate Login and Register flows with shared domain validation, MVVM ViewModel + StateFlow, and Dagger Hilt dependency injection.

Overview

• Small, focused codebase that illustrates adaptive Compose layouts, MVVM separation, and single-source validation logic for authentication.

Architecture

• Pattern: MVVM — ViewModel holds UI state and exposes StateFlow; composables render state and emit events.
• Layers: domain (use-cases), presentation (Compose screens + ViewModels), DI modules.

Tech Stack

• Kotlin
• Jetpack Compose (Material3)
• Dagger Hilt (DI)
• Navigation3 (compose-compatible)
• Kotlin Coroutines, StateFlow
• Gradle (wrapper)
