    // Compose
    implementation(platform(libs.androidx.compose.bom))
    implementation(libs.androidx.ui)
    implementation(libs.androidx.ui.graphics)
    implementation(libs.androidx.ui.tooling.preview)

Architecture

The app follows MVVM (Model-View-ViewModel) architecture with a clean separation of concerns:

Data Layer

• Room Database: Stores task data locally
• Repository Pattern: Abstracts data operations from the rest of the app

Domain Layer

• Models: Data classes representing app entities
• Use Cases: Business logic for task operations

Presentation Layer

• ViewModels: Manages UI state and business logic
• Composables: Declarative UI components
• State Management: Unidirectional data flow with StateFlow

Dependency Injection

• Koin for dependency injection, making components testable and decoupled
