ToDo App

This ToDo App is a powerful and efficient task management tool designed for Android, built using Jetpack Compose, Kotlin, and modern Android development practices such as Dagger-Hilt for Dependency Injection, Room Database for local storage, and Material Design Components for an intuitive user experience. The app features CRUD operations (Create, Read, Update, Delete) for tasks, utilizes ViewModel and LiveData for reactive UI updates, and offers a beautiful StaggeredGridLayout for displaying tasks.

Features

• Task Management (CRUD):

  • Users can add, edit, delete, and view tasks.
  • Tasks are stored locally using Room Database.

• Deadline Management:

  • Set deadlines using MaterialDatePicker and MaterialTimePicker.
  • Remaining time for tasks is calculated and displayed.

• Modern UI/UX:

  • RecyclerView with StaggeredGridLayout for task display.
  • Material Design principles for a clean and user-friendly interface.

• Dependency Injection with Dagger-Hilt:

  • Dagger-Hilt is used for seamless Dependency Injection throughout the app, improving testability and modularity.

Architecture

The app follows the MVVM (Model-View-ViewModel) architecture pattern to ensure separation of concerns and facilitate easier testing and maintenance.

Layers:

1. UI Layer (View):

   • Jetpack Compose-based UI components.
   • Fragments and Navigation Components for routing between screens.

2. ViewModel Layer:

   • TaskViewModel interacts with the repository and handles UI-related data, making use of Kotlin coroutines and viewModelScope to manage background tasks efficiently.

3. Repository Layer:

   • TaskRepository handles data operations by interacting with the local data source (Room) via a DataSource class, abstracting data access logic from the ViewModel.

4. Room Database Layer:

   • Local storage of tasks using Room with an Entity-DAO pattern.

Tech Stack

• Kotlin: Programming language.
• Jetpack Compose: For building the UI in a declarative manner.
• Room: For local database management.
• Dagger-Hilt: For Dependency Injection.
• Coroutines: For asynchronous operations.
• LiveData: For observing and updating the UI.
• RecyclerView: For displaying tasks.
• MaterialDatePicker and MaterialTimePicker: For selecting task deadlines.
• Navigation Component: For handling in-app navigation.
