Watch App

This document outlines the specifications and requirements for the Flutter application task during the internship process. The project involves creating a functional app with registration, login, and movie list features, using the Parse Platform API for backend and local database integration.

---

Task Overview

The application consists of two main screens:

1. Login Screen:

   • Includes input fields for username and password.
   • Buttons to either register a new user or log in with existing credentials.

2. Dashboard Screen:

   • Displays a scrollable list of movies retrieved from a remote database.
   • Shows details for each movie, such as the title, description, and additional movie information.

Requirements

1. Login Functionality

• Allow user registration with a unique username and password.
• Enable users to log in using their registered credentials.

2. Remote Database Integration

• Use the Parse Platform API for backend services.
• Store and retrieve movie list data locally using a caching mechanism.

---

Implementation

1. Technology Stack

• Frontend: Flutter for cross-platform development.
• Backend: Parse Platform API for data fetching and local storage management.

2. User Interface

• Design the UI as per the provided wireframes.
• Ensure the app is responsive across various screen sizes.

3. Code Quality

• Write clean and modular code.
• Add comments to explain the purpose of functions and components.

Features

Main Functionality

1. Movies List:
   • Fetch and display movies with pagination.
2. Details Navigation:
   • View detailed information about a movie.
3. Pagination:
   • Navigate through pages of movies using arrow buttons.

Architecture Overview

1. Login to MainView Navigation

• Upon successful login, the app navigates to MainView using a custom router.

2. Dependency Injection Setup

• Use initHomeModule() to set up necessary dependencies, such as HomeUseCase and MainViewModel.

3. State Management with Provider

• Use ChangeNotifierProvider to manage state updates and notify UI components reactively.

4. Data Fetching Flow

1. Start Method:
   • Initiates data loading in MainViewModel.
2. Repository Pattern:
   • Fetch data from the local database first. If unavailable, retrieve it from the remote API via AppServiceClient.

5. Error Handling

• Handle API response errors gracefully using the Either type.
