SPIDER LATERAL INDUCTIONS Task Submission Problem statement : Scaling a Real-time chat app

 Front-end Development :

 Design: Created screen designs using Figma, a cloud-based design tool, to visualize the user interface.

 Development: Utilized Flutter, an open-source framework for cross-platform development, for designing, text editing, navigation, and integrating with the backend. I have implemented several pages like

• Home Page • Sign Up • Login • Forget Password • Chat List Page • Chat Window Screen • Chat Room Page • Settings Page  Profile Page  Security Page  Add Chat Room Page  Notification Page  Help Page  Add Contact Page  Invite Page

 Back-end Development:

 API Development: Developed APIs using C# within the Visual Studio environment to handle various functionalities. I have used API for • Sign Up • Login • Forget Password • Add contact • Getting chat list • Saving User profile • Add ChatRoom • Implementing Websocket

 Database Creation: Established tables using SQL Server to manage and store all the required databases effectively. Several tables are created – • User Table • Contact Table • Chat Room Table

 API Implementation: Implemented APIs using Swagger, ensuring a standardized and documented approach for API development. Lot of Get and Post method are created and displayed.  API Hosting: Hosted the APIs using Internet Information Service Management, ensuring accessibility and availability.

 API Testing: Conducted API testing using Postman to validate functionality, identify bugs, and ensure reliability.  API Integration: Integrated the APIs into the Flutter application for security, error handling, data retrieval, and presentation purposes, creating a seamless interaction between the front-end and back-end systems. • WebSockets Integration: Implemented WebSockets to establish a two-way communication channel between the server and the Flutter application, enabling real-time data exchange. This facilitates instant messaging and updates within the application, enhancing user engagement. Used C# for websocket and integrated with flutter.
