Q&A Hub - Flutter & Firebase

Download APK

Q&A Hub is a community-driven app where users can post interview questions, explore existing questions, save their favorites, report irrelevant or poorly constructed questions, and share questions as text. The app is built using Flutter for cross-platform mobile development and integrates with Firebase for backend services such as Authentication, Firestore (NoSQL database), and Firebase Storage.

This app allows users to interact with the content, while also providing an admin panel to manage reported questions and ensure quality content. Users can filter and search questions by topics, and admins can approve/reject posts based on relevance.
