+# Flutter Agora Fully Functional Video Call module
+
+## Tech Stack
+
+**Client:** Dart, Flutter
+
+**Server:** Firebase firestore, Google cloud functions
+
+## Techniques:
+
+*BloC pattern with Cubit State management
+
+*Fully Real-time data-consuming for (Users-History-VideoCall status)
+
+*Real-time handling for all call status (calling - accept- reject - cancel - busy - unAnswer - end)
+
+*Clean code and arch
+
+*Ui=>Cubit=>Api data flow
+
+*Dio package for deals with (generate agora token - FCM) api
+
+*Fcm notification (handling incoming calls in terminated mode)
+
+**Build token generator using nodejs:** https://www.youtube.com/watch?v=KcLypppA2IQ&ab_channel=Agora
+
+**Demo Video :** https://www.youtube.com/watch?v=Ond-VhB11h4

+
+
+## Getting Started
+
+*Create a new firebase project and setup firestore and enable email/password authentication
+
+*Copy FCM authorization key and past it on fcmKey var in constants.dart file
+
+*Create agora new project and general token, channel name for test purpose and past them with your appId on (agoraAppId-agoraTestChannelName-agoraTestToken) vars in constants.dart file

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
