Create a Chat Room App with Twilio Video and Flutter / BLoC

Create a Chat Room App with Twilio Video and Flutter / BLoC. In this tutorial, you'll create a Flutter app that uses an unofficial Flutter package for interfacing with Twilio Video, allowing users to host a call and be joined by multiple other users. The app will use the Business Logic Components pattern (BLoC) to separate business logic from the presentation layer, enabling code reuse and efficiency. The app will set up a serverless endpoint to generate access tokens for users to connect to the same chat room, represented as a grid of video streams. The tutorial assumes basic knowledge of Dart and BLoC, and provides step-by-step instructions on setting up the local dev environment, creating the backend service, writing the Cubit object, and connecting to Twilio Video.
