Mobile video app built with Flutter
The Flutter SDK for Video & Audio provides pre-built widgets so developers can move quickly to integrate real-time video capabilities in their applications. Using our SDK, developers can opt to use our customizable out-of-the-box solution or write their own UIs using our low-level SDK – all while avoiding the hard parts of multi-platform development.
