Hi!

DeepAR [Flutter plugin](https://github.com/ridvanaltun/react-native-deepar) is an open-source project developed and maintained by the DeepAR community. DeepAR does not actively maintain nor provide customer support for them. Our support covers only native mobile (iOS and Android), Web, and MacOS, and future development will focus on those platforms.
