State Management and Software Architecture Approaches in Cross-platform Flutter Applications

: Flutter is an open-source cross-platform development framework. It is used to develop applications for Android, iOS, Windows, Mac, Linux, and web. This technology was released on December 4, 2018, and it is quite young technology with a lack of good architectural patterns and concepts. In this paper authors compared state management approaches used for Flutter applications development and architecture. They also proposed a combination of two approaches that solve the main problem of existing approaches related to global and local state management. The proposed solution can be used for development even complex and big Flutter applications.
