Why Flutter?

With apps for iOS, Android, web, and macOS, cross-platform support was an absolute necessity. After considering other frameworks, the team at ROMWE discovered Flutter in July 2019, and was immediately interested in its multi platform coding ability. After reading the documentation on, the team built a proof of concept to evaluate the platform. The proof of concept was meant to test a variety of factors, including development efficiency, performance, UI performance, and code push. The most important factors, though, were performance and development efficiency, for which Flutter quickly impressed, along with its flexibility and ease of use. After that, Flutter became the easy choice.

Their solution
