I moved to Flutter since its inception because of its single code base approach, Reliability and smoothness which is better then any available Cross-Platform or Single Codebase language. As Flutter developer I’m experienced with: Dart lang, RxDart, Web services, socket, Rest full API, HTTP in Flutter, all Firebase Framework, effectively scale UI according to different screen sizes, localization of the app, GoogleMaps and working with location, SharedPreferences, SQLite, integration with server in NodeJS, mongoDB.
