Flutter and React Native Expert

We are looking for experienced developers in Flutter and React native specifically to assist us with our app project. Templates are welcome and we can buy one. We are looking for a directory that you can find establishments. The map should be able to show you points of interest as you travel to an area. Once you come close to one it sends a push notification to remind you. The rest is standard directory features. There is a payment gateway to allow establishments to list themselves.
