Saffar App
What is Saffar?
A Test Taxi booking application.
Saffar is an open source project to showcase the use of Flutter with a Node JS backend (Saffar backend repository link here) along with TomTom maps service (Google Maps alternative. Link here).
The app uses Flutter as it’s frontend framework, TomTom as it’s map service, Hive as it’s local storage and Razorpay as it’s payment gateway. Clean architecture (Clean architecture lectures link here) is used to keep the app modular and it’s UI logic, Business logic and Data logic separate. It uses Bloc and Cubits state management which handles state in a clean and optimal manner.

TomTom maps service
TomTom maps service is a good alternative for Google Maps for testing your apps with maps, also it has a free tier. It contains all the major services that are needed for most of the apps. It doesn’t have a dedicated SDK for flutter as of now i.e. when this README.md file is being written. (If in future a TomTom SDK for flutter is available please raise an issue to correct this README.md file). So, for now we have to work with APIs provided bt TomTom and using flutter_map. I will be writing a tutorial on how to use TomTom map service in Flutter, so stay tuned.
