This project is a product development using Flutter. The Parking Management system will not be as simple as you might buy on Codecanyon and other places.
In a short description, below are the high-level scope of product features:
1. Standard Parking Management includes entry and exit of a vehicle, billing based on billing master, etc.
2. Multiple parking locations with their individual billing rates and capabilities.
3. Integration with various payment gateways.
4. Automatic Number Plate/License Plate reading (ANPR/LPR).
5. Develop Integration with Cash Dispensing devices.
6. Develop Integration with Credit/Debit Card Swipe machines.
7. Take input data, read from the Parked vehicle, and show the occupancy.
Backend Development, Frontend Development, and Flutter-based Android and iOS app development, all are part of this work.
If you are advanced and expert enough then only bid on this project. You can work as an individual or as a team, but you have to be professional enough to work on this project.
