I am making a project on fingerprint indoor Navigation through flutter.I have made an app that stores each major locations University stationary wifi rssi value and it's respective bssid , gsm rssi value and gps location values. But I have no idea about any of the algorithm which filters the fingerprints and which helps in navigation on the map through the fingerprint. Is there any specific algorithm or flutter package I can use for this project. In advance thanks for the help.
