how to share location for real time tracking in flutterflow

I am going to make an app, it is a bus tracking app, in which first choose account type, driver and user options will be there, and after the driver clicks on it, the GBS location permission will be asked and then his current location will be shared with the user. After clicking the start travel button on the driver app, create an app so that the user knows the location of the bus driver with the GBS facility of the driver's mobile and do it through flutter flow... Please Explain Me
