sharedPref.CurrentChargePoint = CurrentChargePoint
if (sharedPref.token.length > 0) {
Log.d("@@@@@@@", "${sharedPref.token}: ")
sharedPref.isAdhocBooking = false
findNavController().navigate(R.id.navigation_reserve) // in this line
} else {
findNavController().navigate(R.id.navigation_settings_login)
}
}
R.id.mapView -> {
StationInfo.isVisible = false
}
R.id.qrButton -> {
findNavController().navigate(R.id.activity_qr)
