我写了这个可组合的函数来跟踪用户的位置。

@SuppressLint("MissingPermission")
@Composable
fun GpsTracking() {
    val ctx = LocalContext.current
    val locationManager: LocationManager = ctx.getSystemService(Context.LOCATION_SERVICE) as LocationManager

    var latitude by remember { mutableStateOf(0.0) }
    var longitude by remember { mutableStateOf(0.0) }

    var tracking by remember { mutableStateOf(false) }

    var btnTextEnabled = if (tracking) "Ein" else "Aus"

    var locationListener: LocationListener? = null

    locationListener = object : LocationListener {
        override fun onLocationChanged(location: Location) {
            latitude = location.latitude
            longitude = location.longitude
            gpsList.add(System.currentTimeMillis().toString()+","+latitude+","+longitude+"\n")
        }
    }

    Button(onClick = { tracking = !tracking }) {
        Text(text = "GPS-Tracking: $btnTextEnabled")
    }

    DisposableEffect(tracking) {
        if (tracking) {
            Log.d("GPS-Tracking", "Tracking wird gestartet")
            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 0f, locationListener as LocationListener
            )
            Log.d("GPS-Tracking", "Longitiude: $longitude\nLatitude: $latitude")
        } else {
            Log.d("GPS-Tracking", "Tracking wird gestoppt")
            locationManager.removeUpdates(locationListener as LocationListener)
            locationListener = null
        }

        onDispose {
            // Cleanup, if necessary
        }
    }
}

我试着用布尔变量tracking来控制跟踪。如果为真，则应开始跟踪，如果为假，则应停止跟踪。
但是当我试图停止跟踪时，它仍然在跟踪位置。你能看出我代码中的错误并给我给予吗？
