Installation

root build.gradle

allprojects {
    repositories {
        mavenCentral()
    }
}

project build.gradle

dependencies {
    commonMainApi("dev.icerock.moko:geo:0.6.0")

    // Compose Multiplatform
    commonMainApi("dev.icerock.moko:geo-compose:0.6.0")
}

Usage

in common code:

class TrackerViewModel(
    val locationTracker: LocationTracker
) : ViewModel() {

    init {
        viewModelScope.launch {
            locationTracker.getLocationsFlow()
                .distinctUntilChanged()
                .collect { println("new location: $it") }
        }
    }

    fun onStartPressed() {
        viewModelScope.launch { locationTracker.startTracking() }
    }

    fun onStopPressed() {
        locationTracker.stopTracking()
    }
}

In Android:

// create ViewModel
val locationTracker = LocationTracker(
    permissionsController = PermissionsController(applicationContext = applicationContext)
)
val viewModel = TrackerViewModel(locationTracker)

// bind tracker to lifecycle
viewModel.locationTracker.bind(lifecycle, this, supportFragmentManager)

In iOS:

let viewModel = TrackerViewModel(
    locationTracker: LocationTracker(
        permissionsController: PermissionsController(),
        accuracy: kCLLocationAccuracyBest
    )
)
