## Features
- **Geolocation tracking** - track user geolocation from common code;
- **Compose Multiplatform** support;

## Requirements
- Gradle version 6.0+
- Android API 16+
- iOS version 9.0+

## Installation
root build.gradle  
```groovy
allprojects {
    repositories {
        mavenCentral()
    }
}
```

project build.gradle
```groovy
dependencies {
    commonMainApi("dev.icerock.moko:geo:0.8.0")

// Compose Multiplatform
    commonMainApi("dev.icerock.moko:geo-compose:0.8.0")
}
```

## Usage
in common code:
```kotlin
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:
```kotlin
// create ViewModel
val locationTracker = LocationTracker(
    permissionsController = PermissionsController(applicationContext = applicationContext)
)
val viewModel = TrackerViewModel(locationTracker)

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

In Android jetpack compose:
```kotlin
// create ViewModel
val locationTracker = LocationTracker(
    permissionsController = PermissionsController(applicationContext = applicationContext)
)
val viewModel = TrackerViewModel(locationTracker)

// bind tracker to composable
BindLocationTrackerEffect(locationTracker = tracker)
```

In iOS:
```swift
let viewModel = TrackerViewModel(
    locationTracker: LocationTracker(
        permissionsController: PermissionsController(),
        accuracy: kCLLocationAccuracyBest
    )
)
```

## Samples
Please see more examples in the [sample directory](sample).

## Set Up Locally 
- The [geo directory](geo) contains the `geo` library;
- In [sample directory](sample) contains sample apps for Android and iOS; plus the mpp-library connected to the apps.

## Contributing
All development (both new features and bug fixes) is performed in the `develop` branch. This way `master` always contains the sources of the most recently released version. Please send PRs with bug fixes to the `develop` branch. Documentation fixes in the markdown files are an exception to this rule. They are updated directly in `master`.

The `develop` branch is pushed to `master` on release.

For more details on contributing please see the [contributing guide](CONTRIBUTING.md).

Before send PR please run checks on local:
- `./local-check.sh` in root of repository
- `./local-check.sh` in `sample` directory
