<MapView /> Component API

Props

Prop	Type	Default	Note
provider	string		The map framework to use. Either "google" for GoogleMaps, otherwise null or undefined to use the native map framework (MapKit in iOS and GoogleMaps in android).
region	Region		The region to be displayed by the map. The region is defined by the center coordinates and the span of coordinates to display.
initialRegion	Region		The initial region to be displayed by the map. Use this prop instead of region only if you don't want to control the viewport of the map besides the initial region. Changing this prop after the component has mounted will not result in a region change. This is similar to the initialValue prop of a text input.
liteMode	Boolean	false	Enable lite mode. Note: Android only.
mapType	String	"standard"	The map type to be displayed. - standard: standard road map (default) - satellite: satellite view - hybrid: satellite view with roads and points of interest overlayed - terrain: (Android only) topographic view
customMapStyle	Array		Adds custom styling to the map component. See README for more information.
showsUserLocation	Boolean	false	If true the app will ask for the user's location. NOTE: You need to add NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation, otherwise it is going to fail silently!
userLocationAnnotationTitle	String		The title of the annotation for current user location. This only works if showsUserLocation is true. There is a default value My Location set by MapView. Note: iOS only.
followsUserLocation	Boolean	false	If true the map will focus on the user's location. This only works if showsUserLocation is true and the user has shared their location. Note: iOS only.
showsMyLocationButton	Boolean	true	If false hide the button to move map to the current user's location.
showsPointsOfInterest	Boolean	true	If false points of interest won't be displayed on the map.
showsCompass	Boolean	true	If false compass won't be displayed on the map.
showsScale	Boolean	true	A Boolean indicating whether the map shows scale information.
showsBuildings	Boolean	true	A Boolean indicating whether the map displays extruded building information.
showsTraffic	Boolean	true	A Boolean value indicating whether the map displays traffic information.
showsIndoors	Boolean	true	A Boolean indicating whether indoor maps should be enabled.
showsIndoorLevelPicker	Boolean	false	A Boolean indicating whether indoor level picker should be enabled. Note: Android only.
zoomEnabled	Boolean	true	If false the user won't be able to pinch/zoom the map.
rotateEnabled	Boolean	true	If false the user won't be able to pinch/rotate the map.
scrollEnabled	Boolean	true	If false the user won't be able to change the map region being displayed.
pitchEnabled	Boolean	true	If false the user won't be able to adjust the camera’s pitch angle.
toolbarEnabled	Boolean	true	Android only If false will hide 'Navigate' and 'Open in Maps' buttons on marker press
cacheEnabled	Boolean	false	If true map will be cached and displayed as an image instead of being interactable, for performance usage.
loadingEnabled	Boolean	false	If true a loading indicator will show while the map is loading.
loadingIndicatorColor	Color	#606060	Sets loading indicator color, default to #606060.
loadingBackgroundColor	Color	#FFFFFF	Sets loading background color, default to #FFFFFF.
moveOnMarkerPress	Boolean	true	Android only If false the map won't move when a marker is pressed.
legalLabelInsets	EdgeInsets		If set, changes the position of the "Legal" label link from the OS default. Note: iOS only.

Events

To access event data, you will need to use e.nativeEvent. For example, onPress={e => console.log(e.nativeEvent)} will log the entire event object to your console.

Event Name	Returns	Notes
onRegionChange	Region	Callback that is called continuously when the region changes, such as when a user is dragging the map.
onRegionChangeComplete	Region	Callback that is called once when the region changes, such as when the user is done moving the map.
onPress	{ coordinate: LatLng, position: Point }	Callback that is called when user taps on the map.
onPanDrag	{ coordinate: LatLng, position: Point }	Callback that is called when user presses and drags the map. NOTE: for iOS scrollEnabled should be set to false to trigger the event
onLongPress	{ coordinate: LatLng, position: Point }	Callback that is called when user makes a "long press" somewhere on the map.
onMarkerPress		Callback that is called when a marker on the map is tapped by the user.
onMarkerSelect		Callback that is called when a marker on the map becomes selected. This will be called when the callout for that marker is about to be shown. Note: iOS only.
onMarkerDeselect		Callback that is called when a marker on the map becomes deselected. This will be called when the callout for that marker is about to be hidden. Note: iOS only.
onCalloutPress		Callback that is called when a callout is tapped by the user.
onMarkerDragStart	{ coordinate: LatLng, position: Point }	Callback that is called when the user initiates a drag on a marker (if it is draggable)
onMarkerDrag	{ coordinate: LatLng, position: Point }	Callback called continuously as a marker is dragged
onMarkerDragEnd	{ coordinate: LatLng, position: Point }	Callback that is called when a drag on a marker finishes. This is usually the point you will want to setState on the marker's coordinate again

Methods

Method Name	Arguments	Notes
animateToRegion	region: Region, duration: Number
animateToCoordinate	coordinate: LatLng, duration: Number
fitToElements	animated: Boolean
fitToSuppliedMarkers	markerIDs: String[], animated: Boolean	If you need to use this in ComponentDidMount, make sure you put it in a timeout or it will cause performance problems.
fitToCoordinates	coordinates: Array<LatLng>, options: { edgePadding: EdgePadding, animated: Boolean }	If called in ComponentDidMount in android, it will cause an exception. It is recommended to call it from the MapView onLayout event.
