Props

Prop Type Default Required Description
contentInset number[] | number none false The distance from the edges of the map view’s frame to the edges of the map view’s logical viewport.
style ViewProps["style"] none false Style for wrapping React Native View
styleURL string none false Style URL for map - notice, if non is set it will default to MapLibreGL.StyleURL.Default
styleJSON string none false StyleJSON for map - according to TileJSON specs: https://github.com/mapbox/tilejson-spec
preferredFramesPerSecond number none false iOS: The preferred frame rate at which the map view is rendered.
The default value for this property is MLNMapViewPreferredFramesPerSecondDefault,
which will adaptively set the preferred frame rate based on the capability of
the user’s device to maintain a smooth experience. This property can be set to arbitrary integer values.

Android: The maximum frame rate at which the map view is rendered, but it can't excess the ability of device hardware.
This property can be set to arbitrary integer values.
localizeLabels boolean false false Automatically change the language of the map labels to the system’s preferred language,
this is not something that can be toggled on/off
zoomEnabled boolean none false Enable/Disable zoom on the map
scrollEnabled boolean true false Enable/Disable scroll on the map
pitchEnabled boolean true false Enable/Disable pitch on map
rotateEnabled boolean true false Enable/Disable rotation on map
attributionEnabled boolean true false Enable/Disable attribution on map.

This must be enabled for Mapbox-hosted tiles and styles. Please refer to the Mapbox Terms of Service.
Other providers do not require this.
attributionPosition { top?: number; left?: number } | { top?: number; right?: number } | { bottom?: number; left?: number } | { bottom?: number; right?: number } none false Adds attribution offset, e.g. {top: 8, left: 8} will put attribution button in top-left corner of the map
tintColor string | unknown[] none false MapView's tintColor
logoEnabled boolean false false Enable/Disable the logo on the map.

Methods

getPointInView(coordinate)

Converts a geographic coordinate to a point in the given view’s coordinate system.

Arguments

Name Type Required Description
coordinate GeoJSON.Position Yes A point expressed in the map view's coordinate system. 
const pointInView = await this._map.getPointInView([-37.817070, 144.949901]);

getCoordinateFromView(point)

Converts a point in the given view’s coordinate system to a geographic coordinate.

Arguments

Name Type Required Description
point Array Yes A point expressed in the given view’s coordinate system. 
const coordinate = await this._map.getCoordinateFromView([100, 100]);

getVisibleBounds()

The coordinate bounds(ne, sw) visible in the users’s viewport.

const visibleBounds = await this._map.getVisibleBounds();

queryRenderedFeaturesAtPoint(point, [filter], [layerIDs])

Returns an array of rendered map features that intersect with a given point.

Arguments

Name Type Required Description
point tuple Yes undefined
filter FilterExpression No A set of strings that correspond to the names of layers defined in the current style. Only the features contained in these layers are included in the returned array.
layerIDs Array No A array of layer id's to filter the features by 
this._map.queryRenderedFeaturesAtPoint([30, 40], ['==', 'type', 'Point'], ['id1', 'id2'])

queryRenderedFeaturesInRect(bbox, [filter], [layerIDs])

Returns an array of rendered map features that intersect with the given rectangle,
restricted to the given style layers and filtered by the given predicate.

Arguments

Name Type Required Description
bbox GeoJSON.BBox Yes A rectangle expressed in the map view’s coordinate system.
filter FilterExpression No A set of strings that correspond to the names of layers defined in the current style. Only the features contained in these layers are included in the returned array.
layerIDs Array No A array of layer id's to filter the features by 
this._map.queryRenderedFeaturesInRect([30, 40, 20, 10], ['==', 'type', 'Point'], ['id1', 'id2'])

setCamera()

Map camera will perform updates based on provided config. Deprecated use Camera#setCamera.

takeSnap([writeToDisk])

Takes snapshot of map with current tiles and returns a URI to the image

Arguments

Name Type Required Description
writeToDisk Boolean No If true will create a temp file, otherwise it is in base64

getZoom()

Returns the current zoom of the map view.

const zoom = await this._map.getZoom();

getCenter()

Returns the map's geographical centerpoint

const center = await this._map.getCenter();

setSourceVisibility(visible, sourceId, [sourceLayerId])

Sets the visibility of all the layers referencing the specified sourceLayerId and/or sourceId

Arguments

Name Type Required Description
visible boolean Yes Visibility of the layers
sourceId string Yes Identifier of the target source (e.g. 'composite')
sourceLayerId String No Identifier of the target source-layer (e.g. 'building') 
await this._map.setSourceVisibility(false, 'composite', 'building')

showAttribution()

Show the attribution and telemetry action sheet.
If you implement a custom attribution button, you should add this action to the button.
