MapView backed by MapLibre Native

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
mapStyle	string | object	none	false	Style for map - either a URL or a Style JSON (https://maplibre.org/maplibre-style-spec/). Default: StyleURL.Default
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

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.
logoPosition	{ top?: number; left?: number } | { top?: number; right?: number } | { bottom?: number; left?: number } | { bottom?: number; right?: number }	none	false	Adds logo offset, e.g. {top: 8, left: 8} will put the logo in top-left corner of the map

Methods

getPointInView(coordinate)

Converts a geographic coordinate to a pixel point of the view.

Arguments

Name	Type	Required	Description
coordinate	GeoJSON.Position	Yes	Geographic coordinate

const pointInView = await mapViewRef.current?.getPointInView([
  -37.81707, 144.949901,
]);

getCoordinateFromView(point)

Converts a pixel point of the view to a geographic coordinate.

Arguments

Name	Type	Required	Description
point	tuple	Yes	undefined

const coordinate = await mapViewRef.current?.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"],
);

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

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.
