<Geojson /> Component API

Props

Prop Type Default Note
geojson GeoJSON Geojson description of object.
strokeColor String stroke property in GeoJson if present else #000 The stroke color to use for polygons and polylines.
fillColor String fill property in GeoJson The fill color to use for polygons.
strokeWidth Number stroke-width property in Geojson if present else 1 The stroke width to use for polygons and polylines.
color String marker-color property in GeoJson The color to use for points.
lineDashPhase Number (iOS only) The offset (in points) at which to start drawing the dash pattern. Use this property to start drawing a dashed line partway through a segment or gap. For example, a phase value of 6 for the patter 5-2-3-2 would cause drawing to begin in the middle of the first gap.
lineDashPattern Array<Number> An array of numbers specifying the dash pattern to use for the path. The array contains one or more numbers that indicate the lengths (measured in points) of the line segments and gaps in the pattern. The values in the array alternate, starting with the first line segment length, followed by the first gap length, followed by the second line segment length, and so on.
lineCap `'butt' 'round' 'square'`
lineJoin `'miter' 'round' 'bevel'`
miterLimit Number The limiting value that helps avoid spikes at junctions between connected line segments. The miter limit helps you avoid spikes in paths that use the miter lineJoin style. If the ratio of the miter length—that is, the diagonal length of the miter join—to the line thickness exceeds the miter limit, the joint is converted to a bevel join. The default miter limit is 10, which results in the conversion of miters whose angle at the joint is less than 11 degrees.
zIndex Number Layer level of the z-index value
onPress Function returns the selected overlay value with the onPress functionality
markerComponent React Node Component to render in place of the default marker when the overlay type is a point
title string The title of the marker. This is only used if the component has no children that are a <Callout />
tracksViewChanges Boolean true Sets whether this marker should track view changes. It's recommended to turn it off whenever it's possible to improve custom marker performance. This is the default value for all point markers in your geojson data. It can be overriden on a per point basis by adding a trackViewChanges property to the properties object on the point.

Example

import React from 'react';
import MapView, {Geojson} from 'react-native-maps';

const myPlace = {
  type: 'FeatureCollection',
  features: [
    {
      type: 'Feature',
      properties: {},
      geometry: {
        type: 'Point',
        coordinates: [64.165329, 48.844287],
      }
    }
  ]
};

const Map = props => (
  <MapView>
    <Geojson 
      geojson={myPlace} 
      strokeColor="red"
      fillColor="green"
      strokeWidth={2}
    />
  </MapView>
);
