react native maps marker custom image cannot change from default

Question

I've spent about 5 hours trying to get this to work with many different permutations of code, and then rebuilding. I cannot for the life of me change the default "red pointer" marker as the default marker image in react native maps.

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

...

<MapView
    provider={PROVIDER_GOOGLE}
    style={styles.map}
    ref={ref => {this.map = ref;}}
    minZoomLevel={4}  // default => 0
    maxZoomLevel={10} // default => 20
    enableZoomControl={true}
    showsUserLocation = {true}
    showsMyLocationButton = {true}
    zoomEnabled = {true}
    initialRegion={{
        latitude: 37.600425,
        longitude: -122.385861,
        latitudeDelta: LATITUDE_DELTA,
        longitudeDelta: LONGITUDE_DELTA,
    }}
>
    <MapView.Marker
        coordinate={marker.location}
        image={require('./images/test.png')}        <------ HERE
        width={48}
        height={48}
    />
</MapView>

The images definitely exist in the right folder, I've tried different image formats png/gif/jpg/svg, I've tried using {{uri:...}} and icon/image, adding and removing width/height attributes. Nothing seems to work. I'm always getting the default red pointer.

Have I missed something obvious?

The project packager/compiler fails when I require an image that doesn't exist, or an unsupported type. It definitely can see the image, but just doesn't do anything with it. Same results on the emulator and on actual device.

image={require('./images/test.png')}

This line just does nothing, as if it's being ignored somehow.

<MapView
    provider={PROVIDER_GOOGLE}
    style={styles.container}
    region={{
        latitude: this.state.latitude,
        longitude: this.state.longitude,
    }}
    >

    <Marker
      coordinate={{
        latitude: this.state.latitude,
        longitude: this.state.longitude,
      }}
      description={"This is a marker in React Natve"}
      >

      <Image source={require('./man_marker.png')} style={{height: 35, width:35 }} />

    </Marker>

</MapView>

Answer 2

There are two solutions:

The first solution (recommended)

Resize your marker image with image editor(such as Photoshop,....) and use as icon in marker

To do this, you can make three photos of different sizes (YOUR_MARKER.png , YOUR_MARKER@2x.png , YOUR_MARKER@3x.png) (React Native automatically displays the appropriate item).

This is a good solution if you have a large number of markers.(You can refer here to clarify this)

<Marker
    coordinate={ ... }
    tracksViewChanges={false}
    icon={require('./YOUR_MARKER.png')}
/>

The second solution

As @shubham-raitka said you can use the Image inside the marker

<Marker
    coordinate={ ... }
>
    <Image source={require('./YOUR_MARKER.png')} style={{height: 35, width:35 }} />

</Marker>

In this case, if your number of markers is high (about 50 or more) the map performance will be very low.Therefore, it is not recommended to use this method

Answer 3

Here's an approach that worked for me in a similar situation: Use Image in place of Marker. Pop-ups work the same as with a marker. If you try this, Image is imported from react-native. The actual image is imported as:

var dotImage = require('./pathToImage.png')

<Marker
  coordinate={meter.latlng}
  title={"Parking Meter"}
  key={idx}
 >
<Image
    source={dotImage}
    style={{height: 6, width: 6}}
 />
 </Marker>

Answer 4

The way you give the width and height is a bit strange, please try with this way.

import MapView, { Marker, PROVIDER_GOOGLE } from 'react-native-maps';

const markerImg = require('./images/test.png'); // <-- create a const with the path of the image

<------
------>
<MapView
    provider={PROVIDER_GOOGLE}
    style={styles.map}
    ref={ref => {this.map = ref;}}
    minZoomLevel={4}  // default => 0
    maxZoomLevel={10} // default => 20
    enableZoomControl={true}
    showsUserLocation = {true}
    showsMyLocationButton = {true}
    zoomEnabled = {true}
    initialRegion={{
      latitude: 37.600425,
      longitude: -122.385861,
      latitudeDelta: LATITUDE_DELTA,
      longitudeDelta: LONGITUDE_DELTA,
    }}
>
<Marker
    image={markerImg} // <----- add this the const with image
    onPress={() => this.setState({ marker1: !this.state.marker1 })}
    coordinate={{
        latitude: 37.600425,
        longitude: -122.385861,
    }}
    centerOffset={{ x: -18, y: -60 }}
    anchor={{ x: 0.69, y: 1 }}
/>
</Marker>
</MapView>

I hope it works for you, works for me!

Answer 5

Not enough rep yet to just leave a comment, but the first solution works, I just had to add resizeMode or it cuts off the image if it's bigger.

<Marker
    coordinate={ ... }
>
    <Image source={require('./YOUR_MARKER.png')} style={{height: 35, width:35, resizeMode:"contain" }} />

</Marker>

Answer 6

 <Marker
   coordinate={d.driverLocation}
   title={d.driverName}
   description={d.autoNumber}
   onPress={() => console.warn(d.mobaNumbers)}
   image={require("../../../assets/bee.png")}
 >
 </Marker>

Answer 7

Try this it should work

import {Image} from 'react-native';
import MapView, {Marker} from 'react-native-maps';

        <MapView
          style={styles.mapStyle}
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
          customMapStyle={mapStyle}>
          <Marker
            draggable
            coordinate={{
              latitude: 37.78825,
              longitude: -122.4324,
            }}
            onDragEnd={e => alert(JSON.stringify(e.nativeEvent.coordinate))}
            title={'Test Marker'}
            description={'This is a description of the marker'}>
            <Image
              source={require('./assests/custom_marker.png')}
              style={{height: 35, width: 35}}
            />
          </Marker>
        </MapView>
