'How do I set a marker in MapView of React Native

I want to set a marker on MapView in React Native, but I can't find any information through official documents of MapView.
If it is not allowed in that way, how can I use existed react module such as react-googlemaps in React Native?

Solution 1:^[1]

Thank you @naoufal. Finally I am able to display markers on map for react native IOS.

<View style={styles.container}>
        <MapView style={styles.map}
          initialRegion={{
              latitude: 37.78825,
              longitude: -122.4324,
              latitudeDelta: 0.0,
              longitudeDelta: 0.0,
          }}
        >
        <MapView.Marker
            coordinate={{latitude: 37.78825,
            longitude: -122.4324}}
            title={"title"}
            description={"description"}
         />
      </MapView>
 </View>

For map and container styles, I have used following styles:

 var styles = StyleSheet.create({

  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
    map: {
      position: 'absolute',
      top: 0,
      left: 0,
      right: 0,
      bottom: 0,
    }
});

    }}
    >
        <Marker coordinate = {{latitude: 37.78825,longitude: -122.4324}}
         pinColor = {"purple"} // any color
         title={"title"}
         description={"description"}/>
    </MapView>
</View>

For those looking for a dynamic (e.g., from API), rather than hardcoded coordinates; here's the copy/paste snippet from one of the screens automatically generated by Expo CLI, included React Hooks:

import axios from "axios";
import MapView from "react-native-maps";
import { Dimensions, StyleSheet } from "react-native";
import { Marker } from "react-native-maps";
import { Text, View } from "../components/Themed";

export default function TabTwoScreen() {
  const [markers, setMarkers] = useState(null);

  useEffect(() => {
    axios({
      method: "GET",
      url: "https://API_URL...",
      headers: {
        Authorization: `Bearer MY_TOKEN_ABC123...`,
        Accept: "application/json",
      },
    })
      .then((response) => {
        setMarkers(response.data.results);
      })
      .catch((error) => {
        console.log(error);
      });
  }, []); // "[]" makes sure the effect will run only once.

  return (
    <View style={styles.container}>
      <Text style={styles.title}>Tab Two</Text>
      <MapView style={styles.map}>
        {markers &&
          markers.map((marker: any, index: number) => (
            <Marker
              key={index}
              coordinate={{
                latitude: marker.location[1],
                longitude: marker.location[0],
              }}
              title={marker.title}
              description={marker.description}
            />
          ))}
      </MapView>
    </View>
  );
}

const styles = StyleSheet.create({
  // Add your styles here...
});

Updated code - 2020 | React Native 0.63

import MapView, { Marker } from "react-native-maps";
<MapView
    style={styles.mapStyle}
    region={{
        latitude: this.state.mapLat,
        longitude: this.state.mapLong,
        latitudeDelta: 0.001663,
        longitudeDelta: 0.002001,

    <Marker

    >
    </Marker>
</MapView>

According to this issue, it's not exposed yet. You won't be able to use the web-React package either, React Native doesn't work like that.

Two suggestions:

Wait for the above issue to be resolved to get a proper API
Try and use WebView to link to a Google Map with an annotation

I'm not actually certain whether #2 is possible though.

import MapView from 'react-native-maps';
<View style={StyleSheet.absoluteFillObject}>
        <MapView style={styles.map}
          showsUserLocation //to show user current location when given access
          loadingEnabled //to show loading while map loading

             locations && locations.map((location, index) => {
                   const {
                       coords: { latitude, longitude }
                          } = location;

const styles = StyleSheet.create({

map: {
  position: 'absolute',
  top: 0,
  left: 0,
  right: 0,
  bottom: 0,
}

Try using this. Hope it helps to mark for many locations. Happy Coding.

Thank you @zia_qureshi. Finally I am able to display markers on map for react native android.

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

const App = () => {
  const [region, setRegion] = useState({
    latitude: 51.5078788,
    longitude: -0.0877321,
    latitudeDelta: 0.009,
    longitudeDelta: 0.009
  });

  return (
    <MapView
      style={{ flex: 1 }}
      region={region}
      onRegionChangeComplete={region => setRegion(region)}
    >
      <Marker coordinate={{ latitude: 51.5078788, longitude: -0.0877321 }} />
    </MapView>
  );
};

export default App;
