React Native Maps: Markers image doesn't show using Custom Marker in react-native-maps

I'm using react-native-maps but I faced a problem that after a lot of googling without answer makes me ask it here. I'm trying to use Custom Marker for the marker in the map as the following picture

enter image description here

  • as I searched I found out that needed to use Custom Marker to accomplish the maker's design, then I created a Custom Marker component

    import React, { Component } from "react";
    import { View } from "react-native";
    import {
    Text,
    Left,
    Right,
    Thumbnail,
    } from "native-base";
    const defaultEmployeeLogo = require("../../../assets/defualtEmployee.png");
    class CustomMarker extends Component {
    render() {
        return (
        <View style={{ flexDirection: 'row', width: 140, height: 60, 
          borderRadius: 70, backgroundColor: 'orange' }}>
            <Left>
                <Thumbnail source={defaultEmployeeLogo} />
            </Left>
            <Right>
                <Text style={{
                    color: '#fef',
                    fontSize: 13,
                    paddingBottom: 2,
                    fontFamily: 'Roboto',
                    alignItems: 'center',
                    paddingRight: 10
                }}>Mohammad</Text>
            </Right></View >);
       }
    }
    export default CustomMarker;
    

when I use CustomMarker.js class solely it works fine and it shows the image but when I use it as the marker custom view it doesn't show the image

enter image description here

I don't know why it can't render the image with Custom Marker in android. and here is my code where I'm using map, markers and custom marker class

return (
  <View style={styles.map_container}>
    <MapView
      style={styles.map}
      customMapStyle={customrMapStyle}
      region={{
        latitude: this.state.region.latitude,
        longitude: this.state.region.longitude,
        latitudeDelta: 0.4,
        longitudeDelta: 0.41,
      }} >
      {
        coordinationData.map(function (marker, i) {

          let lat = marker.latLang.latitude;
          let lang = marker.latLang.longitude;
           <MapView.Marker
            key={i}
            coordinate={
              {
                latitude: lat,
                longitude: lang,
                latitudeDelta: 0.4,
                longitudeDelta: 0.41
              }
            }
            title={marker.title}
            description={marker.description}

          >
            <CustomMarker />
          </MapView.Marker>
        })}
    </MapView>
  </View>

any kind of help would be appreciated.

Use SVG for this https://github.com/react-native-community/react-native-svg

<Marker
    coordinate={{
        longitude: lang,
        latitude: lat,
    }}
>
    <View style={{
        flexDirection: 'row', width: 100, height: 30,
        backgroundColor: 'orange'
    }}>
        <Svg
            width={40} height={30}>
            <Image
                href={url}
                width={40}
                height={30}
            />
        </Svg>
        <View
            style={{
                flexDirection: 'column'

            }}
        >
            <Text
                style={{
                    marginLeft: 2,
                    fontSize: 9,
                    color: '#ffffff',
                    fontWeight: 'bold',
                    textDecorationLine: 'underline'
                }}
            >{marker.title}</Text>
            <Text
                style={{
                    marginLeft: 2,
