This is my code:

import { StyleSheet, Text, View, Button } from "react-native";
import React, { useEffect } from "react";
import { LatLng, LeafletView } from "react-native-leaflet-view";

export default function Home({ navigation }) {

  return (
    <View style={styles.container}>
      <View style={styles.myMap}>
        <LeafletView
          mapLayers={[
            {
              baseLayerName: "MapTiler",
              baseLayerIsChecked: "true",
              baseLayer: "true",
              url: "https://a.tile.openstreetmap.de/tiles/osmde/{z}/{x}/{y}.png",
            },
          ]}
        />
      </View>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#ffd",
    alignItems: "center",
    justifyContent: "center",
  },
  myMap: {
    flex: 2,
    backgroundColor: "white",
    width: "100%",
    marginTop: 30,
    marginBottom: 30,
  },
  map: {
    width: "100%",
    height: "100%",
  },
});

Are you using Expo with the external App by any chance (see #12)? If not: did you run npm run android?

[BasselTurky]

I am using Expo, I tried npm run android but still same error.

[BasselTurky]

Should I eject from Expo?

[miallo]

So far I have only tried it with an ejected Expo app and that is working perfectly. Though I think if I understood the others correctly it also works with Expo, but just not with the QR code and the Expo App

I started new project on React Native CLI and it worked but had to install react-native-webview library first
