React native drawer not opening on swipe over map

Question

I am using react-native-navigation to start a single screen app that contains a Google map using - react-native-maps and a left drawer:

Navigation:

Navigation.startSingleScreenApp({
        screen: {
            screen : 'map.MapScreen',
            title : 'Map',
            navigatorStyle: {
                navBarHidden: true
            }
        },
        drawer : {
            left : {
                screen : 'drawer.DrawerScreen',
                passProps: {}
            },
            disableOpenGesture: true
        },
        animationType: 'slide-down',
        passProps: {}
    })

MapScreen:

export default class MapScreen extends Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <View style={styles.container}>
                <MapView
                    style={styles.map}
                    provider={PROVIDER_GOOGLE}>
                </MapView>
            </View>
        )
    }



}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
        zIndex: -1
    },
    map: {
        ...StyleSheet.absoluteFillObject,
    },
});

Unfortunately if I try to open the drawer, by swiping to the right, over the map, it won't open.

Does anyone have any idea on how to fix this?

You can use an overlay to add some invisible edge on the side of the map that does capture the gesture for opening the drawer. looks something like this:

const Screen = {
  width: Dimensions.get('window').width,
  height: Dimensions.get('window').height,
};
class Foo extends React.Component<Props, object> {
  render() {
    return (
      <View style={styles.container}>
        <MapView
          style={styles.mapContainer}
        />
        <View style={styles.mapDrawerOverlay} />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  mapContainer: {
    width: Screen.width,
    height: Dimensions.get('window').height,
  },
  mapDrawerOverlay: {
    position: 'absolute',
    left: 0,
    top: 0,
    opacity: 0.0,
    height: Dimensions.get('window').height,
    width: 10,
  },
});

This will use an overlay that is transparent and covers a small fraction of the map view. Beginning a drag-gesture in this area now can trigger the drawer.

Do not use ...StyleSheet.absoluteFillObject on your map styles. Doing this will resolve your issue

const React = require("react-native");

const { StyleSheet, Dimensions } = React;
const { width, height } = Dimensions.get("window");
export default {

  map: {
    width: width,
    height: height
  }
};

You need to activate ToggleDrawer() when you hit the side of the map which is covered by a thin TouchableOpacity window. here is the example code in homeview. make sure to bring in props as a variable to your function.

import React from 'react';
import {View, Text, SafeAreaView, StyleSheet, Dimensions, TouchableOpacity} from 'react-native';

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

const HomeScreen = (props) => {

    
    
    return(
        <SafeAreaView style = {{flex: 1}}>
            <View style = {styles.container}>
            <MapView
          style={styles.mapStyle}
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
            }
          />
        </MapView>
        <TouchableOpacity style = {styles.mapDrawerOverlay} onPress = {() => {
                    props.navigationProps.toggleDrawer();}
         } />
            </View>
        </SafeAreaView>
    );
};

export default HomeScreen;


  const styles = StyleSheet.create({
    container: {
      position: 'absolute',
      top: 0,
      left: 0,
      right: 0,
      bottom: 0,
      alignItems: 'center',
      justifyContent: 'flex-end',
    },
    mapDrawerOverlay:{
        position: 'absolute',
        left: 0,
        top: 0,
        opacity: 0.0,
        height: Dimensions.get('window').height,
        width:10,

    },
    mapStyle: {
      position: 'absolute',
      top: 0,
      left: 0,
      right: 0,
      bottom: 0,
    },
  });
