I am trying to show native map using the coords from the example and I get an error:

*note using ios and real device for debugging

ERROR:

Could not inset compass from edges 9
Could not inset scale from edge 
Could not inset legal attribution from corner 4

CODE:

class Map extends Component {
constructor(props) {
    super(props);
}
render() {   
    console.log('map render')    
    return (
            <MapView 
            provider={null}
            initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
            }}
        />
    );
}}

Answer 1

it was a problem with styling. I was able to fix it with this code:

render() {
    return (
      <View style={styles.container}>
        <MapView
        style={styles.map}
          provider={null}
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
  },
});
