Element type is invalid: expect a string-CodePudding

I'm trying to use an AppBar from React Native Material. The icon i use in the IconButton is from react-native-vector-icon. I have no idea why I'm getting error saying Element type is invalid: expect a string. Check the render method for IconButton as I literally copied the exact code from the React Native Material official doc.

import {AppBar, IconButton} from '@react-native-material/core';
import {Icon} from 'react-native-vector-icons/Entypo';

      <AppBar
        title="Title"
        leading={props => (
          <IconButton
            icon={props => <Icon name="menu" {...props} />}
            {...props}
          />
        )}
      />
