ERROR TypeError: Cannot read property 'getPreferences' of undefined

i confirm the plugin works fine and its @ionic-native/app-rate issue
use the AppRate object from window and it should work as expected

    // tslint:disable-next-line: no-string-literal
    const appRate: any = window['AppRate'];
    const preferences = appRate.getPreferences();
    preferences.simpleMode = true;
    preferences.storeAppURL = {
      ios: 'id123456789',
      android: 'market://details?id=com.example.app',
      windows: 'ms-windows-store://review/?ProductId=XXXXXXXX',
    };
    appRate.setPreferences(preferences);
    appRate.promptForRating(true);

possible reference #291
