Null exception when querying for app version

[ashwin-dailype]

Summary

When using getInstalledApps() method to get the installed apps on my device, I'm getting a null exception inside the models.dart file where fromJson method looks for the version key in this line. https://github.com/vishesh005/app_utils/blob/c6c24d4c60a23965b53fd1c3db49c4578529759c/lib/models.dart#L15

Code

This is the code I wrote using the package

  List<BundleInfo> apps = await AppUtils.getInstalledApps();
  List<Map<String, String>> finalList = [];
  for (var element in apps) {
    finalList.add({
      'name': element.appName,
      'package': element.appIdentifier,
      'version': element.version,
    });
  }

I will keep this open until the fix is applied to pub.dev.
