The TimeZone package does work. From the issues list on GitHub:

Sorry this took 6 months but I have a good solution. I think it will be the recommended solution.

See Flutter's docs on Adding Assets. You should be able to add to your Flutter app's pubspec.yaml:

flutter:
  assets:
    - packages/timezone/lib/data/2015b.tzf

and load in your app with:

Future> loadDefaultData() async {
  var byteData = await rootBundle.load('packages/timezone/data/2015b.tzf');
  return byteData.buffer.asUint8List();
}

// Call the above with something like:

loadDefaultData().then((rawData) {
  initializeDatabase(rawData);
  var zurich = getLocation('Europe/Zurich');
});
