Navigate the intersection of history, art, and culture. Wonderous will educate and entertain as you uncover information about some of the most famous structures in the world.

Built by gskinner in partnership with the Flutter team, Wonderous deliberately pushes visual fidelity, effects and transitions to showcase what Flutter is truly capable of on modern mobile hardware.

In addition to forking and reviewing the MIT licensed code available here, you can check out more information on the Wonderous Showcase Website.

App Downloads

To try the app you can download it from your favorite app store:


If you’re new to Flutter the first thing you’ll need is to follow the setup instructions.

Once Flutter is setup, you can use the latest beta channel:

  • flutter channel beta
  • flutter upgrade

Once on beta you’re ready to run the app on your local device or simulator:

  • flutter run -d ios
  • flutter run -d android

Impeller Rendering Layer

Impeller is Flutter’s next-generation rendering layer, that takes full advantage of modern hardware-accelerated graphics APIs. It is currently available as an early adopter preview, but is not yet feature-complete or fully optimized.

The version of Wonderous available in the iOS app store uses Impeller, but by default this code base does not. If you’d like to enable Impeller for iOS, follow these steps:

Edit the Info.plist file and set FLTEnableImpeller to true:


Then, switch to the master channel and build as normal:

  • flutter channel master
  • flutter upgrade
  • flutter run -d ios

Note: Currently, when Impeller is enabled testing in Simulator will not work, you will need to test on a physical device.
