Flutter Gallery is a resource to help developers evaluate and use Flutter. It is a collection of Material Design & Cupertino widgets, behaviors, and vignettes implemented with Flutter. We often get asked how one can see Flutter in action, and this gallery demonstrates what Flutter provides and how it behaves in the wild.
Flutter Gallery has been built to support multiple platforms. This includes:
That being said, extra steps must be taken to enable Desktop support. For example, to run the macOS app:
cd gallery/ flutter config --enable-macos-desktop flutter create . flutter run -d macos
Additionally, the UI adapts between mobile and desktop layouts regardless of the platform it runs on. This is determined based on window size as outlined in adaptive.dart.
Convert your animation to a
.gif file. Ideally, use a background color of
0xFF030303 to ensure the animation blends into the background of the app.
Add your new
.gif file to the assets directory under
assets/splash_effects. Ensure the name follows the format
splash_effect_$num.gif. The number should be the next number after the current largest number in the repository.
Update the map
_effectDurations in splash.dart to include the number of the new
.gif as well as its estimated duration. The duration is used to determine how long to display the splash animation at launch.
