Butterfly
WARNING: This is highly experimental
DISCLAIMER: This is a personal project. This is not an official Google product.
What is Butterfly?
A web framework heavily inspired by Flutter.
The goal of the project is conceptual and language compatibility with
Flutter. An explicit non-goal is "write once, run anywhere". Butterfly
intentionally shares no code with Flutter. However, because of the same
language and framework architecture, many of the skills, tools, libraries
and platform-independent code can be shared with Flutter apps.
What's included?
- A widget system almost identical to that of Flutter
- Flutter-like development mode:
- Debug code inside your IDE
- Hot-reload!
Who is Butterfly for?
- For app developers who build mobile apps using Flutter, and who also need
to build web apps. Butterfly gives you a single conceptual model for writing
your apps for both web and mobile, and allows the reuse of big chunks of code.
- For Flutter developers who need to run parts of their app within a WebView.
- For Dart developers who prefer functional-reactive programming style.
Plays nice with
- Flutter - source of inspiration
- Greencat - Redux for Dart
- RxDart - reactive extensions for Dart
- TODO: Custom elements -
Butterfly does not include
dart:html. If you need to drop down below the
framework and access the DOM API directly, consider using custom elements.
