What This Article Covers
Flutter developers hit a wall when trying to build traditional web applications. They needed a web framework written in Dart that would fit naturally with Flutter's approach.
The Flutter team chose Jaspr, a DOM-based HTML/CSS framework built by Kilian in Dart. They moved their documentation sites, dart.dev and docs.flutter.dev, over to it.
Jaspr is now the official documentation platform for Flutter and Dart. It shows that Dart-based frameworks can work just as well as traditional web tools for building websites.
