Google Flutter GDE

As Flutter GDE, turned to WebF because our project demanded high performance and true runtime dynamism. With WebF, we gained the flexibility to drive UI updates dynamically—while still enjoying the smooth, polished UX our users expect from Flutter. The experience? We could ship new features far more rapidly, reuse web-ecosystem patterns, and yet deliver an app that feels as native and performant as if we wrote every component in Dart. For anyone balancing dynamic content needs and Flutter-grade performance, WebF delivers on both fronts. 

Features

Modern web tech stacks and CSS work seamlessly in WebF.
