Progressive Web App (PWA) for Dart #
Progressive web apps (PWA) are a hybrid of regular web pages
(or websites) and a mobile application. This new application
model attempts to combine features offered by most modern
browsers with the benefits of mobile experience.
Warning: the API is experimental, and subject to change.
Background #
PWA is using ServiceWorkers:
