Yes, the package is called "iota". It works on the following platforms: - Flutter for dart projects - dart2js compatible browsers (it includes an optional build feature) - Desktop browsers for Dartium via Electron, Microsoft Windows 10 or OS X El Capitan. Furthermore it can run on mobile devices but not with the latest iOS updates since iota doesn't work with CIDER due to Apple's restrictions blocking loading of 3rd party javascript interfaces. Simply sideloading IOTA using fabric would get around that obstacle though.
