For the 1.9 release, Flutter’s web support has been merged (“unforked”) into the main repo. Web support hasn’t reached beta, and is not ready to be used in production. Web and desktop support (which is also coming), will impact the website, which was originally written exclusively for developing Flutter mobile apps. Some website updates are available now (and listed below), but more will be coming.
