Flutter 1.9 正式发布!

Flutter 1.9 is live!

更多信息,请查看 本文,和 1.9.1 的 发行注记

For more information, see Flutter news from GDD China: uniting Flutter on web and mobile, and introducing Flutter 1.9 and the 1.9.1 release notes.

随着 1.9 版本的发布,在 Web 平台运行 Flutter 的代码正式被合并到主 repo,但是 在 Web 平台的支持尚未达到 Beta 阶段,请不要用在生产环节。 Web 和即将到来的桌面端支持将会影响本站的内容,如下列出了一些更新,更多的更新将会在稍后时间发布:

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.
