Flutter 1.9 is live!
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.
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.
New and updated docs on the site include:
- We’ve revamped the Showcase page.
- The Flutter layout codelab has been rewritten and uses the updated DartPad, the browser-based tool for running Dart code. DartPad now supports Flutter! Try it out and let us know what you think.
- A new page on using the dart:ffi library to bind your app to native code (a feature currently under development).
- The Performance view tool, which allows you to record and profile a session from your Dart/Flutter application, has been enabled in DevTools. For more information, see the Performance view page.
- A new page on building a web application.
- A new page on creating responsive apps in Flutter.
- A new page on preparing a web app for release.
- A new web FAQ.
- The Flutter for web page is updated.
Other relevant docs:
- Error messages have been improved in SDK 1.9. For more information, read Improving Flutter’s Error Messages on the Flutter Medium publication.
- If you already have a web app that depends on the flutter_web package, the following instructions tell you how to migrate to the flutter package: Upgrading from package:flutter_web to the Flutter SDK.
- A new ToggleButtons widget, described in the API docs. ToggleButtons demo
- A new ColorFiltered widget, also described in the API docs. ColorFiltered demo
- New behavior for the SelectableText widget.
