v2.12.0

Support for Flutter Profile and Release Modes

You can now create launch configurations for profile and release modes in Flutter apps. For now, this requires you to create a launch.json and add the setting there..

For more information on using profile and release modes, see Running Flutter Apps in Profile or Release Modes.

Flutter Memory Usage Monitoring

When running a profile build (or if you set showMemoryUsage in your launch configuration) the total memory for your applications heaps will be shown in the status bar.

Note: This is heap usage and not total process memory. In debug builds it may not be reflective of actual usage in a release build.

Progress Notifications for Long Running Tasks

Long running tasks like Flutter: Get Packages and Flutter builds will now show more obvious progress notifications with progress animations.

As part of this, these actions may also now be cancelled from the x in the notification.

Flutter Icons in Tooltips and Completion Descriptions

Flutter icons now show correctly in tooltips and completion descriptions instead of chunks of HTML.

Extract Widget Refactor

An Extract Widget refactor is now available on the lightbulb menu that creates a new Widget class and inserts a call to its constructor in the original position.

Extract Method Refactor

An Extract Method refactor is now available on the lightbulb menu.

Better Feedback for Failed Renames

Failed renames will now show errors directly in the editor instead of window-scoped notifications that require dismissing. In an upcoming VS Code release we will gain the ability to block the rename input box from appearing at a location that does not support a rename.

Preview: Better Handling of Windows Paths

A new setting (dart.previewExperimentalWindowsDriveLetterHandling) has been added. Setting this value to true will cause all drive letters to be converted to uppercase when Dart Code interacts with services like the analysis server. This should fix a number of issues affecting Windows users (unexpected errors like Type 'x' cannot be assigned to type 'x' or completion and errors not updating when referencing code with package:` imports). In future this behaviour may become the default so please try it out and send feedback!

Other Changes
