Dart-Code

Dart Code can be installed from the Visual Studio Code Marketplace. Open VS Code Quick Open (Ctrl+P) and paste the following and press enter:

Changes

• Dart Code will now activate if a workspace contains a .dart file rather than only if it contains a pubspec.yaml file or when a .dart file is specifically opened

• Errors that occur when running Flutter debug commands will now be shown in the debug console
• The Closing Labels preview has been updated to use functionality provided by the Dart SDK which will result in better performance and improved labels (this requires SDK v1.25.0-dev.11.0 or later)

Preview Features available in this version

• dart.previewClosingLabels - Show annotations against constructor, method invocations and lists that span multiple lines
• dart.previewAnalyzeAngularTemplates - Enables analysis for AngularDart templates (requires the angular_analyzer_plugin)

Flutter Debugging Commands

Several new commands have been added to aid Flutter debugging. These appear in the command palette but can be bound to keys in the Keyboard Shortcuts window in Code.

• Toggle Debug Painting
• Toggle Performance Overlay
• Toggle Slow Animations
• Toggle Repaint Rainbow
• Toggle Platform (Android/iOS)
• Toggle Baseline Painting
• Toggle Slow-Mode Banner

Additionally the default hotkey for Organize Directives has been removed to avoid a warning from Code about modifier keys. You can rebind this command in Code's Keyboard Shortcuts window.

Flutter Support

v2.0 is a major update that adds significant flutter support, including debugging and hot reload!

Changes

Note: If you previously installed a beta version of Dart Code to help with testing Flutter integration, please uninstall it and close all Code instances before installing v2.0 from the marketplace.

• [Flutter] When opening a Flutter project your selected device will be shown in the status bar
• [Flutter] If you have more than one connected device you will be able to switch between them by clicking on the device in the status bar
• [Flutter] Pressing F5 will build and launch your app on the selected device
• [Flutter] The usual debugging experience is available for Flutter apps, including breakpoints, call stacks, watch window etc.
• [Flutter] The debugger's Restart button (or Ctrl+Shift+F5) has been mapped to Flutter's hot reload and will update the running application without needing to rebuild
• [Flutter] Code completion for Widgets will no longer show trailing commas in the list (though they will still be inserted)
• Clicking the debugger's restart button for a Dart CLI app will no longer crash but instead provide a more useful message about being unable to restart when VS Code does not supply toe correct configuration (this issue is fixed for VS Code 1.14 coming soon)
• Stack frame text when stopped in the debugger is now improved and will show async gaps
• Cursor placement after code fixes and assists should now be more accurate

The contributing file has also been updated to make it easier to get started with contributing to Dart Code.

Dart Code can be installed from the Visual Studio Code Marketplace. Open VS Code Quick Open (Ctrl+P) and paste the following and press enter:

ext install dart-code

Note: This version requires Visual Studio Code 1.13.

Changes

• Argument placeholders will now (again) insert placeholder text instead of empty strings
• Completing methods that take no arguments will no longer place the cursor between the parens as if there are arguments to type
• When selecting items from the code completion list the cursor will now more reliably move to the expected location after insertion
• New snippets have been added for test and group methods defined in the test package
• Dart Code will now activate when opening workspaces that include a pubspec.yaml anywhere in the tree, not just in the workspace root folder
• Debug logging will no longer appear in the Debug Output window when launching a debug session
• Snippets now have slightly more verbose descriptions of their functionality

This is a beta release from the Flutter branch. Please test and report general feedback at #318 or raise issues for problems. If you don't have issues, please still post in #318 and include which platform you're using to help gauge stability!

• When opening a flutter project, the .packages file will now also be used when trying to locate the Flutter SDK
• The error message shown when unable to locate the Flutter SDK has been simplified and a link to the Flutter download page added
• The environment variable FLUTTER_HOME is not recommended for use and will no longer be used to locate a Flutter SDK (FLUTTER_ROOT is still checked)

Dart Code can be installed from the Visual Studio Code Marketplace. Open VS Code Quick Open (Ctrl+P) and paste the following and press enter:

ext install dart-code

Changes

• When opening a Flutter project, the below locations will be checked for a Flutter SDK and the embedded Dart SDK will be used (if no flutter SDK is found an error message will be shown)

  • (FLUTTER_ROOT)\bin\flutter(.bat)
  • (FLUTTER_HOME)\bin\flutter(.bat)
  • All folders in PATH

Dart Code can be installed from the Visual Studio Code Marketplace. Open VS Code Quick Open (Ctrl+P) and paste the following and press enter:

ext install dart-code

Changes

• The change made in v1.1.0 to support opening the Flutter repo introduced some new issues and has been reverted except for specific workspaces. The issue is caused by using a folder named packages which is not currently supported by the analyzer. In order to fix the issue for the Flutter repo the workaround will be triggered by the presence of a .\packages\.gitignore file (which exists in the Flutter repo but not in packages folders created by pub). This workaround will be removed once the Analyzer has been updated.

• Setting Dart SDK/libraries as debuggable/non-debuggable will now work correctly with SDK 1.23 which has different debugging defaults
• The launch.json file should now be much simpler than before and not contain internal Dart Code settings that are not relevant to the user *
• The launch.json file now properly supports default so checkedMode: true and args: [] are not longer required unless being changed *

* Your launch.json file should automatically be tidied up when you first open your project.
