Flutter Integration Testing
#3009/#3133: Flutter tests inside an integration_test folder are now recognised as tests and run on the selected device. See flutter.dev/docs/testing/integration-tests for more information on using the Flutter SDK’s package:integration_test.

New Refactors
#547/#545: New refactors have been added for Inline Method and Inline Local Variable (requires SDK update).

Editor
Items here marked “(requires SDK update)” also rely on changes in the Dart/Flutter SDKs so may not be immediately visible depending on your Dart/Flutter SDK channel.
- #3303: When using LSP and the 
completeFunctionCalls setting, code completion will no longer insert additional parenthesis/argument placeholders when they already exist in the document (requires SDK update). - #3289: Brackets around references in dartdoc comments are no longer colored inconsistently when using LSP with Semantic Tokens (requires SDK update).
 - #3281: Code completion no longer incorrectly returns results when invoked in a comment right at the end of a file.
 - #3253/#3250: Renaming files that do not need to update any 
import statements will no longer trigger the VS Code refactor prompt (requires SDK update for LSP, not for non-LSP). - #3227: Code completion no longer shows duplicate classes when multple libraries are imported that re-export the same symbols (requires SDK update).
 - #3225: Code folding now works for Enum bodies (requires SDK update).
 - #3211: Code completion now intelligently triggers automatically for LSP when typing imports/slashes/interpolation(requires SDK update).
 - #3248: A new setting 
dart.automaticCommentSlashes has been added to control the new automatic comment marker behaviour added in the previous release. - #3174: Code completion now includes 
? in the display of nullable types in signatures and descriptions. 
Flutter
- #3302: Custom emulators (using 
flutterCustomEmulators) now show error messages if they fail to launch. - #3267: Custom emulators (using 
flutterCustomEmulators) can now define additional environment variables using the env key. - #3258: Automatic Flutter initialization now works even if you have no other Dart SDKs on 
PATH. - #3246: When using embedded DevTools, 
dart.openDevTools will now open the embedded Inspector page for Flutter apps instead of opening a separate browser. For non-Flutter apps, DevTools will still be launched in a browser. 
Debugger
- #3294: Custom CodeLens templates can now use exact file paths in their 
path filter instead of only folders. 
Commands
- #3275: Embedded DevTools is now disabled for IDEs like Theia that do not support iframed webviews.
 - #3274: Embedded DevTools are now supported for Remote VS Code sessions where the necessary ports can be forwarded.
 - #3261: VS Code shortcut keys (like the command palette) now work even when embedded DevTools has focus (requires DevTools update).
 
Other
- #3301: The experimental 
flutterDisableVmServiceExperimental setting has been removed. - #2853/#3292: Snap support has been simplified and should now work more reliably if you have never run 
flutter since installing the Snap package. - #3257: The New Project commands now spawn in the current window instead of opening new windows.
 - #3256: LSP will no longer be enabled by default for editor versions that do not meet the minimum required version for the LSP client.
 - #3183: Settings that are considered experimental (and may have significant issues) are now more clearly marked in their descriptions.
 - #3300: Enum settings now have improved descriptions for their values when using the VS Code settings UI.
