Features Enabled with Future SDKs

These items rely on changes to the Dart/Flutter SDKs that have not yet been released to stable channels. They will show up automatically when you update your SDK in future (or if using development channels depending on the exact version).

Upstream Issues

Some feature requests and fixes require new features and fixes in upstream projects like VS Code and LSP which use counts of 👍s on those issues to help gauge demand. The Dart-Code website now lists some of the most significant upstream issues with a description of the feature/fix they would enable. Please consider reviewing this list and adding your 👍 to any GitHub issues relevant to features you’d like to see!
