Language Version vs. SDK Version\n- **Language Version (`major.minor`)**: In `pubspec.yaml`, the lower bound of `environment.sdk` (for example `^3.13.0` or `>=3.12.0 <4.0.0`) dictates which language grammar and compiler semantics are enabled.\n  - Patch numbers (`.1`, `.2`) do **not** affect language grammar.\n  - Using a Dart 3.13 feature (like Primary Constructors) requires `sdk: '^3.13.0'`.\n- **Core Library APIs**: Methods and classes (for example `Future.pause`, `List.unmodifiableOf`) are added in specific SDK versions.\n- **Per-file override**: A file can specify `// @dart = 3.12` on line 1 to force an earlier language version.\n\n### 2.

Working with Augmentations & Macros\n1. Review [Macros & Augmentations Guide](references/macros-and-augmentations-guide.md).\n2. Wire original files with `import augment 'foo.g.dart';` and augmentation files with `augment library 'foo.dart';`.\n3. Use `augment class`, `augment void method()`, and call `augmented()` to wrap original logic.\n\n### 2. Working with Experimental Feature Flags\n1. Check if the feature has already graduated to stable in the active SDK before adding a flag.\n2. If experimental, configure `analysis_options.yaml` under `analyzer.enable-experiment: [name]`.\n3. Pass `--enable-experiment=name` to `dart run`, `dart test`, `flutter run`, and `flutter test`.\n4. Ensure experimental code is isolated so production packages remain publishable on pub.dev.\n\n### 3. Modernizing / Rescuing a Legacy Codebase\n1. Check current language version from `pubspec.yaml` environment block.\n2. If pre-2.12, read the [Legacy Rescue Guide](references/rescuing-legacy-dart-apps.md).\n3. Execute the 4-stage pipeline: syntax cleanup &rarr; sound null safety &rarr; dependency bump (`sdk: ^3.5.0` or `^3.13.0`) &rarr; Dart 3 modernization.\n\n### 4. Answering \"What's New in Dart X.Y\"\n1. Identify the requested version.\n2. Read the corresponding reference document under `references/`.\n3. Provide:\n   - **Language syntax changes** with before/after code snippets.\n   - **Core library additions** (`dart:core`, `dart:async`, `dart:io`, `dart:js_interop`, `dart:isolate`, `dart:ffi`).\n   - **Tooling and CLI features** (`dart analyze`, `dart format`, `dart pub`, `dart build`).\n   - **Breaking changes and migration instructions**.\n\n### 5.
