| description | Standards for code quality, linting, and modern API usage in Flutter. Use when writing or modifying Dart code. Covers deprecations and analyzer rules. |
After making substantive changes to Dart code, ALWAYS run flutter analyze to catch errors, warnings, and deprecations.
Flutter evolves rapidly. You must be aware of and prefer modern language features and APIs over outdated ones, even if the analyzer doesn't strictly forbid the old ones yet.
Common Deprecations to Watch:
.withValues(alpha: ...) over .withOpacity(...)..toARGB32() over .value for Colors.activeThumbColor over activeColor in Switches.LLMs often default to older patterns found in their training data.
WillPopScope, Opacity, etc.) has a newer replacement (like PopScope, withValues).flutter analyze flags a deprecation, treat it as an error to be fixed immediately.Efficient app-driving workflow for the real Flutter app on emulator or Linux/macOS desktop via VM service extensions, including common blocker recovery.
Quality gate protocol between implementation and handoff.
Guidelines for creating and maintaining documentation in the Nothingness project. Use when adding architecture docs, design docs, or complex logic explanations.
Guidelines for running Flutter CLI commands and handling sandbox permissions. Use when executing flutter build, run, pub, or clean commands.
Guidelines for polling GitHub Actions workflow runs via MCP tools. Use when working with CI/CD workflows, monitoring builds, or debugging workflow failures.
