🤖 SKILL INSTRUCTIONS: DART ANALYZE

🎯 AGENT BEHAVIOR (HOW TO EXECUTE)

When the user asks you to analyze or fix code:

1. Analyze: Run dart analyze 2>&1 in the terminal to identify all errors, warnings, and infos.
2. Prioritize: Group the issues by severity (Error > Warning > Info).
3. Resolve: Apply fixes systematically starting with CRITICAL errors.
4. Verify: Re-run dart analyze until 0 issues are found.
5. Test: Run flutter test to ensure your fixes did not break existing logic.

🛑 1. STRICT CORE PRINCIPLES

• ZERO TOLERANCE: Delivered code MUST be completely free of errors, warnings, and infos.
• NO IGNORING: You are FORBIDDEN from adding // ignore: or // ignore_for_file: comments unless there is absolutely no other technical solution, and you MUST add a clear comment explaining why.
• NO CONFIG TAMPERING: You MUST NOT modify analysis_options.yaml to hide or silence issues.

🛠️ 2. EXECUTION COMMANDS

Use these commands to perform your tasks:

# Full project analysis
dart analyze
 
# Strict analysis (fails even with infos)
dart analyze --fatal-infos
 
# Auto-apply safe fixes before manual review
dart fix --apply

🚨 3. RESOLUTION RULES BY CATEGORY

3.1. Errors (CRITICAL)

MUST be resolved immediately. NEVER ignore.

• missing_required_param: Add the required parameter.
• missing_return: Add the missing return statement or change the return type.
• parameter_assignments: Do NOT reassign parameters; create a local final variable.
• unawaited_futures: Add await or wrap in unawaited().

3.2. Warnings

MUST be resolved before task completion.

• deprecated_member_use: Migrate to the recommended API immediately.
• unused_import: Remove the import.
• avoid_print: Replace print with debugPrint or the project's custom logger.
• prefer_const_constructors / prefer_const_literals_to_create_immutables: Add const.
• prefer_final_locals: Change var to final.
• annotate_overrides: Add the @override annotation.

3.3. Infos (Linter Rules)

• prefer_single_quotes: Change "..." to '...'.
• prefer_relative_imports: Use relative imports for files within lib/.
• unnecessary_string_interpolations: Replace '$var' with var when no other text is present.
• cascade_invocations: Use .. when invoking multiple methods on the same object.

📊 4. CODE METRICS RULES (dart_code_linter)

If the project uses custom metrics, you MUST refactor the code if it exceeds these limits:

✅ 5. PRE-OUTPUT CHECKLIST

Before completing your response, ensure internally:

• [ ] Does dart analyze return 0 issues?
• [ ] Does flutter test still pass successfully?
• [ ] Did I avoid adding unjustified // ignore: comments?
