Dart Modern Features
Skill Verified ActiveGuidelines for using modern Dart features (v3.0 - v3.10) such as Records, Pattern Matching, Switch Expressions, Extension Types, Class Modifiers, Wildcards, Null-Aware Elements, and Dot Shorthands.
To help developers leverage the latest modern Dart features for more concise, readable, and safer code, enabling efficient refactoring and adherence to best practices.
Features
- Guides on Dart Records for aggregate data structures.
- Explains Pattern Matching for data destructuring and validation.
- Demonstrates Switch Expressions for concise value evaluation.
- Covers Class Modifiers for restricted class usage.
- Details Extension Types for zero-cost wrappers.
- Illustrates Digit Separators for number readability.
- Explains Wildcard Variables for unused bindings.
- Shows Null-Aware Elements for conditional collection inclusion.
- Includes Dot Shorthands for type inference.
Use Cases
- Writing or reviewing Dart code targeting Dart 3.0 or later.
- Refactoring legacy Dart code to use modern, concise, and safe features.
- Learning idiomatic ways to handle multiple return values, deep data extraction, or exhaustive checking in Dart.
- Identifying opportunities for code modernization using provided regex patterns.
Non-Goals
- Providing a linter or formatter.
- Automating the refactoring process (it guides manual refactoring).
- Covering Dart language features outside the 3.0 - 3.10 range.

Definition Of Done
100Mandatory checks to run before completing any task that touches md files or dart code in this repository.
Migrate Validate
100Validate pending migrations for foreign key consistency, rollback safety, and best practices
Semgrep Rule Creator
100Creates custom Semgrep rules for detecting security vulnerabilities, bug patterns, and code patterns. Use when writing Semgrep rules or building custom static analysis detections.
Cleanup Cycles
100Detect and untangle circular dependencies. Runs madge/skott (TS), pycycle (Py), or compiler-only checks (Go/Rust). Auto-fixes leaf-extractable cycles; reports core cycles for human review. Use when the user asks to find circular imports, fix dependency cycles, or untangle module graph. Example queries — "find circular imports", "fix dependency cycles", "untangle our module graph", "why is madge complaining".
Coding Standards
100Baseline cross-project coding conventions for naming, readability, immutability, and code-quality review. Use detailed frontend or backend skills for framework-specific patterns.
