Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Implementing Dart Patterns ## Contents - [Pattern Selection Strategy](#pattern-selection-strategy) - [Switch Statements vs. Expressions](#switch-statements-vs-expressions) - [Core Pattern Implementations](#core-pattern-implementations) - [Pragmatic Balance & Anti-Patterns](#pragmatic-balance--anti-patterns) - [Workflows](#workflows) - [Examples](#examples) ## Pattern Selection Strategy Apply specific pattern types based on the data structure and desired outcome. Follow these conditional guidelines: * **If validating and extracting from deserialized data (e.g., JSON):** Use Map, List, and Object patterns to validate schema structure and destructure properties in a single step. * **If inspecting URL/path segments (`uri.pathSegments`, `p.split(path)`) or `String.split()` tokens:** Use List patterns with rest elements (`['api', 'comments', ...]`, `['assets', ...final rest]`, `[..., final parent, _]`) instead of manual `.length` checks, `.first`, `.skip(1)`, or `length - N` index arithmetic. * **If handling polymorphic payloads or responses:** Use `switch` expressions over map discriminant keys to deserialize into `sealed` class hierarchies. …

How to install
mdr add sutchan/agent-skills-hub/dart-use-pattern-matching@sha256:c880640f2a95caa2The line at the top of this page pins the label git:20261017.b913806, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
