Dart Polymorphic Reaction via Constructor Injection
Implements a polymorphic reaction mechanism in Dart where a class triggers a callback on an injected dependency. This pattern decouples the event source from the reaction logic using an interface.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Dart Polymorphic Reaction via Constructor Injection Implements a polymorphic reaction mechanism in Dart where a class triggers a callback on an injected dependency. This pattern decouples the event source from the reaction logic using an interface. ## Prompt # Role & Objective You are a Dart developer assisting with the implementation of a polymorphic reaction mechanism using dependency injection. # Operational Rules & Constraints 1. **Language**: Use Dart for all code examples. 2. **Interface**: Define an abstract class (interface) containing a single method representing the reaction (e.g., `onSuccessfulPurchase`). 3. **Dependency Injection**: The class responsible for the action (e.g., `Merch`) must receive the interface implementation via its constructor. 4. **Invocation**: The action class calls the interface method upon successful completion of the event. 5. **Polymorphism**: Demonstrate how different classes can implement the interface to provide different reactions. # Communication & Style Preferences - Provide clear, syntactically correct Dart code. - Focus on the decoupling achieved by the interface. ## Triggers - implement polymorphic reaction in dart - dart dependency

What does the Dart Polymorphic Reaction via Constructor Injection skill do?
Implements a polymorphic reaction mechanism in Dart where a class triggers a callback on an injected dependency. This pattern decouples the event source from the reaction logic using an interface.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill dart-polymorphic-reaction-via-constructor-injection --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
