get_it Expert

What it does

Provides an expert reference for using get_it as a service locator in Flutter/Dart apps. The skill explains registration types (singleton, lazy, factory, async), scope mechanics (push/pop, shadowing), recommended async initialization patterns (init() + registerSingletonAsync), retrieval APIs, testing patterns that use scoped mocking, and production anti-patterns. It includes code examples for common tasks and patterns developers will run into when wiring DI in real apps.

When to use it

Use this skill while architecting or refactoring dependency registration in a Flutter app, when implementing async service initialization, when adding per-user scopes (session management), or when writing tests that need to shadow real services. It's especially helpful during app startup, testing setup/teardown, and debugging service lifecycle issues.

What's included

• Scripts: none in the repo's skill folder (has_scripts=false)
• References: none in the skill folder (has_references=false)
• Instructions: Clear, copyable code snippets showing registerSingleton, registerLazySingleton, registerFactoryParam, registerSingletonAsync with dependsOn ordering, scope push/pop (sync vs async), allReady/isReady usage, retrieval patterns (get, maybeGet, getAsync), and recommended async init pattern that returns this.

Compatible agents

Inferred: developer-focused agents that can provide code examples and refactors (Copilot/Codex-style assistants, Claude Code, GPT-based coding assistants).
