What it does

Flutter Dependency Injection is an agent skill from HoangNguyen0403/agent-skills-standard. Configure service locator setup using injectable and getit in Flutter. Use when wiring dependency injection with getit or injectable.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/REFERENCE.md` and `references/implementation.md`).

It sits in Mobile, covering Cross-platform mobile apps and Design patterns. It works with Flutter. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Wiring dependency injection with getit
  • Tasks that involve Cross-platform mobile apps
  • Tasks that involve Design patterns

Example prompts

  • “/flutter-dependency-injection”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Annotate classes — Use @injectable annotations; avoid manual registry calls.
  2. Choose scope — Default to @LazySingleton for repositories, services, and data sources (init on demand).
  3. Register BLoCs as factories — Use @injectable (Factory) for BLoCs to ensure state resets per instance. Never use @Singleton() for BLoCs.
  4. Inject abstractions — Always register implementations as abstract interfaces (as: IService).
  5. Register third-party deps — Use @module for external instances (Dio, Hive, SharedPreferences).
  6. Prefer constructor injection — Use mandatory constructor parameters; injectable resolves them automatically.

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter Dependency Injection loads about 589 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~589
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Dependency Injection

Priority: P1 (HIGH)

Structure

text
core/injection/
├── injection.dart  # Initialization & setup
└── modules/        # Third-party dependency modules (Dio, Storage)

Implementation Workflow

  1. Annotate classes — Use @injectable annotations; avoid manual registry calls.
  2. Choose scope — Default to @LazySingleton for repositories, services, and data sources (init on demand).
  3. Register BLoCs as factories — Use @injectable (Factory) for BLoCs to ensure state resets per instance. Never use @Singleton() for BLoCs.
  4. Inject abstractions — Always register implementations as abstract interfaces (as: IService).
  5. Register third-party deps — Use @module for external instances (Dio, Hive, SharedPreferences).
  6. Prefer constructor injection — Use mandatory constructor parameters; injectable resolves them automatically.
Registration & Test Mock Examples

See implementation examples for module registration and test mock swap patterns.

Reference & Examples

For module configuration and initialization templates: See references/REFERENCE.md.

Anti-Patterns

  • No Inline getIt Calls: Inject via constructor instead of calling GetIt in UI build()
  • No @Singleton BLoCs: Always use @injectable (Factory) to ensure state resets
  • No Concrete Class Injection: Always inject abstract interface (e.g., IOrderRepository)
  • No Manual Registration: Use @injectable annotations instead of manual getIt.register calls in production code
