What it does

Flutter Layer Based Clean Architecture is an agent skill from HoangNguyen0403/agent-skills-standard. Enforce inward dependency flow, pure domain layers, and DTO-to-entity mapping in Flutter DDD architecture. Use when structuring layers or boundaries; defer navigation-only routing and feature implementation such as notifications.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/REFERENCE.md` and `references/repository-mapping.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

  • Structuring layers
  • Defer navigation-only routing and feature implementation such as notifications

Example prompts

  • “/flutter-layer-based-clean-architecture”

Workflow steps

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

  1. Define domain entity with @freezed in lib/domain/entities/
  2. Define repository interface in lib/domain/repositories/
  3. Create DTO in lib/infrastructure/dtos/ with fromJson/toEntity mapper
  4. Implement repository in lib/infrastructure/repositories/
  5. Wire BLoC/Cubit in lib/application/ consuming repository interface
  6. Register bindings in get_it injection container
  7. Build screen in lib/presentation/ using BlocBuilder

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 Layer Based Clean Architecture loads about 695 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~695
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

Enforce inward dependency flow, pure domain layers, and DTO-to-entity mapping in Flutter DDD architecture. Use when structuring layers or boundaries; defer navigation-only routing and feature implementation such as notifications.

Layer-Based Clean Architecture

Priority: P0 (CRITICAL)

Workflow: Add New Feature Across Layers

  1. Define domain entity with @freezed in lib/domain/entities/
  2. Define repository interface in lib/domain/repositories/
  3. Create DTO in lib/infrastructure/dtos/ with fromJson/toEntity mapper
  4. Implement repository in lib/infrastructure/repositories/
  5. Wire BLoC/Cubit in lib/application/ consuming repository interface
  6. Register bindings in get_it injection container
  7. Build screen in lib/presentation/ using BlocBuilder

Structure

text
lib/
├── domain/ # Pure Dart: entities (@freezed), failures, repository interfaces
├── infrastructure/ # Implementation: DTOs, data sources, mappers, repo impls
├── application/ # Orchestration: BLoCs / Cubits
└── presentation/ # UI: Screens, reusable components

Implementation Guidelines

  • Dependency Flow: Presentation -> Application -> Domain <- Infrastructure. Dependencies point inward.
  • Pure Domain: No Flutter (Material/Store) or Infrastructure (Dio/Hive) dependencies in Domain.
  • Functional Error Handling: Repositories must return Either<Failure, Success>.
  • Always Map: Infrastructure must map DTOs to Domain Entities; not leak DTOs to UI.

See DTO-to-Entity mapping example.

  • Immutability: Use @freezed for all entities and failures.
  • Logic Placement: No business logic in UI; widgets only display state and emit events.
  • Inversion of Control: Use get_it to inject repository implementations into BLoCs.

Anti-Patterns

  • No DTOs in UI: Never import .g.dart or Data class directly in Widget.
  • No Material in Domain: not import package:flutter/material.dart in domain layer.
  • No Shared Prefs in Repo: not use shared_preferences directly in Repository; use Data Source.
