What it does

Flutter Notifications is an agent skill from HoangNguyen0403/agent-skills-standard. Integrate push and local notifications using FCM and flutterlocalnotifications in Flutter. Use for notification delivery or presentation; defer badge-only UI and notification-service tests.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Mobile, covering Cross-platform mobile apps. 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

  • Notification delivery
  • Defer badge-only UI and notification-service tests

Example prompts

  • “/flutter-notifications”

Workflow steps

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

  1. Set up packages — Add firebase_messaging (Push) and flutter_local_notifications (Local/Foreground).
  2. Request permission — Prime users with custom dialog explaining benefits before system prompt.
  3. Handle all lifecycle states — Implement handlers for Foreground, Background, and Terminated states.
  4. Validate payloads — Strictly validate notification data before navigating to screens.
  5. Clear badges — Manually clear iOS app badges when visiting relevant screens.

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 Notifications loads about 418 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 130 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~418
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.

Flutter Notifications

Priority: P1 (HIGH)

Implementation Workflow

  1. Set up packages — Add firebase_messaging (Push) and flutter_local_notifications (Local/Foreground).
  2. Request permission — Prime users with custom dialog explaining benefits before system prompt.
  3. Handle all lifecycle states — Implement handlers for Foreground, Background, and Terminated states.
  4. Validate payloads — Strictly validate notification data before navigating to screens.
  5. Clear badges — Manually clear iOS app badges when visiting relevant screens.
Lifecycle Handlers Example

See implementation examples for foreground, background, and terminated state notification handling.

Implementation Details

Anti-Patterns

  • No Early Permission Popups: Show primer dialog explaining value first
  • No Missing getInitialMessage(): Always handle "open from terminated" startup state
  • No Uncleared Badges: Manually clear notification badges upon related screen visits
  • No Unvalidated Payloads: Validate all JSON data before navigating on click
