Cometchat Flutter V6 Events

What it does

When your agent uses it

• Tasks that involve Cross-platform mobile apps
• Tasks that involve Design systems

Example prompts

• “listen for new messages”
• “react when a message is sent”
• “cometchat listener flutter”
• “/cometchat-flutter-v6-events”

Requirements

• Compatibility (from SKILL.md): Flutter >=3.38.9; cometchat_chat_uikit ^6 (6.1.x, verified 6.1.0); cometchat_sdk ^5.0.6

Workflow steps

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

1. 1Register in initState, remove in dispose — always paired.
2. 2A unique, stable listener id per screen. Reusing one id across screens means the later registration silently replaces the earlier.
3. 3Removing matters more than you think in Flutter: hot restart and route re-entry both re-run initState. A listener you never removed fires…
4. 4Register AFTER login. A listener added before login resolves receives nothing.

What it can do on your machine

Read from SKILL.md and the folder at commit 911b108. 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 (its code samples are dart).

  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.

• Compatibility

  Flutter >=3.38.9; cometchat_chat_uikit ^6 (6.1.x, verified 6.1.0); cometchat_sdk ^5.0.6

  From compatibility in the SKILL.md frontmatter.

Context cost

Cometchat Flutter V6 Events loads about 1.5k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 507 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~113

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

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

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.

description

React to CometChat activity in a Flutter app — SDK listeners (messages, calls, users, groups, connection) versus UI Kit events (CometChatMessageEvents, CometChatGroupEvents, CometChatUserEvents, CometChatConversationEvents), and the listener lifecycle that keeps them from leaking. Triggers: 'listen for new messages', 'react when a message is sent', 'cometchat listener flutter', 'unread badge count', 'onMessageReceived'.
