What it does

Cometchat Flutter V6 Customization is an agent skill from cometchat/cometchat-skills. Theme and brand the Flutter v6 UI Kit — light/dark mode, the CometChatColorPalette / CometChatTypography / CometChatSpacing theme extensions, per-widget style objects, and view slots. Triggers: 'change chat colors flutter', 'dark mode chat flutter', 'match my brand flutter', 'customize cometchat theme flutter', 'override message bubble styles'.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Flutter =3.38.9; cometchatchatuikit ^6 (6.1.x, verified 6.1.0)

It sits in Mobile, covering Cross-platform mobile apps, Theming and dark mode and Design systems. It works with CometChat and Flutter. The repository describes itself as: Add CometChat chat & messaging and voice & video calls to any React, Next.js, React Native, Angular, Android, iOS, or Flutter project through your AI coding agent. Works with… The licence is MIT.

When your agent uses it

  • Tasks that involve Cross-platform mobile apps
  • Tasks that involve Theming and dark mode
  • Tasks that involve Design systems

Example prompts

  • “change chat colors flutter”
  • “dark mode chat flutter”
  • “match my brand flutter”
  • “/cometchat-flutter-v6-customization”

Requirements

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

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)

    From compatibility in the SKILL.md frontmatter.

Context cost

Cometchat Flutter V6 Customization loads about 1.8k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 575 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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.

cometchat flutter customization theming theme-extension styles v6

Ground truth: theming is Flutter's own ThemeExtension mechanism — CometChatColorPalette, CometChatTypography, CometChatSpacing, all catalog-verified against 6.1.0. The exhaustive token list is FETCHED from the docs (theme-introduction · color-resources · component-styling · message-bubble-styling via ../cometchat-flutter-v6-core/references/docs-map.md) — do NOT bake it.

Companion skills (read first)

  • cometchat-flutter-v6-core — install, credentials, init→login→render. This skill ASSUMES it.
  • cometchat-flutter-v6-components — the widget catalog whose style objects and slots this skill sets.

Use this skill when

Branding or theming: colors, fonts, light/dark, or per-widget style overrides.

Prerequisites & install

Covered by core. No new package.

Customization mechanism (BAKED — v6)

Three tiers, in the order you should reach for them:

1. App-wide theme — ThemeExtension on your ThemeData. This is the main lever; it restyles every CometChat widget at once.

dart
import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';

final cometchatLight = ThemeData(
  fontFamily: 'Inter',
  extensions: [
    CometChatColorPalette(primary: const Color(0xFFF76808)),
    CometChatTypography(),
    CometChatSpacing(),
  ],
);

2. Light / dark — Flutter's own switching, nothing CometChat-specific. Supply both themes and let themeMode decide; ThemeMode.system follows the OS, which is the right default for a fresh app.

dart
import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';

Widget app(Widget home) => MaterialApp(
      theme: ThemeData(extensions: [CometChatColorPalette(primary: const Color(0xFFF76808))]),
      darkTheme: ThemeData.dark().copyWith(
        extensions: [CometChatColorPalette(primary: const Color(0xFFF76808))],
      ),
      themeMode: ThemeMode.system,   // follow the device setting
      home: home,
    );

Unlike the web kit (a theme prop + CSS variables), Flutter has no CometChat-specific mode switch — do not invent one. Register the palette on BOTH themes or dark mode falls back to defaults.

3. Per-widget style objects — scope one surface only. Every widget takes a *Style object: CometChatConversationsStyle · CometChatMessageHeaderStyle · CometChatMessageListStyle · CometChatMessageComposerStyle · CometChatThreadedHeaderStyle · CometChatSearchStyle · CometChatIncomingMessageBubbleStyle / CometChatOutgoingMessageBubbleStyle · CometChatCallLogsStyle.

dart
import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';

Widget themedHeader(User user) => CometChatMessageHeader(
      user: user,
      messageHeaderStyle: const CometChatMessageHeaderStyle(
        backgroundColor: Color(0xFFFFFFFF),
        titleTextColor: Color(0xFF141414),
        subtitleTextColor: Color(0xFF727272),
        onlineStatusColor: Color(0xFF09C26F),
      ),
    );

Style parameter names are per-widget and NOT guessable — the header uses titleTextColor/onlineStatusColor, the threaded header uses bubbleContainerBackGroundColor/countTextColor, search uses searchBackgroundColor/searchBorderRadius. Fetch the widget's .md twin before writing a style block. Message bubbles are themed app-wide through CometChatIncomingMessageBubbleStyle / CometChatOutgoingMessageBubbleStyle registered as theme extensions — see message-bubble-styling.

Reading theme values in your own widgets

CometChatThemeHelper.getColorPalette(context) (and the typography/spacing equivalents) returns the resolved palette, so custom UI in a slot matches the kit instead of hard-coding hexes.

Beyond colour — the other customization axes (FETCH the page)

  • View slots — replace any row/section (customization-view-slots); custom UI goes IN the slot.
  • State views — loadingStateView / emptyStateView / errorStateView (customization-state-views).
  • Menu options — add or remove message actions via CometChatMessageOption and the template's options (customization-menu-options). The callback is onItemClick(message, state).
  • Text formatters — CometChatMentionsFormatter and custom CometChatTextFormatter subclasses (customization-text-formatters, custom-text-formatter-guide). A subclass must implement init, getMessageInputTextStyle, handlePreMessageSend, onChange and onScrollToBottom — the class is abstract.
  • Message templates — custom message types and bubbles (message-template, → -components).
  • Sounds — the class is SoundManager, UN-prefixed (there is no CometChatSoundManager), a singleton: SoundManager().play(sound: Sound.incomingMessage, customSound: "assets/ping.mp3") / .stop(). Compiler-verified vs 6.1.0. It is absent from the catalog only because that tracks CometChat* symbols — same as User/Group. Page: sound-manager.
  • Localization — via CometChatLocalize, the same localization class the other families use: register its delegate in MaterialApp.localizationsDelegates and read/override strings through it. Fetch the exact Flutter API from the live localize page (references/docs-map.md → Localization). [STAGED — needs the UI Kit change] CometChatLocalize requires a cometchat_chat_uikit version that exposes it; the pinned 6.1.0 does not (it exposes Translations). Bump the pin + refresh catalogs/flutter-v6.json when that kit ships — until then Flutter localization emitted this way will not compile.

Common pitfalls (BAKED)

  • Inventing a CometChat dark-mode switch. Use ThemeData + themeMode; register the palette on both themes.
  • Guessing style parameter names. They differ per widget — fetch the twin.
  • Hard-coding colours in a custom slot instead of reading CometChatThemeHelper.
  • v5 theming APIs — CometChatTheme is now only a mergeThemeExtensions helper, not a palette holder; the v5 CometChatThemeData/DataSource styling path is gone (→ -migration).
  • Restyling by wrapping the widget rather than passing its style object or slot.

Verify it works

The brand colour appears on the surfaces you expect, light and dark both render (toggle the OS setting), custom slot UI matches the kit's palette, and no widget silently kept its default because the palette was registered on only one theme.
