Package `cometchat_chat_uikit@6`, which re-exports > `cometchat_sdk@5` (and `cometchat_calls_sdk@5` through the calls barrel). This page is a > **Flutter-v6-only** routing index for AI agents — a scoped alternative to the site-wide > `/docs/llms.txt`. ## How to use this index Each link points to the docs page; **append `.md`** to its URL to fetch the clean Markdown twin (verbatim code + a props table with names, types, and defaults). Pick the page for the intent, then read the props there. * Convention: any docs page URL + `.md` → raw Markdown. * Fallback: if a `.md` twin 404s, fetch the same URL **without** `.md` (HTML). Never read the installed Dart source in place of a doc, and never answer props from memory. ## Platform rules — Flutter is not the web, and v6 is not v5 Widgets render through Flutter's own tree. Non-negotiables: * **TWO barrels, different surfaces.** Chat widgets come from `package:cometchat_chat_uikit/cometchat_chat_uikit.dart`; calling widgets come from `package:cometchat_chat_uikit/cometchat_calls_uikit.dart`. The chat barrel does **not** export the calling widgets and the calls barrel does **not** re-export the chat widgets, so a screen that shows both imports **both**. Importing a calling widget from the chat barrel does not compile — this is the single most common Flutter-specific failure. * **Lists need a bounded box.** `CometChatMessageList`, `CometChatConversations` and the other list widgets fill their parent. Put them in an `Expanded` (or a sized box) inside a `Column`, or layout throws an unbounded-height error at render, not at build. * **Widgets paint their own surface.** The app `ThemeData` does not reach inside a kit widget's background. Scope colours with the widget's own style object — `CometChatMessageListStyle`, `CometChatMessageComposerStyle`, and so on — see [Component Styling](/ui-kit/flutter/component-styling). * **Theming is `ThemeExtension`, not a theme object.** Register `CometChatColorPalette`, `CometChatTypography` and `CometChatSpacing` in `ThemeData.extensions`. Register them on **both** the light and dark themes or one mode silently keeps kit defaults. See [Theming](/ui-kit/flutter/theme-introduction). * **v5's DataSource is gone.** `CometChatUIKit.getDataSource()` no longer exists; v6 exposes `MessageTemplateUtils` instead. Emitting the v5 registration path does not compile — see [MessageTemplateUtils & Data Source](/ui-kit/flutter/customization-datasource) and [Upgrading from v5](/ui-kit/flutter/upgrading-from-v5). * **Custom message types: use `addTemplate`, never `templates`.** `addTemplate:` merges your template with the defaults **and** folds its type/category into the list's fetch and realtime filter. `templates:` replaces the default set and only registers the bubble — a custom type passed there sends successfully and then **never appears**, with no error anywhere. A hand-rolled `MessagesRequestBuilder` does not rescue it either: the list always overrides `uid`, `guid`, `types` and `categories` on the builder you pass. See [Message List](/ui-kit/flutter/message-list) and [Message Template](/ui-kit/flutter/message-template). * **Messages you send yourself must announce themselves.** CometChat does not deliver a client its own sends over the realtime listener, so a message sent with `CometChat.send*Message` rather than through `CometChatMessageComposer` never reaches an already-mounted `CometChatMessageList` — it only appears on that list's next fetch. Emit `CometChatMessageEvents.ccMessageSent(...)` in `onSuccess`. See [Events](/ui-kit/flutter/events). ## Hot path — usually no fetch needed For a plain "add chat" the install, `init → login → render`, and the core drop-in props are stable; a well-built agent skill bakes them. Fetch below only for exhaustive props, long-tail components, theming tokens, or feature enablement. * Setup: [Getting Started](/ui-kit/flutter/getting-started) * Core drop-ins: [Conversations](/ui-kit/flutter/conversations) · [Message Header](/ui-kit/flutter/message-header) · [Message List](/ui-kit/flutter/message-list) · [Message Composer](/ui-kit/flutter/message-composer) ## Getting started / integration * [Getting Started](/ui-kit/flutter/getting-started) * [Flutter UI Kit — Overview](/ui-kit/flutter/overview) * [Components Overview](/ui-kit/flutter/components-overview) * [Core Features](/ui-kit/flutter/core-features) ## Core & configuration * [Methods](/ui-kit/flutter/methods) * [Events](/ui-kit/flutter/events) * [Sound Manager](/ui-kit/flutter/sound-manager) * [Localize](/ui-kit/flutter/localize) * [Extensions](/ui-kit/flutter/extensions) * [Troubleshooting](/ui-kit/flutter/troubleshooting) ## Theming & styling * [Theming](/ui-kit/flutter/theme-introduction) * [Color Resources](/ui-kit/flutter/color-resources) * [Component Styling](/ui-kit/flutter/component-styling) * [Message Bubble Styling](/ui-kit/flutter/message-bubble-styling) ## Components — conversations & lists * [Conversations](/ui-kit/flutter/conversations) * [Users](/ui-kit/flutter/users) * [Groups](/ui-kit/flutter/groups) * [Group Members](/ui-kit/flutter/group-members) * [Search](/ui-kit/flutter/search) ## Components — messages * [Message Header](/ui-kit/flutter/message-header) * [Message List](/ui-kit/flutter/message-list) * [Message Composer](/ui-kit/flutter/message-composer) * [Message Template](/ui-kit/flutter/message-template) * [Threaded Messages Header](/ui-kit/flutter/threaded-messages-header) ## Components — calling Every widget below resolves from the **calls** barrel only (`package:cometchat_chat_uikit/cometchat_calls_uikit.dart`). * [Call Buttons](/ui-kit/flutter/call-buttons) * [Incoming Call](/ui-kit/flutter/incoming-call) * [Outgoing Call](/ui-kit/flutter/outgoing-call) * [Call Logs](/ui-kit/flutter/call-logs) * [Call Features](/ui-kit/flutter/call-features) ## Components — AI & notifications * [Notification Feed](/ui-kit/flutter/notification-feed) * [Campaigns](/ui-kit/flutter/campaigns) ## Customization & extensibility Entries name the **API**, not just the page, because the intent ("add a custom message type") does not match any page title. * **Custom message type** — `CometChatMessageTemplate` + `addTemplate:` (never `templates:`) → [Message Template](/ui-kit/flutter/message-template) · [MessageTemplateUtils & Data Source](/ui-kit/flutter/customization-datasource) * **Custom bubble rendering** — the template's `bubbleView` / `contentView` → [Message Template](/ui-kit/flutter/message-template) * **Replacing a slice of a widget** — per-widget view slots → [View Slots](/ui-kit/flutter/customization-view-slots) * **Loading / empty / error states** — [State Views](/ui-kit/flutter/customization-state-views) * **Long-press menu / composer actions** — [Menu & Options](/ui-kit/flutter/customization-menu-options) * **Driving a widget's data yourself** — [BLoC & Data](/ui-kit/flutter/customization-bloc-data) * **Text formatters** — [Text Formatters](/ui-kit/flutter/customization-text-formatters) * **UI events** — `CometChatUIEvents` → [Events](/ui-kit/flutter/events) * **Kit methods** — [Methods](/ui-kit/flutter/methods) * **Where to start** — [Customization Overview](/ui-kit/flutter/customization-overview) ## Text formatters * [Custom Text Formatter](/ui-kit/flutter/custom-text-formatter-guide) * [Mentions Formatter](/ui-kit/flutter/mentions-formatter-guide) * [Shortcut Formatter](/ui-kit/flutter/shortcut-formatter-guide) ## Task guides (recipes) * [Guides — Overview](/ui-kit/flutter/guide-overview) * [New Chat](/ui-kit/flutter/guide-new-chat) * [Group Chat](/ui-kit/flutter/guide-group-chat) * [Threaded Messages](/ui-kit/flutter/guide-threaded-messages) * [Message Privately](/ui-kit/flutter/guide-message-privately) * [Block / Unblock User](/ui-kit/flutter/guide-block-unblock-user) * [Call Log Details](/ui-kit/flutter/guide-call-log-details) * [Message Agentic Flow](/ui-kit/flutter/guide-message-agentic-flow) ## Framework recipes (full-page layouts) * [Conversation List + Message View](/ui-kit/flutter/flutter-conversation) * [One-to-One / Group Chat](/ui-kit/flutter/flutter-one-to-one-chat) * [Tab-Based Chat](/ui-kit/flutter/flutter-tab-based-chat) * [Multi-Tab Chat UI](/ui-kit/flutter/multi-tab-chat-ui-guide) ## Migration & misc * [Upgrading from v5](/ui-kit/flutter/upgrading-from-v5)
