cometchat-flutter-v6-components

Ground truth: catalogs/flutter-v6.json — 296 symbols, compiler-verified against the published 6.1.0, with symbolsByBarrel recording which barrel each resolves from. The lists below are that catalog, grouped. If a name is not in the catalog it does not exist — do not emit it. Props come from the docs .md twin (../cometchat-flutter-v6-core/references/docs-map.md), never from memory.

Companion skills (read first)

• cometchat-flutter-v6-core — install, credentials, init→login→render, the two barrels. This skill ASSUMES it and does not repeat it.

Use this skill when

Choosing, composing, or swapping UI Kit widgets; "which widgets exist"; customizing a list, message, or bubble.

Prerequisites & install

Covered by core. This skill adds no package.

Widget catalog (BAKED closed list — from the catalog)

Lists & screens: CometChatConversations · CometChatUsers · CometChatGroups · CometChatGroupMembers · CometChatSearch · CometChatNotificationFeed Messages: CometChatMessageHeader · CometChatMessageList · CometChatMessageComposer · CometChatThreadedHeader · CometChatMessageInformation · CometChatMessagePreview · CometChatReactions · CometChatReactionList · CometChatMediaRecorder · CometChatEmojiKeyboard · CometChatStickerKeyboard Bubbles: CometChatTextBubble · CometChatImageBubble · CometChatVideoBubble · CometChatAudioBubble · CometChatFileBubble · CometChatVoiceNoteBubble · CometChatDeletedBubble · CometChatActionBubble · CometChatMessageBubble · CometChatLinkPreviewBubble · CometChatPollsBubble · CometChatStickerBubble · CometChatCollaborativeBubble · CometChatStreamBubble · CometChatAIAssistantBubble · CometChatCallBubble Groups: CometChatChangeScope · CometChatCreatePoll AI: CometChatAISmartRepliesView · CometChatAIConversationStarterView · CometChatAIConversationSummaryView · CometChatAIAssistantChatHistory · CometChatAIAssistantEvents Theme primitives: CometChatColorPalette · CometChatTypography · CometChatSpacing · CometChatThemeHelper (→ -customization)

CometChatMediaRecorder and CometChatEmojiKeyboard are REAL in Flutter v6 even though they are phantoms in the React pack. Never carry another family's phantom list here — check catalogs/flutter-v6.json. Plural/singular matters: CometChatPollsBubble (not PollBubble), CometChatThreadedHeader (not ThreadHeader). CometChatImagesBubble/CometChatAudiosBubble/CometChatFilesBubble/CometChatVideosBubble also exist as the multi-attachment variants — the singular forms are the standard bubbles. Exception: CometChatAudioBubble is a deprecated typedef alias for CometChatVoiceNoteBubble (audio_bubble/cometchat_voice_note_bubble.dart) — use CometChatVoiceNoteBubble (single voice note) or CometChatAudiosBubble (multi-attachment) instead; it compiles today but rides a deprecated symbol (AUDIT-233). The message-translation bubble is UN-prefixed (MessageTranslationBubble); only its style class carries the prefix.

Calls widgets live in the OTHER barrel (compile trap)

CometChatIncomingCall · CometChatOutgoingCall · CometChatOngoingCall · CometChatCallButtons · CometChatCallLogs · CometChatCallBubble · CometChatCalls resolve only from:

import 'package:cometchat_chat_uikit/cometchat_calls_uikit.dart';

That barrel does not re-export the chat widgets, so a calls screen imports both. Detail: cometchat-flutter-v6-calls.

Swap / compose slots

• Custom UI goes IN a widget's slot, never stacked beside it. Every list widget exposes listItemView (replace the whole row) plus finer slots — leadingStateView · titleView · subtitleView · trailingView — and state slots loadingStateView / emptyStateView / errorStateView.
• Check the parameter ORDER before writing a slot. v6 slots are not uniform: CometChatConversations.leadingView is (context, conversation), while CometChatMessageHeader.subtitleView is (group, user, context). Fetch the widget's .md twin rather than assuming.
• Prefer configuring the highest-level widget over rebuilding it from bubbles.
• Reuse built-in callbacks before adding your own control — onItemTap · onItemLongPress · onSelection · onBack · onError · onLoad. Note the arity differs by widget: CometChatUsers/CometChatGroups take onItemTap: (context, item), while CometChatConversations/CometChatGroupMembers take onItemTap: (item).
• Scope data with the request builder, not a client-side filter: conversationsRequestBuilder · usersRequestBuilder · groupsRequestBuilder · groupMembersRequestBuilder.

Swapping a bubble (message templates)

There is no per-bubble prop on the list — a custom bubble is a CometChatMessageTemplate whose bubbleView you override. Defaults come from MessageTemplateUtils (v6 replaced the v5 DataSource; CometChatUIKit.getDataSource() is gone).

Which prop you pass it to is NOT interchangeable (message-list § Message Templates; customization-view-slots; customization-datasource):

• addTemplate: — merges with the defaults. This is the one for a message type of your own.
• templates: — replaces the whole default set.

Reach for addTemplate: for anything the kit does not already ship, and templates: only when you deliberately want to drop the defaults. Templates are keyed category_type, so an addTemplate: entry matching an existing key overrides just that bubble (customization-datasource).

Do not try to widen the list's fetch with your own builder: message-list states that uid, guid, types and categories on a MessagesRequestBuilder are always overridden inside the message list.

Overriding a type the kit already ships (templates:):

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

final textTemplate = CometChatMessageTemplate(
  type: CometChatMessageType.text,
  category: CometChatMessageCategory.message,
  bubbleView: (message, context, alignment) =>
      message is TextMessage ? Text(message.text) : const SizedBox.shrink(),
);

Adding a type of your own (addTemplate:):

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

final diceRollTemplate = CometChatMessageTemplate(
  type: 'game_roll',                              // your own type string
  category: CometChatMessageCategory.custom,      // CustomMessage is always `custom`
  bubbleView: (message, context, alignment) => Text(
      message is CustomMessage ? '${message.customData?['value']}' : ''),
);

Widget gameChat(Group group) => CometChatMessageList(
      group: group,
      addTemplate: [diceRollTemplate],   // `templates:` here would render nothing
    );

Creating a group (host-composed — no kit widget)

v6 ships no create-group widget; build the form yourself and create with the SDK. It MUST offer all three types — Public · Private · Password-protected — with the password field required for the third.

import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';

Future<void> createGroup(String guid, String name, String? password) async {
  final group = Group(
      guid: guid, name: name, type: CometChatGroupType.password, password: password);
  // NOTE: `group:` is a NAMED parameter, and onSuccess/onError are both required.
  await CometChat.createGroup(group: group, onSuccess: (g) {}, onError: (e) {});
}

Common pitfalls (BAKED)

• Emitting a widget that isn't in the catalog — the #1 hallucination. Check first.
• Importing a calls widget from the chat barrel — does not compile (see above).
• Assuming a slot's parameter order or arity — v6 is inconsistent between widgets; fetch the twin.
• Stacking custom UI beside a widget instead of passing it into the slot.
• Emitting a widget below its contracts.flutter-v6.json minimum — a group-details screen needs view/kick/ban/scope, not just a member list.
• Hand-rolling moderation or report UI — both are automatic in CometChatMessageList.
• v5 shells (CometChatConversationsWithMessages, CometChatMessages, CometChatUI, CometChatUserList) — all removed; the host composes screens (→ -migration).

Verify it works

The widget renders and its data populates. Empty ⇒ confirm init + login completed before the screen built (core's gate), and that any list has a bounded height (Expanded).
