Cometchat Flutter V5 Conversations

CometChat Flutter UIKit v5 — Conversations

The CometChatConversations component displays a list of recent conversations.

Key Props

Basic Usage

CometChatConversations(
  onItemTap: (conversation) {
    User? user;
    Group? group;
    if (conversation.conversationWith is User) {
      user = conversation.conversationWith as User;
    } else {
      group = conversation.conversationWith as Group;
    }
    Navigator.push(context, MaterialPageRoute(
      builder: (_) => MessagesScreen(user: user, group: group),
    ));
  },
)

Custom Request Builder

CometChatConversations(
  conversationsRequestBuilder: ConversationsRequestBuilder()
    ..limit = 30
    ..conversationType = ConversationType.user,
)

Internal Architecture (GetX)

The component creates CometChatConversationsController via Get.put() in initState() and deletes it in dispose() (unless controllerTag is provided externally).

Theme values are cached in didChangeDependencies() (unconditionally, no flag):

@override
void didChangeDependencies() {
  typography = CometChatThemeHelper.getTypography(context);
  colorPalette = CometChatThemeHelper.getColorPalette(context);
  spacing = CometChatThemeHelper.getSpacing(context);
  style = CometChatThemeHelper.getTheme<CometChatConversationsStyle>(
      context: context, defaultTheme: CometChatConversationsStyle.of)
    .merge(widget.conversationsStyle);
  super.didChangeDependencies();
}

Anti-Patterns

// ❌ WRONG — trying to access controller before component mounts
final controller = Get.find<CometChatConversationsController>();

// ❌ WRONG — manually creating controller outside the widget
Get.put(CometChatConversationsController(...));

// ❌ WRONG — not extracting User/Group from conversation
onItemTap: (conversation) {
  Navigator.push(context, MaterialPageRoute(
    builder: (_) => MessagesScreen(user: conversation.conversationWith), // Type error
  ));
}

Checklist — Conversations

• [ ] onItemTap extracts User/Group from conversation.conversationWith with type check
• [ ] Navigation to messages screen passes extracted user or group
• [ ] Let the widget manage its own GetX controller lifecycle
