The CometChat V6 UI Kit provides CometChatOutgoingMessageBubbleStyle and CometChatIncomingMessageBubbleStyle for fine-grained control over message bubble appearance. These classes extend ThemeExtension, allowing customizations through global theming or explicit style objects.

​
How These Classes Help

​
1. Targeted Customization

Customize specific attributes of message bubbles:
  • Background color, border radius, text style
  • Specialized bubbles: Audio, File, Collaborative, Poll, Deleted, Link Preview, Sticker, Call bubbles
  • Reactions, timestamps, avatars, and borders

​
2. Unified Global Theming

Apply styles via Flutter’s global theming or pass them to CometChatMessageListStyle: 
MaterialApp(
  title: 'Your app',
  theme: ThemeData(
    extensions: [
      CometChatIncomingMessageBubbleStyle(
        backgroundColor: Color(0xFFF76808),
      ),
      CometChatOutgoingMessageBubbleStyle(
        backgroundColor: Color(0xFFF76808),
      ),
    ],
  ),
  home: ...,
);

​
3. Ease of Integration

Pass styles directly to CometChatMessageList: 
CometChatMessageList(
  user: user,
  group: group,
  style: CometChatMessageListStyle(
    incomingMessageBubbleStyle: CometChatIncomingMessageBubbleStyle(),
    outgoingMessageBubbleStyle: CometChatOutgoingMessageBubbleStyle(),
  ),
)
