Chat class

A customizable chat widget that provides a complete chat interface.

This widget follows Clean Architecture principles by separating concerns:

The widget supports:

  • Message display with grouping
  • Custom message bubbles and input fields
  • Scroll behavior and new message notifications
  • Read-only mode

Example usage:

Chat(
  chatController: ChatController(),
  configuration: ChatConfiguration(
    senderAlignment: ChatAlignment.end,
  ),
  onScrollToTop: () async {
    // Load more messages
  },
)
