onSuggestionItemSelected property

ChatSuggestionItemSelectedCallback? onSuggestionItemSelected

Optional callback function that will be executed when the suggestion is selected.

The onSuggestionItemSelected callback is triggered when the user selects a suggestion from the suggestion list. This callback provides details about the selected suggestion, suggestion index, and the message index.

When a suggestion is selected, you can use this callback to update the UI to reflect the selected state of the suggestion and the selected suggestion is added as a new message in the conversation area.

@override
Widget build(BuildContext context) {
  return SfChat(
    onSuggestionItemSelected:
        (selected, messageIndex, suggestion, suggestionIndex) {
      setState(() {
        _messages[messageIndex].suggestions![messageIndex] =
            suggestion.copyWith(selected: true);
        _messages.add(
           ChatMessage(
             text: _messages[messageIndex]
                   .suggestions![messageIndex]
                   .data!,
             time: DateTime.now(),
             author: const ChatAuthor(
               id: 'a2c4-56h8-9x01-2a3d',
               name: 'Incoming user name',
             ),
           ),
        );
      });
    },
  );
}
