ChatComposer class

A widget for composing chat messages.

The ChatComposer allows customization of text input areas, including text style, line limits, and decoration. It can also be initialized with a custom builder.

Example with default composer:


@override
Widget build(BuildContext context) {
  return SfChat(
    composer: ChatComposer(
      textStyle: TextStyle(fontSize: 16.0, color: Colors.black),
      minLines: 1,
      maxLines: 6,
      decoration: InputDecoration(
        border: OutlineInputBorder(
          borderRadius: BorderRadius.all(Radius.circular(42.0)))),
        hintText: 'Type a message...',
      ),
      padding: const EdgeInsets.only(top: 16.0),
    )
  );
}

Example with custom Composer:

@override
Widget build(BuildContext context) {
  return SfChat(
    composer: ChatComposer.builder(
      builder: (context) => CustomChatInputWidget(),
      padding: const EdgeInsets.only(top: 16.0),
    )
  );
}
