Message Composer

Overview

CometChatMessageComposer is a Widget that enables users to write and send a variety of messages, including text, image, video, and custom messages. Features such as Live Reaction, Attachments, and Message Editing are also supported by it.

CometChatMessageComposer is comprised of the following Base Widgets:

Base Widgets	Description
MessageInput	This provides a basic layout for the contents of this component, such as the TextField and buttons
ActionSheet	The ActionSheet widget presents a list of options in either a list or grid mode, depending on the user’s preference

Usage

Integration

You can launch CometChatMessageComposer directly using Navigator.push, or you can define it as a widget within the build method of your State class.

1. Using Navigator to Launch `CometChatMessageComposer`

Navigator.push(context, MaterialPageRoute(builder: (context) => CometChatMessageComposer())); // A user or group object is required to launch this widget.

2. Embedding `CometChatMessageComposer` as a Widget in the build Method

import 'package:cometchat_chat_uikit/cometchat_chat_uikit.dart';
import 'package:flutter/material.dart';

class MessageComposer extends StatefulWidget {
  const MessageComposer({super.key});

  @override
  State<MessageComposer> createState() => _MessageComposerState();
}

class _MessageComposerState extends State<MessageComposer> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: SafeArea(
            child: Column(
              children: [
                const Spacer(),
                CometChatMessageComposer()
              ],
            ) // A user or group object is required to launch this widget.
        )
    );
  }
}

Actions

Actions dictate how a widget functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the widget to fit your specific needs.

1. OnSendButtonClick

The OnSendButtonClick event gets activated when the send message button is clicked. It has a predefined function of sending messages entered in the composer EditText. However, you can overide this action with the following code snippet.

CometChatMessageComposer(
  user: user,
  onSendButtonTap: (BuildContext context, BaseMessage baseMessage, PreviewMessageMode? previewMessageMode) {
    // TODO("Not yet implemented")
  },
)

2. onChange

This action handles changes in the value of text in the input field of the CometChatMessageComposer widget.

CometChatMessageComposer(
  user: user,
  onChange: (String? text) {
    // TODO("Not yet implemented")
  },
)

3. onError

This action doesn’t change the behavior of the widget but rather listens for any errors that occur in the MessageList widget.

CometChatMessageComposer(
  user: user,
  onError: (e) {
    // TODO("Not yet implemented")
  },
)

Filters

CometChatMessageComposer widget does not have any available filters.

Events

Events are emitted by a Widget. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. The CometChatMessageComposer Widget does not emit any events of its own.

  user: user,
  textFormatters: [
    CometChatMentionsFormatter(

    return [
      CometChatMessageComposerAction(

        title: "Send Image",
        iconUrl: "assets/img/envelope.png",
        onItemClick: (BuildContext context, User? user, Group? group) {

        }
      ),
      CometChatMessageComposerAction(
          id: 'opt1',
