What does it do?

This PR implements the typing indicator which is missing from the package. The current change allow Chat widget to add optional typing indicator. It takes List<types.User> as a parameter which by default is empty. When empty, it also doesn't show any indicator. When we have more than 2 users in list, it shows small count bubble, otherwise it'll show two users avatars actively typing and indicator. The indicator widget has support of customization in the form of bubbleBorder, bubbleColor, animatedCircleColor, ForwardAnimationDuration and ReverseAnimationDuration to control animation duration of indicator circles. A lot of has been commented as per your pattern in the code.

Why is it needed?

This is most useful for people who want to show typing indicator in their chat implementations. I believe it'll help to make package even better.

How to test it?

From the example code. We can add users list as a parameter for showTypingIndicator(). By default its disabled and takes empty list.

This PR relates to #269.

This adds the ability to send audio messages in the chat by integrating the flutter_sound package. I tried to make it independent at first, to do what you did for images or attachments, with a few callbacks to let the user implement that part on their own, but since the recording interface has to be deeply integrated with the input bar, it didn't really make sense.

I demonstrated the new feature in the example app, and added some "advanced usage" documentation.

Let me know what you think.

For over a month the new features development was blocked by the animated version of chat UI where we faced particular bottlenecks while working with list animations in Flutter. As a result - lack of updates from our side. That's why we are merging issues #7, #9 and #20 into one for a more convenient progress tracking.

v1.1 will have 👉

• [x] Animated chat UI
• [x] Updated date dividers
• [x] Updated message statuses
• [x] Ability to display user name & avatar
• [x] Pagination

💬 From now on all new updates will be shared by @demchenkoalex here.

What does it do?

Add simple markdown rendering and replace link renderer with it too. Closes #157

Why is it needed?

Most modern chat apps have markdown support. Also, it is a bit cumbersome to maintain the header + text rendering logic here and in the link previewer package as well. Now, it is unified across both.

How to test it?

I added a simple Markdown example in the example app with link and email as well.

Open Questions / TODO

• Should there be an option to disable Markdown formatting in the Chat constructor?

What does it do?

Implement directionality where if the text direction is RTL everything moves according to it. I also added Arabic Localization as ChatL10nAr

Why is it needed?

The chat to be useable in RTL languages the bubbles and buttons need to be swapped by the Y-axis

How to test it?

Wrap the Chat widget with Directionality and change TextDirection from ltr to rtl to see the effect. ex:

Directionality(
    textDirection: TextDirection.rtl,
    child: Chat()
)

What does it do?

Add an unread messages banner and the option to scroll to the first unread message on chat open.

Why is it needed?

Users should have a way of being brought directly to the content they need to see most urgently. In many cases this is the first unread message.

How to test it?

In the example app, I have set scrollToUnseenOnOpen so it should immediately scroll to the first message.

Closes #179 and closes #213

This is built on top of #208 and should not be merged before it. Second part of #179.

Open Questions / TODO

• [x] Should there be an option to disable the banner too?
• [x] Designer: I need designs for the banner and then I can also make them configurable in the ChatTheme
• [x] I will write some tests for my changes to the 'util' function
• [x] The unseen message calculation currently only works if the status is set correctly for each message. I wonder whether the statuses for received messages are even really relevant and can be used like this. Wouldn't it make more sense to have a seenBy array on messages to check for the first message which is not marked as seen by the current user?
• [x] Scroll to bottom indicator (separate issue, tackle later)

It is a normal use case to reply directly to a specific message, when this happens, it usually displays a snippet of the old message to give context.

Examples: Telegram:

Whatsapp:

I'm using just the sample code provided in your documentation and when I try the link you provide to test (https://bit.ly/2P0cn2g), I don't see a preview, just an extra space:

Hi,

first of all congratulations on developing this great package....

I have couple of questions...

1. How mark messages deliver and read.....
2. How to customize shape and color of Chat bubble to match my theme....
3. Customize Bottom chat Send Bar and ....
4. Is there a way to group messages by date similar to WhatsApp with Date banner...?

I followed example code from here and didn't find much helpful information related to customization.... https://pub.dev/packages/flutter_chat_ui/example

Thank you very much for your precious job!

I'm wondering if it is possible to open the chat at the first unseen message, instead of the more recent one in the chat (at the bottom of it).

Maybe manually set the scroll offset value (ScrollController.initialScrollOffset inside ChatList, but it's internal)?

I tried to view the code and I couldn't manage to find out a solution, but I'm a really amateur and so I'm not sure of myself.

Thank-you very much!

A really simple change: if the user provides a 'WidgetBuilder inputBuilder' argument, that is used to render the input. Makes it easier to reuse and restyle for your project.

Thoughts?

Hey! Hen I try to type message, keyboard covers half of the chat screen, but it doesn't move up with keybaord but stay under it. Then I can see messages after unfocusing and hiding keyboard

Here's my code

@override Widget build(BuildContext context) { chatController.roomModel = room; return Scaffold( appBar: AppBar( leading: IconButton( icon: const Icon(Icons.arrow_back_ios_new_rounded, color: Colors.black), onPressed: () => Navigator.of(context).pop(), ), toolbarHeight: 75.0, backgroundColor: Colors.white, elevation: 0, title: Text( "${chatRoomsController.roomModel.name}", style: const TextStyle( color: Colors.black, fontSize: 30.0, fontWeight: FontWeight.w900), ), ), body: GestureDetector( behavior: HitTestBehavior.opaque, onTap: () => FocusScope.of(context).unfocus(), child: StreamBuilder<types.Room>( initialData: chatRoomsController.roomModel, stream: FirebaseChatCore.instance .room(chatRoomsController.roomModel.id), builder: (context, snapshot) { return StreamBuilder<List<types.Message>>( initialData: const [], stream: FirebaseChatCore.instance.messages(snapshot.data!), builder: (context, snapshot) { return SafeArea( //bottom: false, child: Chat( l10n: const ChatL10nPl( emptyChatPlaceholder: "Wyślij pierwszą wiadomość"), showUserNames: true, showUserAvatars: true, disableImageGallery: true, emojiEnlargementBehavior: EmojiEnlargementBehavior.multi, hideBackgroundOnEmojiMessages: false, theme: const DefaultChatTheme( deliveredIcon: Icon(Icons.check_circle_outline_rounded), messageInsetsVertical: 12, userAvatarNameColors: [Colors.black], inputBorderRadius: BorderRadius.vertical(top: Radius.circular(6)), inputBackgroundColor: Color.fromARGB(255, 205, 252, 207), inputTextColor: Color.fromARGB(255, 65, 161, 68), primaryColor: Color.fromARGB(255, 205, 252, 207), sentMessageBodyTextStyle: TextStyle( color: Color.fromARGB(255, 95, 95, 95), fontWeight: FontWeight.bold)), messages: snapshot.data ?? [], onMessageTap: chatController.handleMessageTap, onPreviewDataFetched: chatController.handlePreviewDataFetched, onSendPressed: chatController.handleSendPressed, keyboardDismissBehavior: ScrollViewKeyboardDismissBehavior.manual, user: types.User( id: FirebaseChatCore.instance.firebaseUser?.uid ?? '', ), ), ); }, ); }, ))

state: ready to be merged

Hello 👋, I'm using your amazing Package To create a chat in my app.

This PR is not to fix the issue but adding a new feature I was facing a problem, if the chat is new The messages start from the bottom usually in famous chatting apps like (WhatsApp, Messenger, etc..,). They start from the top so I added this feature by just adding a simple flag in the chat Widget, this flag changes the value of shrinkWrap in CustomScrollView and makes the column main axis alignment -> MainAxisAlignment.space-between if it is true

What does it do?

Add an ability to control a text input field's keyboard type (multiline/number/email/etc.)

Why is it needed?

Sometimes developers need to pre-define an input keyboard type to a specific type. For example, a user should only type numbers in a quiz game.

Especially in group chats, many modern chat apps have mentioning feature. Let's say we have a list of Users for our group chat. When the user types @ in to the chat text field, we should show the list of users in a popup. And when the user keeps typing letters, we should filter the users according to the filter text. If the user chooses one of the suggested users to mention, that user name should have a different style in the text field, telling the user that they will be mentioned.

I know there are separate packages for the UI which do these. If you think this is a good addition and want more info I can supply more resources.

Thanks for this great package.
