ChatUiController

1. Add the option showing avatar at the first or the last message in a message group.
   Now, avatar is showing at the last message in a group. But I want to custom it in to showing at the first message.
2. Standart UX of on click/ on hover avatar and User Name are the same(Eg: click to open profile). Now I saw that there is no onClick user name option.
3. Define a ChatUIController that allow handle scroll to index, scroll to messageId, scroll to bottom.
4. Add function onNewMessage(newMessage) to handle new message, and a button scroll to bottom(include new message notification) instead scroll to bottom while received a newMessage.

1. If you check the example app you will see that package user positions avatar - in my example I position it for the last message in the group - but you can position it for the first :)
2. In the same example, Avatar widget I use has optional onTap method. If you don't like it, you can also create your own Avatar.
3. I use package:scrollview_observer/scrollview_observer.dart for the scrollTo functionality, but yes, it needs ot be defined outside (not implemented yet). Scroll to bottom is not a controller responsibility, but a list. And it is already working really nice.

4. instead scroll to bottom while received a newMessage

you could control scrolling to bottom when receiving a message with

Chat(
  builders: Builders(
    chatAnimatedListBuilder: (context, itemBuilder) => ChatAnimatedList(itemBuilder: itemBuilder, shouldScrollToEndWhenAtBottom: false),
  )
)

scroll to bottom should appear automatically I think. onNewMessage(newMessage) is not needed imo, as you add new messages using chat controller, so you know exact moment when you add a message and can run whatever you want at that time.

3. Implemented scroll to index and to message id here, will be released in 2.0.0-dev.7 version ffd6cea

I think that were all question/requests in this discussion, so marking it as solved.
