Chat application hangs once we continuously send messages

[swarupa-v]

Hello,

We were developing chat application using flyer chat with firebase. We are facing an issue when sending a new messages when there are many messages present in the chat thread. We are using stream-builder to display real time messages.
As soon as we send the message, stream builder loads the messages again and it leads to memory leak. Eventually it leads to screen freezing due to memory leak. This happens when we keep sending messages continuously.

When we call this function FirebaseChatCore.instance.sendMessage it slows down may be because all messages are fetched again.
