UserTypingStateStream class

Notification class for features like watching and streaming user typing activity and other related features.

Sample Code Below:

StreamBuilder(
  stream: UserTypingStateStream.instance.isTypingStream,
    builder: (context, data){
      if(data.hasData && data.data == true){
        return const Text('Typing');
      }else{
        return const SizedBox.shrink();
      }
    }
  )
)

So with the above, you can do whatever you want.

Like sending the event to the server and listening to it at the other users end to notify in chat
