Delay in List view display when sender sends a message.

[charan-mudiraj]

The list view is built by the StreamBuilder widget. When the sender sends a message the message is being uploaded and then displayed into the list view.(hence the delay)

This could be resolved by using a local list. The new messages from the sender will be first added to this local list and the same list will be updated when the stream list view gets updated. But the updating phase gives a flick in list view, due to clearing and rebuilding the local list with the updated one.

Couldn't resolve that flick.
