Hi so I was doing an app like uber but I got an error of this. I'm new in using flutter. Before this, I can run app this normally but suddenly I got this error this morning. This is my code. Can someone help me?
this is the error
A build function returned null. The offending widget is: StreamBuilder To return an empty space that causes the building widget to fill available room, return "Container()". To return an empty space that takes as little room as possible, return "Container(width: 0.0, height: 0.0)".
