Add widget to header to working

[Inihood1]

I get the following error when adding a widget to the "header"

======== Exception caught by widgets library =======================================================
The following assertion was thrown while rebuilding dirty elements:
'package:flutter/src/widgets/framework.dart': Failed assertion: line 4479 pos 14: 'owner!._debugCurrentBuildTarget == this': is not true.

you need to wrap your widget with SliverToBoxAdapter :)
