E/flutter ( 7192): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled

E/flutter ( 7192): This error happens if you call setState() on a State
object for a widget that no longer appears in the widget tree (e.g., whose
parent widget no longer includes the widget in its build). This error can
occur when code calls setState() from a timer or an animation callback.
E/flutter ( 7192): The preferred solution is to cancel the timer or stop
listening to the animation in the dispose() callback. Another solution is
to check the "mounted" property of this object before calling setState() to
ensure the object is still in the tree.
E/flutter ( 7192): This error might indicate a memory leak if setState()
is being called because another object is retaining a reference to this
State object after it has been removed from the tree. To avoid memory
leaks, consider breaking the reference to this object during dispose().

@pradeep14598 the DashboardController is missing, could you make it runnable first in one single file? |
https://gist.github.com/pradeep14598/b191d0bacd5ae9d67d1e6094152a4183 |

@pradeep14598 you shouldnt put your you should put at here class Test extends StatefulWidget {
final String? title;
final GlobalKey<ScaffoldState> _scaffoldkey = new GlobalKey<ScaffoldState>();
Test({@required this.title});
@override
_TestState createState() => _TestState();
}
class _TestState extends State<Test> {
@override
Widget build(BuildContext context) {
}
}
