======== Exception caught by widgets library =======================================================
The following assertion was thrown building MainScreen(dirty, dependencies: [FlAppwriteAccountKit]):
setState() or markNeedsBuild() called during build.

This Overlay widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase.
The widget on which setState() or markNeedsBuild() was called was: Overlay-[LabeledGlobalKey<OverlayState>#c5b77]
  state: OverlayState#cee5b(entries: [OverlayEntry#62e83(opaque: true; maintainState: false), OverlayEntry#a96c4(opaque: false; maintainState: true), OverlayEntry#82e01(opaque: false; maintainState: false), OverlayEntry#fdc08(opaque: false; maintainState: true)])
The widget which was currently being built when the offending call was made was: MainScreen
  dirty
  dependencies: [FlAppwriteAccountKit]
The relevant error-causing widget was: 
  MainScreen MainScreen:file:///Users/ruslan/StudioProjects/wizard_game/lib/main.dart:20:15

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:

Sorry it was my mistake.
