Multi-step tooltip onboarding tours in Flutter are created using OverlayEntry to render UI above existing screens and Cubit/Bloc state management to drive step progression across multiple routes. GlobalKeys track target widgets for precise highlighting.

Snapshot highlighting for Flutter tooltips works by assigning GlobalKeys to target widgets, capturing their position and dimensions to render an accurate OverlayEntry highlight box directly over the specified UI element.

Yes, you can use Bloc or Cubit for step control in Flutter tooltip tours to manage state progression. They handle advancing through onboarding sequences, updating overlay visibility, and safely disposing subscriptions when tours finish.

The best way to manage OverlayEntry lifecycle during a Flutter onboarding sequence is implementing safe lifecycle handling with route checks, timers, and subscription disposal to remove overlays and prevent memory leaks when tours end.

Flutter tooltip overlays disappear on route navigation due to missing route checks within lifecycle handling. Implementing route verification before rendering OverlayEntry ensures safe disposal and prevents context errors when users navigate away mid-tour.
