Flyouts, Tabs, and Popups in One .NET MAUI App

Written for .NET MAUI UI July 2026, Mark Laureta walks through Food Delivery, the showcase app for MvvmEssentials, a navigation and MVVM library he built as an alternative to Shell. Each screen highlights a different piece of the framework.

What you’ll learn

• A unified lifecycle contract — a PageViewModel base with hooks like OnParametersSet, OnNavigatedTo/From, and OnInitialized shared across surfaces
• Flyout + tabs shell — composing a FlyoutPage with a nested TabbedPage, and behaviors that fix lifecycle propagation into the detail
• Once vs. every time — deciding between OnInitialized and OnNavigatedTo/OnTabSelected for loading data
• Typed navigation — passing typed parameters instead of route strings, with auto-mapped properties
• Popups that return results — awaiting a typed result from a popup instead of callbacks or shared state
• Registering it all — wiring pages, tabs, and popups with a fluent MapPage/RegisterPage registry
