For a long list, never use shrinkWrap. Use Expanded when the list is the only scrollable, and slivers (CustomScrollView) when it shares a scroll with other sections. Here is why, with a build-count benchmark.

Put a list and a grid in a single continuous scroll without nested scrollables. Use CustomScrollView with SliverList and SliverGrid, and skip the shrinkWrap trap that quietly kills performance.

Why a ListView in a Column throws 'Vertical viewport was given unbounded height', and the four fixes (Expanded, Flexible, shrinkWrap, SizedBox) with the performance trade-offs that decide which one you want.

Step-by-step migration from Xamarin.Forms 5.0 ListView to .NET MAUI 11 CollectionView for apps that already squeezed performance out of ListView. Covers cell recycling, virtualization, grouping, pull-to-refresh, context actions, selection, ItemsLayout, EmptyView, and the gotchas that bite real apps.
