附加信息
On investigation, the problem reported is actually caused by .NET MAUI. For .NET MAUI, layout passes are greatly inconsistent and are the cause most layout bugs in reported for .NET MAUI.
When using StackLayout, it is always necessary to set a size on the control. When no height is provided, the behavior of StackLayout will cause the control to size itself to the smallest size it can be, which on Android is 0. This explains when using a Grid within the StackLayout with HeightRequest/WidthRequest or setting Height/Width on the MapView, resolves the issue. Note, setting MinimumHeight / MinimumWidth will always result in the control adopting that size, never larger, therefore we recommend setting an explicit size (Height/Width). Also note, when not setting properties explicitly and instead relying on default behaviors, results may vary across the platforms supported by .NET MAUI.
Thus, to overcome this .NET MAUI behavior/problem, it is suggested the MapView must have a minimum or specific size.
