Could be. In this case following the same pattern done with the changes in DatePicker (handler, tests etc): https://github.com/dotnet/maui/blob/net10.0/src/Controls/tests/Core.UnitTests/DatePickerUnitTest.cs#L179

Ok, we might want to create a couple of more tests with these variables taking null and everything works too.
