DialogTheme class Null safety

Defines a theme for Dialog widgets.

Descendant widgets obtain the current DialogTheme object using DialogTheme.of(context). Instances of DialogTheme can be customized with DialogTheme.copyWith.

When Shape is null, the dialog defaults to a RoundedRectangleBorder with a border radius of 2.0 on all corners.

titleTextStyle and contentTextStyle are used in AlertDialogs. If null, they default to TextTheme.headline6 and TextTheme.subtitle1, respectively.
