TooltipTheme class
Applies a tooltip theme to descendant Tooltip widgets.
A tooltip theme describes the values to use for Tooltip properties that are not given an explicit non-null value.
Descendant widgets obtain the ambient tooltip theme, a TooltipThemeData, using TooltipTheme.of.
Here is an example of a tooltip theme that applies a blue foreground
with non-rounded corners.
