TooltipTheme class Null safety

An inherited widget that defines the configuration for Tooltips in this widget's subtree.

Values specified here are used for Tooltip properties that are not given an explicit non-null value.

Here is an example of a tooltip theme that applies a blue foreground with non-rounded corners.

TooltipTheme(
  data: TooltipThemeData(
    decoration: BoxDecoration(
      color: Colors.blue.withOpacity(0.9),
      borderRadius: BorderRadius.zero,
    ),
  ),
  child: Tooltip(
    message: 'Example tooltip',
    child: IconButton(
      iconSize: 36.0,
      icon: const Icon(Icons.touch_app),
      onPressed: () {},
    ),
  ),
)
