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.

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: () {},
    ),
  ),
)
