IconThemeData class

Defines the size, font variations, color, opacity, and shadows of icons.

Used by IconTheme to control those properties in a widget subtree.

To obtain the current icon theme, use IconTheme.of. To convert an icon theme to a version with all the fields filled in, use IconThemeData.fallback.
