HeroIconTheme class

Similarly to IconTheme, you can set the default options for all icons. Simply add HeroIconTheme to the widget tree, ideally as close to your MaterialApp as possible:

MaterialApp(
  // ...
  child: HeroIconTheme(
    style: HeroIconStyle.solid,
    child: // ...
  ),
),

If a HeroIconTheme exists as an ancestor of a HeroIcon, the properties on the theme will be used as defaults - if they are not specified on the HeroIcon.

Static Methods

maybeStyleOf(BuildContext context) HeroIconStyle?
Attempts to get the style from an ancestor HeroIconTheme widget. If this is found, the style is returned - otherwise null is returned and a fallback may be determined.
shouldUseSemanticLabel(BuildContext context) bool
styleOf(BuildContext context) HeroIconStyle
Assumes that there is an ancestor HeroIconTheme theme and gets the style property from it. If there is, in fact, no ancestor, an exception is thrown.
