AstryxTheme class
Makes an AstryxThemeData available to the widgets beneath it.
Usually installed by AstryxApp or AstryxThemeProvider rather than
directly. Use it on its own to re-theme a subtree — an inverted toolbar, a
preview pane showing another theme.
{@tool snippet}
AstryxTheme(
data: myThemeData,
child: const MyPane(),
)
{@end-tool}
See also:
AstryxThemeProvider, which resolves a theme from a definition and installs this along with the icon registry and localisations.
