onTertiaryContainer property
A color that's clearly legible when drawn on tertiaryContainer.
To ensure that an app is accessible, a contrast ratio between tertiaryContainer and onTertiaryContainer of at least 4.5:1 is recommended. See www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html.
If null, and if colorScheme.onTertiaryContainer
and [onTertiary) is
null, the color will via ColorScheme default be equal to resulting
color scheme ColorScheme.onSecondary.
Implementation
final Color? onTertiaryContainer;
