onPrimaryContainer property
A color that's clearly legible when drawn on primaryContainer.
To ensure that an app is accessible, a contrast ratio between primaryContainer and onPrimaryContainer 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.onPrimaryContainer
is null, the color
will via ColorScheme default be equal to resulting color scheme
ColorScheme.onPrimary.
Implementation
final Color? onPrimaryContainer;
