addFromProps method
Adds the CssClassPropsMixin.className and excludes the CssClassPropsMixin.classNameBlacklist values
if specified within the provided props
Map.
This method gracefully handles null props
, as well as unspecified/null prop values.
This method, along with toProps, are useful for merging sets of className/blacklist props.
Implementation
void addFromProps(Map? props) {
if (props == null) {
return;
}
var cssClassProps = CssClassPropsMapView(props);
this
..add(cssClassProps.className)
..blacklist(cssClassProps.classNameBlacklist);
}
