textDecoration static method
Returns a TextDecoration from the specified list or string.
If the key identifies a list, then each entry in the list is decoded by recursively invoking textDecoration, and the result is the combination of those TextDecoration values as obtained using TextDecoration.combine.
Otherwise, if the key identifies a string, then the value lineThrough
is
mapped to TextDecoration.lineThrough, overline
to
TextDecoration.overline, and underline
to TextDecoration.underline.
Other values (and the abscence of a value) are interpreted as
TextDecoration.none.
Implementation
static TextDecoration textDecoration(DataSource source, List<Object> key) {
final List<TextDecoration>? decorations = list<TextDecoration>(source, key, textDecoration);
if (decorations != null) {
return TextDecoration.combine(decorations);
}
switch (source.v<String>([...key])) {
case 'lineThrough':
return TextDecoration.lineThrough;
case 'overline':
return TextDecoration.overline;
case 'underline':
return TextDecoration.underline;
default:
return TextDecoration.none;
}
}
