Anchor.valueOf constructor
Anchor.valueOf(
- String name
This should only be used for de-serialization purposes.
If you need to convert anchors to serializable data (like JSON),
use the toString()
and valueOf
methods.
Implementation
factory Anchor.valueOf(String name) {
if (_valueNames.containsValue(name)) {
return _valueNames.entries.singleWhere((e) => e.value == name).key;
} else {
final regexp = RegExp(r'^\Anchor\(([^,]+), ([^\)]+)\)');
final matches = regexp.firstMatch(name)?.groups([1, 2]);
assert(
matches != null && matches.length == 2,
'Bad anchor format: $name',
);
return Anchor(double.parse(matches![0]!), double.parse(matches[1]!));
}
