singleWhere method
inherited
Returns the single element that satisfies test
.
Checks elements to see if test(element)
returns true. If exactly one element satisfies test
, that element is returned. If more than one matching element is found, throws StateError. If no matching element is found, returns the result of orElse
. If orElse
is omitted, it defaults to throwing a StateError.
Implementation
String singleWhere(bool test(String value), {String orElse()?}) => readClasses().singleWhere(test, orElse: orElse);
