Dart pub
Contains a SortedMap and FilteredMap class, which hold a map of objects that can be ordered relative to each other.
Unlike SplayTreeMap the objects can be ordered on both key and value or a combination of both.
The FilteredMap also allows to specify an isValid function on key/value pairs and limit the number of objects
allowed in the map.
A simple usage example:
import 'package:sortedmap/sortedmap.dart';
main() {
var map = new SortedMap((Pair a, Pair b)=>Comparable.compare(a.value, b.value));
map.addAll({
"a": 3,
"b": 2,
"c": 4,
"d": 1
});
print(map.lastKeyBefore("c")); // a
print(map.firstKeyAfter("d")); // b
}
A simple usage example:
import 'package:sortedmap/sortedmap.dart';
main() {
var map = new FilteredMap(new Filter(
compare: (Pair a, Pair b)=>Comparable.compare(a.value, b.value),
isValid: (Pair v) => v.key!="b",
limit: 2));
map.addAll({
"a": 3,
"b": 2,
"c": 4,
"d": 1
});
print(map.keys); // (d, a)
}
