like List
and set
, to be use in a range-based for loop with an index.
Usage #
If a class to use this package is based on Iterable

IndexedIterable #
IndexedIterable
offers the ability to provide range-based loop with 0-based index
for Iterable
s like List
and `Set.
import 'package:indexed_iterable/indexed_iterable.dart';
void main() {
final testList = [1,2,3,4,2,2,3,4];
for(final ii in IndexedIterable(testList)) {
print(ii.index);
print(ii.value);
}
}
IndexedMap #
IndexedMap
offers the ability to provide range-based loop with 0-based index
for Map
.
import 'package:indexed_iterable/indexed_iterable.dart';
void main() {
final testMap = {'hi':'hihi', 'bye':'byebye'};
for(final im in IndexedMap(testMap)) {
// im.index => 0-based index
// im.key => key
// im.value => value
}
}
IndexedStream #
IndexedStream
offers the ability to provide range-based async loop with 0-based index
for Stream
.
import 'package:indexed_iterable/indexed_iterable.dart';
void main() async {
/// testStream => some stream you want to handle
for(final im in IndexedStream(testStream)) {
// im.index => 0-based index
// im.value => value
}
}
