Simple delegate for Indexed Itrables

This simple package offers a delegates to represent an Iterable, 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 class, then you can use this package as follows.

See the API references for the details.

IndexedIterable

IndexedIterable offers the ability to provide range-based loop with 0-based index for Iterables 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
  }
}
