This package is specific to Dart extensions, flutter extensions should be added to "FlutterX".

The repository link is currently broken, @leisim will be able to guide you more on this.

I'm using this extension in my projects

import 'package:flutter/widgets.dart';
import 'package:dartx/dartx.dart';

extension WidgetListExt on Iterable<Widget> {
  /// adds widgets between the elements
  List<Widget> dividedWith(Widget divider) {
    final elements = flatMap((it) => [it, divider]).toList();
    // remove last divider
    return elements.dropLast(1);
  }
}

from dartx.

Thanks for the answer. :)
But somewhat somehow I think its relevant to dartx as it should be flexible as possible like the use case below:

final words = <String>[
    'Hello',
    'Flutter',
    'Community',
];

//Accepted value should be based on the generic class type passed
final newWords = words.dividedWith(' ');
