dartx_nullsafety 0.6.0-nullsaftety.0

Superpowers for Dart. Collection of useful static extension methods.

0.5.0

• PR-94 Breaking: Iterable<T>.zip(other, transform) now support zipping iterables of other types the T. This is a breaking change because it is now required to add types in the transform function.

  final amounts = [2, 3, 4];
  final animals = ['dogs', 'birds', 'cats'];
  final all = amounts.zip(animals, (int amount, String animal) => '$amount $animal');
  // lambda types are now required:  ⇧           ⇧
  // all: ['2 dogs', '3 birds', '4 cats']
  

• PR-90 New String extensions
  • String removePrefix(String prefix)
  • String removeSuffix(String suffix)
  • String removeSurrounding({String prefix, String suffix})

  final name = 'James Bond'.removePrefix('James '); // Bond
  final milliseconds = '100ms'.removeSuffix('ms'); // 100
  final text = '<p>Some HTML</p>'.removeSurrounding(prefix: '<p>', suffix: '</p>'); // Some HTML
  

• PR-88 New List extension void swap(int, int) which swaps the elements in the indices provided.

  final list = [1, 2, 3, 4];
  list.swap(0, 2); // [3, 2, 1, 4]
