corextensions 1.1.1

Many helpful extensions to the core classes like string and iterable.

Corextensions

The corextensions package is made up of many extensions on core classes such as String, List and Iterable.

Getting Started

To import this package, include the following code:

import 'package:corextensions/corextensions.dart';

Example Properties

For example, the following lists a few of these extensions:

• Iterable.isSingle returns true if an iterable has length 1.
• Iterable.smallestWhere returns the smallest value in this iterable following a mapping to num.
• Iterable.hasSameLengthAs returns true if the length of this iterable is the same as the other iterable provided.
• Iterable.count returns the number of times a value is present in the iterable.
• List.mapWithIndex returns an iterable which has been mapped using this list, where we are provided with both the value at the index, and the index itself.
• List.hasDuplicates returns true if the list has an element present more than once, checked by the equality operator ==.
• List.swap swaps two elements within the list.
• List.allIndicesOf returns all the indices of a value in the list.
• Set.equals returns true if this set has the same values as the other set, in any order.
• Iterable.sumWhere returns the sum of elements in the iterable following a function returning a number.
• String.capitalise returns the string with the first letter replaced with the original one in upper case.
• String.removeExtraSpace returns the string with whitespace removed from not just the start and the end, but also the middle, with the assumption that there should only be 1 space between 2 words.
• String.splitByAll splits the string by all the delimiters provided.
• String.replaceLast replaces the last occurence of a substring from the string.
• Map.firstValueWhere returns the first value that satisfies the provided function.
• Map.reverse flips keys and values.

On top of these, there is also the function zipTwoLists which zips two lists in the provided order.

Examples using these properties can be found in the example section.
