How to check if int is greater than 1 and make word plural or singular in Flutter?-CodePudding

I would check if the int is greater than 1 and make the word plural or singular. I mean something like the following example:

If the apple variable is 1, it will return:

1 apple

Else:

2 apples

Here's the code of how I do this so far:

"$totalApples ${totalApples > 1 ? "apples" : "apple"}"

But, I think there should be some function or package or other way to solve this problem, right? I wish to use a short code instead of this long code.

How to check if int is greater than 1 and make word plural or singular? I would appreciate any help. Thank you in advance!

CodePudding user response：

yes, there is a plural method in the intl package, check it from here. the Getx package provide same functionality with a plural method.

However, if you want just to make a simple-call method to get the plural, you can use Dart extension methods, like this:

 extension PluralExtension on int { 
  String plural(String singularWord, [String pluralLetters = "s"]) {
    return this > 1 ?  "$this $singularWord$pluralLetters" : "$this $singularWord";  
  }
}

print(5.plural("apple")); // 5 apples
print(0.plural("apple")); // 0 apple
print(1.plural("apple")); // 1 apple
print(10.plural("tomato", "es")); // 1 tomatoes
print(1.plural("tomato", "es")); // 1 tomato

In this example, I added the a custom plural method on the int type, so you can call it simply on anything that's a int.
