Multi count strings

[adamappdev]

I'm trying to implement names string functionality similar to facebook's "Foo, bar and 2 others Likes this" functionality.

here is my json:

"names_plural": {
    "zero": "",
    "one": "{}",
    "two": "{} and {}",
    "three": "{} and {} and {otherCount} other",
    "other": "{} and {} and {otherCount} others"
},

The caller function:

static String names(List<String> ls) {
  return plural(
    'names_plural',
    ls.length,
    args: [
      if (ls.isNotEmpty) ls[0],
      if (ls.length >= 2) ls[1],
    ],
    namedArgs: {
      'otherCount': (ls.length - 2).toString(),
    },
  );
}

And the calls:

print('mt' '\n' + names([]));

print('a' '\n' + names(['a']));

print('a and b' '\n' + names(['a', 'b']));

print('a and b and 1 other' '\n' + names(['a', 'b', 'c']));

print('a and b and 2 others' '\n' + names(['a', 'b', 'c', 'd']));

print('a and b and 3 others' '\n' + names(['a', 'b', 'c', 'd', 'e']));

But apparently there is no three key and it always falls back to other key, how can I be able to implement such a functionality, or should I open a feature request to implement three?
