Flutter localisation method not generating correctly with plural placeholder

Question

I'm currently localizing my flutter app using the intl package.

I have a localised text that contains two placeholders: userName and dayCount, where I have used the plural syntax for dayCount.

Here is the snippet from my .arb file:

  "prolongationRequested": "{userName} requested prolongation by {daysCount, plural, =1{1 day} other{{daysCount} days}}",
  "@prolongationRequested": {
    "placeholders": {
      "userName": {},
      "daysCount": {}
    }
  },

So far so good, but the auto generated method in the AppLocalizationsEn class completely ignores everything from the text except the daysCount placeholder. This is the generated method:

  String prolongationRequested(Object userName, num daysCount) {
    return intl.Intl.pluralLogic(
      daysCount,
      locale: localeName,
      one: '1 day',
      other: '$daysCount days',
    );
  }

My expectation would be for the method to look like this:

  String prolongationRequested(Object userName, num daysCount) {

    final String pluralString = intl.Intl.pluralLogic(
      daysCount,
      locale: localeName,
      one: '1 day',
      other: '$daysCount days',
    );

    return '$userName requested prolongation by ${pluralString}';
  }

Interestingly enough the method gets generated correctly if I remove one of the placeholders, or if I remove the plural syntax from daysCount.

Why is the method not being generated as expected?
