Generating ARB file in intl package does not escape escaped characters

Question

Below is the plural message being used. But, when generating the ARB file, the single quote is not escaping. Similary, I also used double quotes to use the single quotes. That didn't give desired result either.

Intl.plural(
        numberOfOranges,
        zero: "You\'ve got zero orange.",
        one: "You\'ve got $numberOfOranges orange.",
        other: "You\'ve got $numberOfOranges oranges.",
        name: 'getOrangesText',
        args: [numberOfOranges],
      )

ARB: app_en.arb

    "placeholders": {
      "numberOfOranges": {}
    }
  }
}
