How to escape single quote in flutter's .arb files?

I have the following in my intl_en.arb file:

"title_chef_selection": "Chef's Selection",
"@title_chef_selection": {},

And I get this error: Error: Unbalanced escape quotes. To escape a single quote ', prefix it with another single quote.(mismatched_brackets)

I followed it’s advice changing it to this:

"title_chef_selection": "Chef''s Selection",
"@title_chef_selection": {},

This shows two single quotes in Text(S.of(context).title_chef_selection)

I just tried this one:

"title_chef_selection": "Chef's Selection",
"@title_chef_selection": {},

I get this error: Invalid escape character in string.json(261), but it works and the text shows properly. Is there a different way of doing it or a way to get rid of the error?
