Can you add a comma to a VS Code Snippet placeholder option?

Question

I want to create a VS Code snippet that uses the choices feature:

"Fool's Dart Types": {
        "scope": "dart",
        "prefix": "foolsTypes",
        "body": [
            "${1|bool,String,int,double,num,List<Map<String, dynamic>>,Map<String, dynamic>,dynamic|} ${2:variableName};"
        ]
    },

The issue is that the commas inside my List and Map choices break up the choices so they look like this:

I tried using the \ character but that doesn't work inside the choices brackets.

Answer 1

I was using the \ wrong. You have to use 2 backslashes to escape the characters so doing this works:

"Fool's Dart Types": {
        "scope": "dart",
        "prefix": "foolsTypes",
        "body": [
            "${1|bool,String,int,double,num,List<Map<String\\, dynamic>>,Map<String\\, dynamic>,dynamic|} ${2:variableName};"
        ]
    },
