How to format a multi line string with triple quotes inside in JSON file?

Question

I have markdown string to store in json file, so I am using multi line and so many things in the string. How can I store it in json object?

[
  { "title":  "Title of Ebook",
    "details": [
      {
        "head": "Introduction 1",
        "data": """It’s important to follow trends in your field to ensure you’re staying current on standards and protocols and perhaps more so in the field of coding. Programmers of all specialties can benefit from following

      }
  }
]

When I will receive the string I will have the markdown style data from json.

Your object is not closed correctly. There are closing brackets missing.

Not sure if it answers your question but you can do it like this:

import 'dart:convert';

main(List<String> arguments) {
  var json = [
    {
      "title": "Title of Ebook",
      "details": [
        {
          "head": "Introduction 1",
          "data":
              """It’s important to follow trends in your field to ensure you’re staying current on standards and protocols and perhaps more so in the field of coding. Programmers of all specialties can benefit from following

        }
      ]
    }
  ];

  var encodedJson = jsonEncode(json);

  print(encodedJson);

  var details = json[0]['details'] as List;
  print(details[0]['data']);
}

There is no need for triple quotation in your JSON file. If you decode the written JSON file, the corresponding strings will be equal. — SebastianK, Nov 04 '19 at 15:51
