How do you get a formatted/indented JSON String from a JSON object?

Question

Using dart:convert I can get an unindented string with this code.

var unformattedString = JSON.encode(jsonObject);

How do I take a JSON object and convert it to an indented string?

Answer 1

One way to do it is by creating a JSONEncoder.withIndent instance.

String getPrettyJSONString(jsonObject){
   var encoder = new JsonEncoder.withIndent("     ");
   return encoder.convert(jsonObject);
}

Answer 2

Use this. it worked for me

String prettyJson(dynamic json) {
    var spaces = ' ' * 4;
    var encoder = JsonEncoder.withIndent(spaces);
    return encoder.convert(json);
}
