# jsonDecode function

dynamic jsonDecode(

1. String source, {
2. Object? reviver(
   1. Object? key,
   2. Object? value
   )?,

})

Parses the string and returns the resulting Json object.

The optional `reviver` function is called once for each object or list property that has been parsed during decoding. The `key` argument is either the integer list index for a list property, the string map key for object properties, or `null` for the final result.

The default `reviver` (when not provided) is the identity function.

Shorthand for `json.decode`. Useful if a local variable shadows the global json constant.

Example:

    const jsonString =
        '{"text": "foo", "value": 1, "status": false, "extra": null}';

    final data = jsonDecode(jsonString);
    print(data['text']); // foo
    print(data['value']); // 1
    print(data['status']); // false
    print(data['extra']); // null

    const jsonArray = '''
      [{"text": "foo", "value": 1, "status": true},
       {"text": "bar", "value": 2, "status": false}]
    ''';

    final List<dynamic> dataList = jsonDecode(jsonArray);
    print(dataList[0]); // {text: foo, value: 1, status: true}
    print(dataList[1]); // {text: bar, value: 2, status: false}

    final item = dataList[0];
    print(item['text']); // foo
    print(item['value']); // 1
    print(item['status']); // false

## Implementation

    dynamic jsonDecode(
      String source, {
      Object? Function(Object? key, Object? value)? reviver,
    }) => json.decode(source, reviver: reviver);
