json decode list flutter

To decode a JSON list in Flutter, you can use the json.decode() function from the dart:convert package. Here's an example of how to do it:

import 'dart:convert';

void main() {
  String jsonString = '[1, 2, 3, 4, 5]';
  List<dynamic> decodedList = json.decode(jsonString);

In this example, we start by importing the dart:convert package. We then define a JSON string jsonString that represents a list of numbers [1, 2, 3, 4, 5].

Next, we use the json.decode() function to parse the JSON string into a Dart object. The json.decode() function returns a dynamic object, so we explicitly define the type of the decoded object as List<dynamic>.

Finally, we print the decoded list using print(decodedList).

When you run this code, you will see the decoded list [1, 2, 3, 4, 5] printed in the console.

Note that the json.decode() function can also be used to decode other kinds of JSON objects, such as maps or custom objects. The type of the decoded object will depend on the structure of the JSON data you are decoding.
