Question

How to decode JSON in Flutter?

The question is simple, but the answer isn't, at least for me.

I have a project that uses a lot of JSON Strings. Basically, the entire communication between the app and the server is through JSON.

I have been using JSON.decode(json_string) to deal with it, but today I updated the Flutter core (0.5.8-pre.178) and JSON.decode isn't available anymore.

I went to the Flutter Docs to seek help, but it still says to use JSON.decode.

So, how to decode JSON in Flutter from now on?

Answer 1

Just use

json.decode()

or

jsonDecode()

In Dart 2 all screaming-case constants were changed to lower-camel-case.

Ensure to import 'dart:convert';
