How to decode JSON in Flutter?

问题很简单，但答案并不简单，至少对我来说是这样.

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

我有一个使用大量 JSON 字符串的项目.基本上，应用程序和服务器之间的整个通信都是通过 JSON 进行的.

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

我一直在使用 JSON.decode(json_string) 来处理它，但今天我更新了 Flutter 核心 (0.5.8-pre.178) 并且 JSON.decode 不再可用.

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.

我去了 Flutter Docs 寻求帮助，但它仍然说要使用 JSON.decode.

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

那么，从现在开始如何在 Flutter 中解码 JSON?

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