VSCode 中自定义代码片段

1. 打开 VScode ，选择 User Snippets

选择对应模板下 json 配置文件, 打开如下

{
    // Place your snippets for dart here. Each snippet is defined under a snippet name and has a prefix, body and 
    // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
    // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
    // same ids are connected.
    // Example:
    // "Print to console": {
    //  "prefix": "log",
    //  "body": [
    //      "console.log('$1');",
    //      "$2"
    //  ],
    //  "description": "Log output to console"
    // }
}

2. 利用在线的网站生成工具，生成文件
