为 Zed 编辑器 添加 flutter dart snippets

zed 添加 snippets 和 vscode 的 snippets 看起来非常的像，官方文档示例地址如下：zed.dev/docs/snippe…

参考了 宁浩 老师的 vscode snippets ： github.com/ninghao/vsc…

为 zed 添加 snipptes 步骤如下：

• command + shift + p 或者用 菜单 go-> command palette..., 然后输入 snippets: configure snippets 回车确定

• select snippets scope 输入 dart

回车确定会打开 dart.json, 把如下代码复制粘贴进入你 zed 配置文件里面

其中前三个是 和 vscode 的 flutter 扩展带来的 snippets 完全一致, 即在vscode里面打开 .dart为后缀的文件，输入小写 字母 s 触发，新建的 .dart 文件需要保存一下， 你要安装的有 flutter 扩展。
