记录一些正则匹配 String urlRegExp = r'(?:(?:https?|ftp)://)?[\w/-?=%.]+.[\w/-?=%.]+';String hashtagRegExp = r'(#+[a-zA-Z0-9(_)]{1,})';String userTagRegExp = r'(?<![\w@])@([\w@]+(?:.!+)*)';String emailRegExp =r"([a-zA-Z0-9.a-zA-Z0-9.!#$%&'*+-/=?^_`{|}~]+@[a-zA-Z0-9]+\.[a-zA-Z]+)";

VSCODE开发环境配置之Flutter环境配置 1.官网下载VScode(https://code.visualstudio.com/)2.安装完成后，打开插件中心，搜索对应语言插件（如chinese，japanese）3.安装flutter插件（其他两个也一并安装），同时会提醒你安装dart插件4.安装git（官网：https://git-scm.com/）5.拉取项目如果是windows11，随便选择一个磁盘，鼠标右键，选择“在终端中打开”，接着输入（直接复制粘贴）“git clone 项目地址”，敲下回车，就会开始拉取项目了这表示拉取完成6.使用VScode打开刚才拉取下来的项目，开始开发
