Flutter配置for Mac -- VSCode（flutter配置Universal Link）

最近开始了解Flutter，下面介绍在Mac环境下配置开发环境，我是一个iOS开发者，所有以后的系列文章都会以iOS的开发角度去学习Flutter。大家一块学习

配置Flutter-SDK

1：解压压缩包，以我个人配置为例，放到文档中，并且创建一个文件夹Flutter，且把解压后的文件放入该文件夹中。

2：配置环境路劲

配置环境变量,使用命令行：

 `cd`到上一步的路劲 

执行

vim ~/.bash_profile

保存并退出（啥事不用干）保存之后执行如下命令

export PATH=`pwd`/flutter/bin:$PAT

保存一下，注意如果这个文件不存在，那么就新建一个。保存完毕之后运行命令:

source ~/.bash_profile

这个时候应该能运行flutter命令了，我们运行命令行：

flutter -h

执行完命令后出现如下日志

NOTICE:按照检测结果的说明，如果有[!] ? 标志，表示本行检测不通过，需要做一些设置或者安装一些软件。因为我是iOS开发者，所以只针对iOS开发体系

所有看上面有提示x的所以就执行每一行提示的指令

依次执行完成即可

NOTICE不同用户看到信息不用，请酌情处理

到此执行已经配置完成了。

配置VSCode

vscode配置如图

NOTICE:注意如图上得箭头，选择放置Flutter的文件夹选择bin文件夹的路劲即可

创建新的应用

1. 启动 VS Code
2. 调用 View>Command Palette…
3. 输入 ‘flutter’, 然后选择 ‘Flutter: New Project’ action
4. 输入 Project 名称 (如myapp), 然后按回车键(可能时间较长)
5. 指定放置项目的位置，然后按蓝色的确定按钮
6. 等待项目创建继续，并显示main.dart文件

上述命令创建一个Flutter项目，项目名为myapp，其中包含一个使用Material 组件的简单的演示应用程序。

在项目目录中，您的应用程序的代码位于 lib/main.dart.

运行应用程序

1. 确保在VS Code的右下角选择了目标设备
2. 按 F5 键或调用Debug>Start Debugging
3. 等待应用程序启动
