一、安装

1、下载flutter，解压

image.png

2、存放到指定位置

比如：/Users/xxxx/Flutter/flutter

执行命令

1、vim ~/.bash_profile
2、增加一行: export PATH=/Users/xxxx/Flutter/flutter/bin:$PATH
其中，/Users/xxxx/Flutter/flutter是flutter的路径，后面加/bin
3、保存一下，:wq
4、source ~/.bash_profile 更新生效一下

注意: 如果你使用的是zsh，终端启动时 ~/.bash_profile 将不会被加载，解决办法就是修改 ~/.zshrc ，在其中添加：source ~/.bash_profile

如果众所周知的原因，如果需要配置国内镜像——参考 使用镜像

3、检查安装效果 flutter doctor

执行 flutter doctor

第一次执行，可能会有问题，随之解决就好。

flutter doctor的执行示例

flutter doctor

按照提示，一个一个解决就是了

正常解决之后，会得到类似这样的结果：

 amqr@amqrMBP  ~   master ●✚  flutter doctor

二、Android Studio 安装Flutter

在没安装的Flutter插件之前，Languages & Frameworks 一栏是看不到Flutter和Dart的

image.png

在Settings的Plugins中，安装Flutter，就会把Dart也装上

image-1.png

安装之后，android studio 首页就会出现 Create Flutter Project 之类的字样了

卡在Craete Flutter项目怎么办

第一创建Flutter项目，可能会卡着不动。

解决办法：

• 1、如果有科学的上网方式，开启全局代理就好
• 2、如果没有，配置国内镜像地址 （bash_profile或者zshrc配置一下）

问题解决之后，就可以顺利进入如下界面

image-4.png

next即可。

第一个工程的创建比较久

创建好之后的界面

运行程序

andorid的运行，怼线直接运行，或者模拟器。

iOS的运行，模拟器是直接就可以的。

iOS真机运行 参考 安装到iOS设备
