Flutter 脚手架Cli安装及项目创建

第一步：安装Cli脚手架

我们通过命令flutter pub global activate get_cli 进行脚手架的全局安装，本文以Mac OS为例。

EternalUMacPro@EternalUniverse ~ % flutter pub global activate get_cli

Building package executables...
Built get_cli:get.
Installed executables get and getx.
Warning: Pub installs executables into $HOME/Documents/Flutter配置/flutter/.pub-cache/bin, which is not on your path.
You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):

  export PATH="$PATH":"$HOME/Documents/Flutter配置/flutter/.pub-cache/bin"

Activated get_cli 1.7.1.

第二步：设置环境变量

一般Mac的环境变量都是通过根目录的.bash_profile进行环境变量设置。

//终端打开配置文件
EternalUMacPro@EternalUniverse ~ %  open .bash_profile
//在打开的文件中添加路劲<这里看自己路径设置>
#GetX
export PATH="$PATH":"$HOME/Documents/Flutter配置/flutter/.pub-cache/bin"

第三步：使设置的环境变量生效

我们可以通过source 加上路径，对环境变量生效。

EternalUMacPro@EternalUniverse ~ % source "/Users/EternalUniverse/.bash_profile"

第四步：校验是否成功安装

我们通过get命令，看能不能打印如下，如果有，那么恭喜你安装成功了。

EternalUMacPro@EternalUniverse ~ % get

List available commands:

  create:  
    controller:  Generate controller
    page:  Use to generate pages
    project:  Use to generate new project
    provider:  Create a new Provider
    screen:  Generate new screen
    view:  Generate view
  generate:  
    locales:  Generate translation file from json files
    model:  generate Class model from json
  help:  Show this help
  init:  generate the chosen structure on an existing project:
  install:  Use to install a package in your project (dependencies):
  remove:  Use to remove a package in your project (dependencies):
  sort:  Sort imports and format dart files
  update:  To update GET_CLI
  --version:  Shows the current CLI version'

Time: 940 Milliseconds

Cli创建工程

我们可以通过get create project来进行创建工程，

EternalUMacPro@EternalUniverse desktop % get create project
?  (Use arrow keys)
