Flutter GetX系列教程---Cli使用以及常用命令
GetX Cli安装
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MacOS为例。
flutter pub global activate get_cli + _fe_analyzer_shared 61.0.0 (67.0.0 available) + analyzer 5.13.0 (6.4.1 available) + ansicolor 2.0.2 + archive 3.4.10 + args 2.4.2 + async 2.11.0 + basic_utils 5.5.4 (5.7.0 available) + boolean_selector 2.1.1 + characters 1.3.0 + charcode 1.3.1 + chunked_stream 1.4.2 + circular_buffer 0.11.0 + cli_util 0.4.1 + clock 1.1.1 + collection 1.18.0 + convert 3.1.1 + coverage 1.6.4 (1.7.2 available) + crypto 3.0.3 + csv 5.1.1 (6.0.0 available) + dart_console2 3.0.0 + dart_style 2.3.2 (2.3.6 available) + dcli 2.3.0 (3.3.6 available) + dcli_core 2.3.0 (3.3.6 available) + equatable 2.0.5 + ffi 2.1.2 + file 6.1.4 (7.0.0 available) + frontend_server_client 3.2.0 + functional_data 1.1.1 + get_cli 1.8.4 + glob 2.1.2 + globbing 1.0.0 + http 0.13.6 (1.2.1 available) + http_multi_server 3.2.1 + http_parser 4.0.2 + ini 2.1.0 + intl 0.18.1 (0.19.0 available) + io 1.0.4 + js 0.6.7 (0.7.1 available) + json2yaml 3.0.1 + json_annotation 4.8.1 + logging 1.2.0 + matcher 0.12.16+1 + meta 1.12.0 + mime 1.0.5 + node_preamble 2.0.2 + package_config 2.1.0 + path 1.9.0 + pointycastle 3.7.4 + pool 1.5.1 + posix 5.0.0 (6.0.1 available) + process_run 0.12.5+3 (0.14.2 available) + pub_semver 2.1.4 + pubspec 2.3.0 + pubspec2 2.4.2 (4.0.0 available) + pubspec_lock 3.0.2 + quiver 3.2.1 + random_string 2.3.1 + recase 4.1.0 + scope 3.0.0 (4.1.0 available) + settings_yaml 6.0.0 (8.0.1 available) + shelf 1.4.1 + shelf_packages_handler 3.0.2 + shelf_static 1.1.2 + shelf_web_socket 1.0.4 + source_map_stack_trace 2.1.1 + source_maps 0.10.12 + source_span 1.10.0 + stack_trace 1.11.1 + stream_channel 2.1.2 + string_scanner 1.2.0 + sum_types 0.3.5 + synchronized 3.1.0+1 + system_info2 4.0.0 + term_glyph 1.2.1 + test_api 0.6.1 (0.7.0 available) + test_core 0.5.9 (0.6.0 available) + typed_data 1.3.2 + uri 1.0.0 + uuid 3.0.7 (4.3.3 available) + validators2 5.0.0 + version 3.0.2 + vm_service 11.10.0 (14.1.0 available) + watcher 1.1.0 + web 0.5.1 + web_socket_channel 2.4.4 + webkit_inspection_protocol 1.2.1 + win32 4.1.4 (5.3.0 available) + yaml 3.1.2 Building package executables... (23.8s) Built get_cli:get. Installed executables get and getx. Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path. You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.): export PATH="$PATH":"$HOME/.pub-cache/bin" Activated get_cli 1.8.4.
第二步：设置环境变量
一般Mac的环境变量都是通过根目录的 code ~/.zshrc 进行环境变量设置。
#getX
export PATH="$PATH":"$HOME/.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。
source ~/.zshrc
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。
Cli创建工程
我们可以通过get create project来进行创建工程，
get create projectr
然后出现报错提示

解决方法：
flutter pub global activate --source=git https://github.com/inyong1/get_cli.git
然后出现如下提示，我们选择创建Flutter Project

如果能看到如上就证明通过Cli创建工程成功了。
Cli创建页面
第一种：Getx_pattern
cd getx_demo工程目录下, 我们可以通过get create page:login来快速创建一个页面，这个页面有controller、view、binding、routes等配置，结构是Getx_pattern
get create page:login
第二种：CLEAN
我们可以通过get create page:login来快速创建一个页面，这个页面有controller、view、binding、routes等配置，结构是CLEAN。
Cli创建控制器
我们可以通过get create controller:login来快速为已存在的page进行创建controller，并且他还重新了controller的生命周期以及初始化方法。
get create controller:another on home
Cli创建View
如果我们只是想单独创建一个View，那我们可以通过get create view:alogin on login来进行创建。
get create view:alogin on login
Cli创建Provider
如果我们需要创建GetConnect，那我们可以通过get create provider:blogin on login来进行创建。
get create provider:blogin on login
Cli创建国际化
如果我们需要对应用进行国际化配置，那我们可以通过get generate locales assets/locales来进行创建。
get generate locales assets/locales
Cli通过json生成模型
第一种：不仅创建模型类，还会提供Provider
如果我们需要对某个json文件生成模型，那我们可以通过get generate model on home with assets/models/user.json来进行生成
get generate model on home with assets/models/user.json
第二种：只生成模型类
get generate model on login with assets/models/user.json --skipProvider
第三种：通过连接生成模型类
get generate model on home from "https://api.github.com/users/CpdnCristiano"
Cli安装包（dependencies)
第一种：直接安装最新版本
get install dio
第二种：同时安装多个包
get install path dio
第三种：安装自定版本的包
get install prodiver:5.0.0
Cli安装包（dev_dependencies)
我们可以通过get install flutter_launcher_icons --dev安装开发时所依赖的包
get install flutter_launcher_icons --dev
Cli卸载包
第一种：卸载某个安装包
get remove http
第二种：同时卸载多个包
get remove dio path
Cli更新脚手架
我们可以通过get update对脚手架进行更新
get update
Cli查看版本号
我们可以通过get -v 查看当前脚手架的版本号
get -v
Cli帮助
当我们忘记了命令的使用方式，我们可以通过get help进行查看帮助。
get help
总结
以上就是对Cli的脚手架命令的一个实践和总结，相对于自己手动创建结构，用Cli就可以很轻松的实现。
