GetX Cli安裝

第一步：安裝Cli腳手架

我們透過命令flutter pub global activate get_cli 進行腳手架的全域性安裝，本文以MacOS為例。

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：設定環境變數

一般Mac的環境變數都是透過根目錄的 code ~/.zshrc 進行環境變數設定。

#getX
export PATH="$PATH":"$HOME/.pub-cache/bin"

第三步：使設定的環境變數生效

我們可以透過source 加上路徑，對環境變數生效。

source ~/.zshrc

第四步：校驗是否成功安裝

我們透過get命令，看能不能列印如下，如果有，那麼恭喜你安裝成功了。

Cli建立工程

我們可以透過get create project來進行建立工程，

get create projectr

然後出現報錯提示

  2) Get Server

解決方法：

flutter pub global activate  --source=git https://github.com/inyong1/get_cli.git

然後出現如下提示，我們選擇建立Flutter Project

如果能看到如上就證明透過Cli建立工程成功了。

Cli建立頁面

第一種：Getx_pattern

cd getx_demo工程目錄下, 我們可以透過get create page:login來快速建立一個頁面，這個頁面有controller、view、binding、routes等配置，結構是Getx_pattern

get create page:login

第二種：CLEAN

我們可以透過get create page:login來快速建立一個頁面，這個頁面有controller、view、binding、routes等配置，結構是CLEAN。

Cli建立控制器

我們可以透過get create controller:login來快速為已存在的page進行建立controller，並且他還重新了controller的生命週期以及初始化方法。

get create controller:another on home　

Cli建立View

如果我們只是想單獨建立一個View，那我們可以透過get create view:alogin on login來進行建立。

get create view:alogin on login

　　

Cli建立Provider

如果我們需要建立GetConnect，那我們可以透過get create provider:blogin on login來進行建立。

get create provider:blogin on login　　

Cli建立國際化

如果我們需要對應用進行國際化配置，那我們可以透過get generate locales assets/locales來進行建立。

get generate locales assets/locales

Cli透過json生成模型

第一種：不僅建立模型類，還會提供Provider

如果我們需要對某個json檔案生成模型，那我們可以透過get generate model on home with assets/models/user.json來進行生成

get generate model on home with assets/models/user.json　　

第二種：只生成模型類

get generate model on login with assets/models/user.json --skipProvider

　　

第三種：透過連線生成模型類

get generate model on home from "https://api.github.com/users/CpdnCristiano"

　　

Cli安裝包（dependencies)

第一種：直接安裝最新版本

get install dio

　　

第二種：同時安裝多個包

get install path dio

　　

第三種：安裝自定版本的包

get install prodiver:5.0.0

　　

Cli安裝包（dev_dependencies)

我們可以透過get install flutter_launcher_icons --dev安裝開發時所依賴的包

get install flutter_launcher_icons --dev

　　

Cli解除安裝包

第一種：解除安裝某個安裝包

get remove http

　　

第二種：同時解除安裝多個包

get remove dio path

　　

Cli更新腳手架

我們可以透過get update對腳手架進行更新

get update

　　

Cli檢視版本號

我們可以透過get -v 檢視當前腳手架的版本號

get -v

　　

Cli幫助

當我們忘記了命令的使用方式，我們可以透過get help進行檢視幫助。

get help

　　

總結

以上就是對Cli的腳手架命令的一個實踐和總結，相對於自己手動建立結構，用Cli就可以很輕鬆的實現。
