flutter 进阶 GetX系列教程---Cli使用以及常用命令

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。

fanhudeMacBook-Pro:~ jm$ flutter pub global activate get_cli

Precompiling executables...
Precompiled get_cli:get.
Installed executables get and getx.
Warning: Pub installs executables into $HOME/Flutter_Mac/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/Flutter_Mac/flutter/.pub-cache/bin"

Activated get_cli 1.6.0.

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。

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

1. 在命令行中输入：

export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/X11R6/bin

这样可以保证命令行命令暂时可以使用。命令执行完之后先不要关闭终端。
如果你的命令行命令可以使用，请直接跳到第2步。

2. 进入当前用户的home目录：

cd ~/

3. 创建.bash_profile文件：

touch .bash_profile

4. 打开.bash_profile并编辑：

open .bash_profile

第三步：使设置的环境变量生效

JMdeMacBook-Pro:~ jm$ source "/Users/jm/.bash_profile"

第四步：校验是否成功安装

检查是否安装成功

JMdeMacBook-Pro:~ jm$ 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

  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'

Cli创建工程

我们可以通过get create project来进行创建工程，

JMdeMacBook-Pro:getx jm$ get create project

然后出现如下提示，我们选择创建Flutter Project

-->   1) Flutter Project
      2) Get Server

选择之后需要输入工程名称、公司域名、选择iOS语言、选择Android语言、是否空安全、是否校验，选完知道就会为我们开始创建工程。

JMdeMacBook-Pro:getx jm$ get create project
-->   1) Flutter Project
      2) Get Server
? what is the name of the project? getx_example
? What is your company's domain?  Example: com.yourcompany  com.jimi

what language do you want to use on ios?

      1) Swift
-->   2) Objective-C

what language do you want to use on android?

      1) Kotlin
-->   2) Java

Do you want to use null safe?

-->   1) Yes!
      2) No

do you want to use some linter?

      1) no
      2) Pedantic [Deprecated]
      3) Effective Dart [Deprecated]
-->   4) Dart Recommended

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
✓  File: another_controller.dart created successfully at path: ./lib/app/modules/home/controllers/another_controller.dart
✓  The Another has been added to binding at path: lib/app/modules/home/bindings/home_binding.dart'

Time: 387 Milliseconds

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 
✓  File: alogin_view.dart created successfully at path: ./lib/app/modules/login/views/alogin_view.dart

Time: 378 Milliseconds

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。

JMdeMacBook-Pro:getx_example jm$ get create provider:blogin on login
✓  File: blogin_provider.dart created successfully at path: ./lib/app/modules/login/providers/blogin_provider.dart

✓  File: locales.g.dart created successfully at path: lib/generated/locales.g.dart
✓  locale files generated successfully.

Time: 416 Milliseconds

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

JMdeMacBook-Pro:getx_example jm$ get generate model on home with assets/models/user.json
✓  File: user_model.dart created successfully at path: ./lib/app/modules/home/user_model.dart
✓  File: user_provider.dart created successfully at path: ./lib/app/modules/home/providers/user_provider.dart

Time: 499 Milliseconds

第二种：只生成模型类

JMdeMacBook-Pro:getx_example jm$ get generate model on login with assets/models/user.json --skipProvider
✓  File: user_model.dart created successfully at path: ./lib/app/modules/login/user_model.dart

Time: 408 Milliseconds

第三种：通过连接生成模型类

JMdeMacBook-Pro:getx_example jm$ get generate model on home from "https://api.github.com/users/CpdnCristiano"
? Could not set the model name automatically, which name do you want to use? githubHome
✓  File: github_home_model.dart created successfully at path: ./lib/app/modules/home/github_home_model.dart
✓  File: github_home_provider.dart created successfully at path: ./lib/app/modules/home/providers/github_home_provider.dart

Time: 14033 Milliseconds

Cli安装包（dependencies)

第一种：直接安装最新版本

JMdeMacBook-Pro:getx_example jm$ get install dio

Installing package "dio" …

✓  'Package: dio installed!

Running `flutter pub get` …

$ flutter pub get
Running "flutter pub get" in getx_example...                     2,656ms

Time: 5815 Milliseconds

第二种：同时安装多个包

JMdeMacBook-Pro:getx_example jm$ get install path dio

Installing package "path" …

✓  'Package: path installed!

第三种：安装自定版本的包

JMdeMacBook-Pro:getx_example jm$ get install prodiver:5.0.0

Installing package "prodiver" …

✓  'Package: prodiver installed!

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

JMdeMacBook-Pro:getx_example jm$ get install flutter_launcher_icons --dev


The [--dev] is not necessary


Installing package "flutter_launcher_icons" …

✓  'Package: flutter_launcher_icons installed!

Cli卸载包

第一种：卸载某个安装包

JMdeMacBook-Pro:getx_example jm$ get remove http

Removing package: "http"
