Mac系统下Flutter安装教程

一、下载Flutter

1、第一种方式git repo方式:

执行下列命令下载最新的flutter代码(系统请先安装Git)

git clone -b beta https://github.com/flutter/flutter.git

2、第二种方式Flutter官网下载:

https://docs.flutter.dev/development/tools/sdk/releases?tab=macos

二、安装:android Studio

下载地址:https://developer.android.google.cn/studio

三、安装Xcode,直接前往App Store下载安装即可。

四、安装flutter,环境配置,依赖项检查

1、永久的将flutter添加到path中:

1.1、在用户文件夹下找到.bash_profile文件,如果没有就创建一个(如果有 1.1.1此步骤忽略);

 1.1.1、.bash_profile文件创建方法如下:

   (1)终端执行:touch .bash_profile

   (2)打开文件:open .bash_profile

   (3)更新配置,文件才能生效:source .bash_profile

1.2、将下面三个export拷贝到.bash_profile文件中:

    **export** PUB_HOSTED_URL=https://pub.flutter-io.cn

    **export** FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

    **export** PATH=/Users/chengxinsong/Desktop/Tool/flutter/bin:$PATH

    // 备注:chengxinsong是你电脑的名称(记得替换);/Users/chengxinsong/Desktop/Tool/是Flutter的安装路径

1.3、添加保存后,执行下列命令刷新终端:

    source $HOME/.bash_profile

1.4、如果你的系统使用的是zsh(即终端最顶部显示的-zsh),却用了.bash_profile文件,终端启动时.bash_profile文件 将不会被加载,

  解决办法就是修改 .zshrc文件(终端打开方式:open ~/.zshrc) ,在其中添加:source ~/.bash_profile

1.5、运行下列命令检查flutter是否已经安装成功:

    flutter -v

1.6、检查flutter的依赖项命令

    flutter doctor

1.7、前边所有步骤均没问题话,运行flutter doctor后会出现如下输出:

1.7.1、如果出现:Flutter 环境配置提示 cmdline-tools component is missing

    解决办法:启动 android studio工具

            -> 在一开始打开的右下角找到Configure

            -> 进入SDK Manager

            -> 取消右下角的 Hide Obselete Packages的勾选

            -> 选择SDK Tools,在这里把缺少的tool勾选上一并安装上

1.7.2、如果出现:Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses

   解决办法:终端直接输入 flutter doctor --android-licenses

1.7.3、如果以上均没有问题后,则只需根据终端的提示输入 y 即可

1.7.4、以上步骤都走完后:检测Flutter的安装情况:flutter doctor

1.7.5、如果以上均没有问题会有如下输出:

mr.lv@MrlvdeMacBook-Pro ~ % flutter doctor

2、如果习惯使用VSCode开发Flutter的话,需要再安装VSCode工具

下载地址:https://code.visualstudio.com/ 【此安装包会自动弹出汉化安装】

      或者:https://code.visualstudio.com/download

2.1、Dart官网:https://dart.dev/

2.2、Dart环境官方文档:https://dart.dev/get-dart

2.3、安装 Homebrew 检测是否安装brew,执行命令 brew -v,

    如果安装了,就执行 2.4,

    如果没安装先安装:https://brew.sh

    即:将 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

    复制到终端执行。

2.4、Dart SDK 安装: 打开终端 依次执行:

        brew tap dart-lang/dart

        brew install dart

        brew info dart

        输出:==> Caveats

                 Please note the path to the Dart SDK:

                 /usr/local/opt/dart/libexec

备注:dart sdk安装亦可参照此文:https://www.cnblogs.com/strengthen/p/16305014.html

2.5、在VSCode安装 Dart 插件(dart语言提示)

2.6、安装 code runner 插件(可以运行我们的文件)

2.7、安装 Code Spell Checker 插件(拼写检查)

2.7、检测 Dart插件情况:

     在终端上输入 dart --version 命令来检测dart是否安装成功,如果出现如下内容则安装成功:

     输出:Dart SDK version: 2.18.4 (stable) (Tue Nov 1 15:15:07 2022 +0000) on "macos_x64"

            则代表安装成功。

到此,就可以用Dart语言正常进行开发了!
