MacBook M1 Flutter环境搭建的实现步骤

本文主要介绍了MacBook M1 Flutter环境搭建，Flutter官方和各项配套的软件环境也还没有成熟，导致搭建环境时碰到了不少坑，本文就详细的介绍一下

最近入手了Apple M1，MacBook Air，由于之前未使用苹果系列产品，并且Flutter官方和各项配套的软件环境也还没有成熟，导致搭建环境时碰到了不少坑，这里总结记录一波，来看文档的同学，有不懂的地方直接发评论或者消息就好

一、基础环境搭建

 git：

我是装完homebrew，git就装好了，homebrew的安装方法按照这个来的：

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

但是后面发现这个安装方法会有一些问题，不过不影响我们使用Flutter，不放心的同学可以去找其他方法安装git 

Flutter SDK：

国内的网络环境下，先配置两个环境变量，最好是~/.zshrc和~/.bash_profile两个文件都配上，配完source一下

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

下载安装直接按照官方文档来：https://flutter.cn/docs/get-started/install/macos

执行命令 flutter precache 或者 flutter doctor时会报错，因为没有在命令行执行安装rosetta的命令，详细的错误信息可以去下面的github地址查看

还少了一步操作，我第一天的晚上就卡在这儿了，最后去github提了issue，得到了一位老哥的提点

https://github.com/flutter/flutter/issues/74511#issue-792217747

终端执行命令

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

随后再执行flutter命令正常，继续按着官方的安装文档走，环境变量一定要配，不然以后在终端无法直接使用flutter命令

CocoaPods：

Flutter官方文档给出的安装方式是命令行运行命令

sudo gem install cocoapods

但是这样后期跑带插件的ios应用，需要用到Cocoapods时就会报错

需要使用 Rosetta 方式运行终端执行命令才行

打开 访达 -> 应用程序 -> 实用工具 -> 终端 -> 右键 -> 显示简介 -> 选中使用 Rosetta 打开

然后重新启动终端，执行

sudo gem install cocoapods
sudo gem install ffi

二、安装IDE

我安装了IDEA，Xcode和AndroidStudio

IDEA：

个人习惯使用IDEA做开发，社区版即可，而且已经对M1版本做了适配（题外话，mac体验果然好，打开IDEA的速度简直起飞）

下载地址：https://www.jetbrains.com/idea/download/

安装这里说个笑话，因为没用过mac，安装都不会，后面才知道安装是点击安装文件之后在出现的界面里把程序拖到Applications里😭

使用IDEA开发Flutter需要安装Dart和Flutter插件

Xcode：

ios开发必备（即使你不用ta来写代码），我安装只是让ta用来配置各项环境，省心（工具界的工具人？），装完一定记得要运行一次

官方下载地址：appstore搜索安装即可，比较大，时间会长一点

安装完之后运行命令，做IOS开发的相关设置

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -runFirstLaunch
sudo xcodebuild -license

AndroidStudio：

官方下载地址：https://redirector.gvt1.com/edgedl/android/studio/install/4.1.2.0/android-studio-ide-201.7042882-mac.dmg

装这个只是为了让他把安卓的环境都准备好（又一个工具界的工具人），跟着安装步骤一直点就好了，不过M1芯片的现在还没法直接用AS附带的安卓模拟器，真机调试把，windows下用过AS的老哥应该都很熟了

使用AS开发Flutter需要安装Dart和Flutter插件

三、跑一个app试试

按照官方文档来就行，随便用一个第三方依赖包，可以检测出CocoaPods是否正常安装

这个是我之前自己在windows上写的一个小应用，只用了 shared_preferences这个包

运行flutter pub get获取依赖包

开启IOS模拟器，运行

最终效果：
