Flutter开发进阶：环境搭建

一、flutter安装与配置

1.下载macOS版本

• flutter地址：https://flutter.io/sdk-archive/#macos

2.配置flutter环境

#Flutter 镜像配置
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn 

#Flutter 配置Flutter命令行工具
export FLUTTER=~/Workspace/flutter
export PATH=~/Workspace/flutter/bin:$PATH

检测：

flutter doctor

二、安装安卓环境与配置

1.安装 Android Studio

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

2.配置安卓环境

export ANDROID_HOME=~/Workspace/android/SDK
export PATH=~/Workspace/android/SDK/tools:$PATH
export PATH=~/Workspace/android/SDK/platform-tools:$PATH

3.安装SDK

Android SDK, Android SDK Command-line Tools, and Android SDK Build-Tools:

• Android SDK Build-Tools 31
• Android SDK Platform-Tools
• Android SDK Tools(Obsolete)

4.安装 flutter + dart插件

• 略

三、问题解决

1.解决java bundle 找不到的问题

• 将应用 Android Studio.app 显示包内容中的 Contents/jre/Contents 内容拷贝到Contents/jre/jdk/Contents中。需要自己简历jdk目录。

2.解决flutter、dart未安装的问题：

• Flutter plugin not installed; this adds Flutter specific functionality.
• Dart plugin not installed; this adds Dart specific functionality.

给新目录添加软链接即可

ln -s ~/Library/Application\ Support/Google/AndroidStudio2021.1/plugins ~/Library/Application\ Support/AndroidStudio2021.1

3.HTTP hosthttps://maven.google.com/is not reachable

• 项⽬ --> Android -->build.gradle ⽂件，修改内容：找到buildscript 和allprojects 将⾥⾯的：

//google()
//mavenCentral()
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

• ⽂件路径：flutter/packages/flutter_tools/gradle/flutter.gradle，修改内容（加⼊阿⾥镜像）：

//google()
//mavenCentral()
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
