1，关于 flutter

使用Android Studio 做开发，还好这个几个工具都有国内的镜像了。

Studio 从这里下载：

https://developer.android.google.cn/studio

速度超级快，解决了不少问题。

flutter 从这里下载也是国内镜像地址：

https://flutter.cn/docs/get-started/install

2，使用

配置 Android SDK 环境，还好这个网络速度快。
在这里插入图片描述

打开bios 的虚拟化技术。
主板不一样其BISO中显示关键词也不一样的，主要是找到Virtual或Virtualization将其设置为Enabled。

然后就可以使用 Android SDK 的 X86 镜像了。这个是速度比 ARM 的镜像快。

配置环境变量：

export PATH="$PATH:/media/test/NewDisk1/opt/flutter/bin"
export ANDROID_HOME="/media/test/NewDisk1/opt/android-sdk"
# add from https://flutter.cn/
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PUB_HOSTED_URL=https://pub.flutter-io.cn

使用flutter doctor 可以检查flutter 环境状况：

 flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.12.13+hotfix.7, on Linux, locale zh_CN.UTF-8)
[✗] Android toolchain - develop for Android devices✗ Unable to locate Android SDK.Install Android Studio from: https://developer.android.com/studio/index.htmlOn first launch it will assist you in installing the Android SDK components.(or visit https://flutter.dev/setup/#android-setup for detailed instructions).If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location.You may also want to add it to your PATH environment variable.[!] Android Studio (version 3.5)✗ Flutter plugin not installed; this adds Flutter specific functionality.✗ Dart plugin not installed; this adds Dart specific functionality.

Android Studio 安装插件：

有的时候会网络环境不好，多尝试几次，或者晚上早晨人少的时候再实验。

都弄好了，再使用 flutter doctor 命令：

$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.12.13+hotfix.7, on Linux, locale zh_CN.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
[✓] Android Studio (version 3.5)
[!] IntelliJ IDEA Community Edition (version 2019.3)✗ Flutter plugin not installed; this adds Flutter specific functionality.✗ Dart plugin not installed; this adds Dart specific functionality.
[!] Connected device! No devices available! Doctor found issues in 2 categories.

这样就说明所有的环境和IDE 工具都可以了。
