1.按照官方文档的安装dart语言

Install using a Linux package manager

#

You have two options to install the Dart SDK on Ubuntu or Debian:

• Use the apt-get command.
• Download a .deb package and run the dpkg command.

Install using the apt-get package manager

#

To install Dart with apt-get, perform the following steps. You need steps 1 to 3 only for the first install.

1. Update the package index files and install the secure HTTP package.

   $ sudo apt-get update && sudo apt-get install apt-transport-https

2. Download and add the Google Linux GPG public key.

   $ wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub \| sudo gpg  --dearmor -o /usr/share/keyrings/dart.gpg

   content_copy

3. Add the Dart package repository to your Linux system.

   $ echo 'deb [signed-by=/usr/share/keyrings/dart.gpg arch=amd64] https://storage.googleapis.com/download.dartlang.org/linux/debian stable main' \| sudo tee /etc/apt/sources.list.d/dart_stable.list

   content_copy

4. Use the following sudo apt-get commands.

   $ sudo apt-get update && sudo apt-get install dart

dart --version 可以看到dart安装的版本 dart sdk 存储路径在/user/lib/dart

二、下载 https://dart.dev/get-dart flutter sdk 解压下 比如放在这个目录下/home/denghg/Flutter/flutter

三、添加flutter 到linux的环境变量下 这里有个坑flutter的环境变量得在系统PATH的前面

export FLUTTER_PATH=/home/denghg/Flutter/flutter/bin
export PATH=$FLUTTER_PATH:$PATH:$JAVA_HOME:$ANDROID_NDK:$ANDROID_SDK:$ANDROID_HOME:$CMAKE_PATH:$DEPOT_TOOL:$NODE_PATH:$GOROOT:$GOPATH:$NGINX:$GOPROXY:$FFMPEG_PATH:$SVG_PATH:$SHELL_PATH

flutter sdk 跟dartsdk是两个不同的东西 dart 是一份语言sdk flutter是一个框架调用dart语言所以两个都要。

四、 android studio plugin 安装Flutter插件 然后配置Flutter sdk位置

然后运行flutter doctor验证环境配置 根据提示的问题修改

比如缺少android command-line tools
