在 ubuntu 22.04 通过 snap 安装了 Flutter SDK（当前是Flutter 3.3.4)，如果第三方的依赖了 CMake 3.10.2 更高的版本，会在编译的时候报错：

CMake 3.14 or higher is required. You are running version 3.10.2

1	CMake 3.14 or higher is required. You are running version 3.10.2

这个报错的原因是由于 snap 安装的 Flutter SDK 构建了一个沙箱环境，在这个环境中的 CMake 是 3.10.2 版本，不管系统安装的是哪个版本的 CMake ，都是无效的。

要解决这个问题，或者等待 snap 的 Flutter SDK 更新版本，或者参照 Linux install Flutter 的说明，手工安装并配置 Flutter SDK 。

可以参考如下代码：

$ sudo snap remove flutter

$ sudo apt-get install curl

$ sudo apt-get install clang

$ sudo apt-get install git

$ sudo apt-get install ninja-build

$ sudo apt-get install pkg-config

$ sudo apt install gettext

$ sudo apt-get install libgtk-3-dev

$ sudo apt install libstdc++-12-dev

$ git clone https://github.com/flutter/flutter.git -b stable

$ export PATH="$PATH:`pwd`/flutter/bin"

$ cd `pwd`/flutter/bin 

$ ./flutter doctor

$ sudo snap remove flutter

$ sudo apt-get install curl

$ sudo apt-get install clang

$ sudo apt-get install git

$ sudo apt-get install ninja-build

$ sudo apt-get install pkg-config

$ sudo apt install gettext

$ sudo apt-get install libgtk-3-dev

$ sudo apt install libstdc++-12-dev

$ git clone https://github.com/flutter/flutter.git -b stable

$ export PATH="$PATH:`pwd`/flutter/bin"

$ cd `pwd`/flutter/bin

$ ./flutter doctor
