指南就不写了，所有 Flutter 项目都差不多，也没什么特别值得写的

好像我导入另外一个项目也会报同样的错误，不是web项目， 可能什么地方配置不对， 第一次搞flutter 😄 |

运行错项目了， “使用Dart Command Line App去运行了” 导致找不到dart:ui 但是在运行到模拟器的时候又报了另外一个错误，看起来是又重复引用， 是不是还是什么版本不对呢： [√] Flutter (Channel stable, 3.10.2, on Microsoft Windows [版本 10.0.19045.2965], locale zh-CN) Dart SDK version: 3.0.2 (stable) (Tue May 23 08:26:58 2023 +0000) on "windows_x64" Launching lib\main.dart on sdk gphone x86 64 in debug mode... FAILURE: Build failed with an exception.

你好，搭建了半天环境 😄, 请问可以写一个详细的运行起来的指南作为新手的指导吗？
安装了flutter \IDEA \Android Stuio ,IDAE 上边配置好了DART， flutter packages get
出现错误提示说Itnl版本是0.17.0 ，我给改成我当前环境的0.18.0 了， 然后get 没有报错。 最后跑下边的测试，出现错误， 请问是哪儿的问题
