The current Dart SDK version is 2.19.5.
Because pivot_chat requires SDK version >=3.0.0 <4.0.0, version solving failed.
pub get failed
command: "D:\Flutter\flutter\bin\cache\dart-sdk\bin\dart __deprecated_pub --directory . get --example"
pub env: {
"FLUTTER_ROOT": "D:\Flutter\flutter",

报错啦怎么办？
找到了我的电脑里面dart SDK的位置，D:\Flutter\flutter\bin\cache\dart-sdk
我认为是dart的版本不够的时候，我就去下载新的dart SDK（下载地址：Archive | Dart
），然后去替换我之前的dart-sdk，然后就出现问题了，官方的flutter sdk中已经自带了匹配版本的dart sdk。所以不要自己手动去替换。不要自己手动去替换。不要自己手动去替换。
所以后来我就去想着下载一个新的flutter sdk（下载地址：Flutter SDK 版本列表 - Flutter 中文文档 - Flutter 中文开发者网站 - Flutter），我就把我下载的flutter sdk给替换之前的，然后，然后就点击 Pub get，就出现了
--no-color pub get Waiting for another flutter command to release the startup lock...这个怎么解决呢？
********* 进入flutter sdk 目录，然后找到bin/cache/lockfile文件，删除后,即可解决
然后再运行，又出现问题了（见下图）
Building with plugins requires symlink support.
Please enable Developer Mode in your system settings. Run
start ms-settings:developers
to open settings.后来查阅资料发现，如果是window11系统的话就要打开电脑的开发者选项(Click on Privacy & Security and after, click on for developers option.)
打开开发者 模式就行啦
