Flutter：酒吧失败

Flutter 项目向我显示警告'Packages get' has not been run以及建议的解决方案，

• 获取依赖项
• 升级依赖项
• Ignore

正如建议的Darky https://stackoverflow.com/users/8394265/darky，在这个answer https://stackoverflow.com/a/49056175/5638630继续“获取依赖项”

我尝试过，但它显示了一个错误：

酒吧失败

/SoftSources/Flutter/flutter/bin/flutter --no-color packages get
Running "flutter packages get" in catalog...
Incompatible version constraints on test:
- flutter_test 0.0.0 depends on version 0.12.30+3
- sample_catalog depends on version 0.12.30+4
pub get failed (1)
Process finished with exit code 1

错误表明项目版本（或其他）存在问题，应该在我的 flutter 项目中的哪里更改它？

For Flutter http://flutter.io项目运行

flutter packages get

代替

pub get packages
