flutter - 运行flutter pug bet时SDK相关的错误

Question

错误是这样的：

The current Dart SDK version is 2.14.0-301.2.beta.

Because observable ^0.22.1+4 depends on dart_internal >=0.1.1 <0.2.1 which requires SDK version >=2.0.0-dev.12.0 <2.13.0, observable ^0.22.1+4 is forbidden.
So, because arrazo depends on observable ^0.22.2, version solving failed.
Running "flutter pub get" in project...
pub get failed (1; So, because arrazo depends on observable ^0.22.2, version solving failed.)

我不知道如何解决这个错误，也不知道它的含义，你能帮我吗？
