Flutter packages get 不安装新包

Question

我正在尝试在 flutter 中安装一个包(dynamic_theme)。当我运行 flutter packages get -v 时，它甚至不会尝试安装该包。

到目前为止我已经尝试过:

• 运行flutter packages get
• 运行flutter packages get
• 重新启动计算机
• 更新了 flutter
• 添加了另一个软件包，但没有安装
• 更新了 Android Studio

在我的 pubspec.yaml 中我放入了:

dependencies:
  flutter:
    sdk: flutter
  firebase_core:
  cupertino_icons: ^0.1.2
  dynamic_theme: ^1.0.1 # the package does not install
  uuid: 2.0.0 # the package does not install

在 flutter packages get 详细运行的日志中，它安装了输出的包:

[ +422 ms] Running "flutter packages get" in quiz_app... (completed in 0.4s)
[  +57 ms] Found plugin firebase_core at E:\Other\SDKs\flutter\.pub-cache\hosted\pub.dartlang.org\firebase_core-0.3.4\

[  +26 ms] "flutter get" took 718ms.

我预计 flutter 下载并安装了这些软件包，但它只是检查已安装的软件包的更新，例如 firebase_core .
