我没有使用GIT。正如我所看到的一些帖子/问题，用户提到他们正在使用GIT，并且由于这些错误而导致问题。
昨天，我添加了Image Cropper插件，然后重新启动了计算机。重新启动后，它开始显示错误。
The current Flutter SDK version is 0.0.0-unknown.
Because image_cropper 1.2.1 requires Flutter SDK version ^1.12.13 and no versions of image_cropper match >1.2.1 <2.0.0, image_cropper ^1.2.1 is forbidden.
So, because demoapp depends on image_cropper ^1.2.1, version solving failed.
pub get failed (1; So, because demoapp depends on image_cropper ^1.2.1, version solving failed.)

我运行Flutter版本命令->下面是输出。
Flutter 1.12.13+hotfix.9 • channel stable • https://github.com/flutter/flutter.git
Framework • revision f139b11009 (6 weeks ago) • 2020-03-30 13:57:30 -0700
Engine • revision af51afceb8
Tools • Dart 2.7.2
我做了Flutter Clean和Flutter Pub，让他们俩都没有解决问题。
我运行Flutter Doctor，这是输出。

我从一开始就没有使用Xcode。
有关如何解决此问题的任何建议。
编辑
我通过运行echo $ PATH检查了路径。
/Users/rahul/Desktop/flutter/bin
路径也在那里。
编辑2 Flutter Upgrade也没有帮助。
