我没有使用GIT。因为我看到一些帖子的问题，用户提到他们使用GIT，由于他们得到的错误。
昨天，我添加了图像裁剪插件，然后我重新启动了机器。重启后，它开始给出错误。
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。

我做了Flutter Clean和Flutter Pub Get他们都没有解决这个问题。

任何关于如何解决这个问题的建议。
编辑
我通过运行echo $PATH来检查路径。
/Users/rahul/Desktop/flutter/bin
路径也在那里。
编辑2翩翩升级也没有用。
