java.lang.NullPointerException：尝试调用虚拟方法“ float android.view.InputDevice $MotionRange.getMin()”

概述每次单击窗口小部件时,我都会收到以下错误：java.lang.NullPointerException: Attempt to invoke virtual method 'float android.view.InputDevice$MotionRange.getMin()' on a null object reference 我转到另一个项目并收到相同

每次单击窗口小部件时,我都会收到以下错误：

java.lang.NullPointerException: Attempt to invoke virtual method 'float androID.vIEw.inputDevice$MotionRange.getMin()' on a null object reference

我转到另一个项目并收到相同的错误,该错误发生在TextFIEld,按钮和GrIDList项中.

我认为这可能是SDK中的错误

Flutter: 1.2.1Dart: 2.2.0

我升级了颤振,现在就收到了.

新细节：
我可以看到使用镜子(Vysor或Scrcpy)时会发生错误,当我用手指使用真实手机时,我只能使用该应用程序.最佳答案当我们使用应用程序在PC上进行镜像时,这是一个Flutter的错误,只需要更新Flutter,我使用的是1.3.8,就可以正常工作. 总结
