(有一个隐藏的文字捕捉手势)

(尝试devTools来找到它)

opened devTools > clicked on device screen after devTools opened > clicked search button on the bottom left of the screen > clicked the portoin of the screen that wasn't catching the gestures > damn widget showed on devtool's WidgetTree :D

(打开devTools>在打开devTools之后在设备屏幕上单击>单击屏幕左下角的搜索按钮>单击屏幕上未捕获手势的portoin> devtool的WidgetTree上显示的该死的小部件：D)
