@slhaos ，兄弟，你这个发生在哪个手机，哪个系统版本上？demo上的例子跑的有问题吗？ |
|
@slhaos 你这个问题出现的有点奇怪，你可以先执行下flutter clean，将工程clean下，再运行试试，再解决不了的话，可以提供下手机型号和系统版本号，还好都是中国人，好交流，太困了，我先睡了 |
|
我就是在demo 在华为荣耀8 |
|
flutter clean 很多次了 |
|
@Slhaos7373 有qq吧，加我qq，1210514049， qq上可以发截图，录屏之类的，方便交流 |
|
不好意思 这两天重装了一下环境，有空吗 |
|
所以这个问题最终是解决了吗？ |
