重启电脑之后，再次运行就没问题了，暂不清楚问题出在哪里

example项目可以跑起来了，但是首页的菜单展不开，点击展开会报错：flutter: Another exception was thrown: 'package:dropdown_menu/_src/dropdown_menu.dart': error: line 272 pos 16: file:///Users/xxx/Desktop/FlutterDemo/flutter_dropdown_menu-master/lib/_src/dropdown_menu.dart:272:16: Error: A value of type '#lib1::TickerFuture' can't be assigned to a variable of type 'dart.async::Future'.

Hi,使用Flutter Dev 0.10.1有这个问题，Beta 0.9.4没有出现问题

现在beta可以升到 0.10.2了，以前的版本是没问题的，我刚升完版本就出你上面的bug了

大佬，更新一下版本呗，升了0.10.2用不了了，不弹出来
