【问题描述】:
我是使用颤振的新手,我已经被上述错误卡住了一个多星期。我在这个论坛上搜索了可能的解决方案,但没有找到。这是下面的代码,请协助更正/建议。提前致谢:

class AfterSplash extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new Scaffold( <=1 required argument(s) expected, but 0 found. on the open bracket sign
appBar: new AppBar(

),
backgroundColor: Colors.black38,
body:
new ImageCarousel(
<ImageProvider>[
new NetworkImage(

new NetworkImage(

new NetworkImage(

],

bottomNavigationBar: new BottomNavigationBar(

new BottomNavigationBarItem(

是的@daniel,我正在使用 dart2,但在使用图像轮播之前运行 carousel pro 包时遇到了同样的问题。即使我完全删除轮播包,同样的错误仍然存在
