| Navigator.pushNamed(context, CameraPage.routeName,
arguments: CameraPageArguments(
param: '参数',

注意
如果需要回传数据
1
| await Navigator.pushNamed(context,CameraPage.routeName)
|
可能报错：
type ‘MaterialPageRoute‘ is not a subtype of type ‘Route‘ in type cast
可以改为使用：
1
| await Navigator.of(context).pushNamed(CameraPage.routeName);
