我试图将我的menuButton类别名称传递给下一页,并在我的categoryScreens上设置下一页的状态。
当前,我收到一条红色的波浪线,并带有“不能将参数类型'Context'分配给参数类型'BuildContext'的注释”
import 'package:flutter/material.dart';
import 'package:boardwalk/Screens/categoryScreen.dart';
import 'package:boardwalk/Widgets/headerCategory.dart';
import 'package:path/path.dart';
class homeMenu extends StatelessWidget {
const homeMenu({Key key}) : super(key: key);
Padding menuButton(String category, IconData categoryIcon) {
return Padding(
padding: const EdgeInsets.symmetric(horizontal: 10),
child: Container(
width: 95,
child: InkWell(
onTap: ()=>
Navigator.of(context).push(MaterialPageRoute(builder: (context) => categoryScreen()));
,
child: Column(
children: <Widget>[
Center(
child: Container(
height: 70,
width: 70,
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.deepPurple, Colors.deepPurpleAccent],
),
shape: BoxShape.circle,
),
child: Icon(
categoryIcon,
size: 40.0,
color: Colors.white,
),
),
),
Padding(
padding: const EdgeInsets.all(6.0),
child: Text(
category,
style: TextStyle(
color: Colors.deepPurpleAccent,
fontSize: 14,
),
),
)
],
),
),
));
}
@override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.only(top: 8.0),
child: Container(
height: 100,
width: 400,
child: ListView(scrollDirection: Axis.horizontal, children: <Widget>[
menuButton('Home', Icons.home),
menuButton('Eat', Icons.restaurant_menu),
menuButton('Shop', Icons.store),
menuButton('Travel', Icons.airplanemode_active),
menuButton('Play', Icons.local_activity),
menuButton('Service', Icons.build),
]),
),
);
}
}
我不确定在导航器中传递的内容是否与上下文无关,我不确定在这一点上会发生什么。
最佳答案
实际上,此问题是由导入path.dart包引起的。要解决此问题,请将上下文更改为this.context
