这是我在应用程序中添加轮播滑块的代码

homescreen.dart

import 'package:eat_healthy/caroslider.dart';
import 'package:flutter/material.dart';
import 'package:gradient_app_bar/gradient_app_bar.dart';
import 'package:share/share.dart';
import 'package:eat_healthy/drawer.dart';
import 'package:dynamic_theme/dynamic_theme.dart';
import 'package:dynamic_theme/theme_switcher_widgets.dart';





class HomeScreen extends StatefulWidget {
  HomeScreen({Key key, this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: GradientAppBar(
        gradient: LinearGradient(
            colors: [Colors.deepPurple, Colors.deepPurpleAccent, Colors.purple]),
        actions: <Widget>[
          IconButton(
              icon: Icon(
                Icons.share,
                color: Colors.white,
              ),
              onPressed: () {
                Share.share('Installl this app to know about health benefits of apple ');
              })
        ],
      ),
      drawer: AppDrawer(),
      body: Stack(
        fit: StackFit.expand,
        children: <Widget>[

 CaroSlider() 

        ],
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: showChooser,
        child: const Icon(Icons.add),
      ),);

  }

  void showChooser() {
    showDialog<void>(
        context: context,
        builder: (context) {
          return BrightnessSwitcherDialog(
            onSelectedTheme: (brightness) {
              DynamicTheme.of(context).setBrightness(brightness);
            },
          );
        });
  }


}

Caroslider.dart

import 'package:carousel_pro/carousel_pro.dart';
import 'package:flutter/material.dart';




final myCarousel = Carousel(
  dotSize: 5.0,
  dotIncreaseSize: 2.0,
  borderRadius: true,
  radius: Radius.circular(10.0),
  animationCurve: Curves.easeInOut,
  animationDuration: Duration(seconds: 2),

  ],
);








class CaroSlider extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Padding(
        padding: EdgeInsets.symmetric(vertical: 15.0),
        child:myCarousel
        );
  }
}

Caroslider 代码有什么问题。

I/flutter (3766)：以下断言被抛出构建轮播（脏，状态：CarouselState#7c7de）：I/flutter（3766）：类型 'String' 不是 'Widget' I/flutter 类型的子类型（3766）： I/flutter (3766): 任何一个断言都表示在框架本身，或者我们应该提供大量的 I/flutter ( 3766）：此错误消息中的更多信息可帮助您确定并解决根本原因。
