轮播图在app中必不可少，最近笔者也在做app，以下是一个简单的flutter实现banner轮播图方法，提供给大家参考。

1、安装轮播组件

打开pubspec.yaml文件

将flutter_swiper: ^1.1.4插件添加到pubspec.yaml里面

2、实现代码：

import 'package:flutter/material.dart';
import 'package:flutter_swiper/flutter_swiper.dart';
class HomePage extends StatefulWidget{
  @override
  _HomePageState createState()=>_HomePageState();
}
class _HomePageState extends State<HomePage>{
  List _imageUrls=[
    'https://img1.doubanio.com/view/photo/l/public/p2566812248.webp',
    'https://img3.doubanio.com/view/photo/l/public/p2607105432.webp',

  ];
  @override
  Widget build(BuildContext context){
      return Scaffold(
        body:Center(
          child: Column(
            children: <Widget>[
              Container(
                height: 200,
                child: Swiper(
                  itemCount: _imageUrls.length,
                  autoplay: true,
                  itemBuilder: (BuildContext context,int index){
                    return Image.network(
                      _imageUrls[index],
                      fit:BoxFit.fill,
                    );
                  },
                  pagination: SwiperPagination(),
                ),
              ),
            ],
          ),
        ),
      );
  }
}

3、效果图
