這里我們需要一個(gè)第三方庫(kù):

https://pub.dev/packages/flutter_swiper#-readme-tab-

一. 安裝方法:

1. 在根目錄pubspec.yaml文件中添加依賴

dependencies:
  flutter_swiper: ^1.1.6

2. 如果是VS,第二步是自動(dòng)執(zhí)行的

$ flutter pub get

3. 在想用的文件中導(dǎo)入:

import 'package:flutter_swiper/flutter_swiper.dart';

二. 輕松使用

這里總結(jié)了幾種樣式, 都很不錯(cuò),直接拿過(guò)來(lái)用就可以了

import 'package:flutter/material.dart';
import 'package:flutter_swiper/flutter_swiper.dart'; //引入這個(gè)控件

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  List<Image> imgs = [

                },
                itemCount: imgs.length,
                autoplay: true,
                pagination: new SwiperPagination(), //這些都是控件默認(rèn)寫好的,直接用

                  new Offset(-370.0, -40.0),
                  new Offset(0.0, 0.0),
                  new Offset(370.0, -40.0)

              ),
            ),
          ],
        ),
      ),
    );
  }
}

三. 常用參數(shù)

我們可以通過(guò)設(shè)置控件幫我們準(zhǔn)備好的屬性進(jìn)一步滿足我們的需求.
如果還不夠用, 還可以重寫這個(gè)控件.
