参考 dart3.0使用flutter_swiper报错记录

flutter_swiper package - All Versions从官网的信息可以看到 Dart3版本不兼容 最小兼容的Dart SDK版本需要2.0

Flutter SDK 版本列表Flutter SDK 版本列表 - Flutter 中文文档 - Flutter 中文开发者网站 - Flutter

说明：因为flutter_swiper不兼容dart版本3.0 所以我们使用flutter_swiper_null_safety | Flutter Package替代它

将此包用作库

依赖它

运行此命令：

 $ flutter pub add flutter_swiper_null_safety

这将向你的包的pubspec.yaml添加一行代码（并运行一个隐式的flutter pub get）：

dependencies:
  flutter_swiper_null_safety: ^1.0.2

将其导入

在Dart代码中，您可以使用：

import 'package:flutter_swiper_null_safety/flutter_swiper_null_safety.dart';
