flutter - Flutter Html View 导入时返回错误

问题描述

我已经成功在pubspec.yaml中安装了依赖，退出代码为0。当我import 'package:flutter_html_view/flutter_html_view.dart';显示它已通过vs代码导入（它强调它是导入但未使用）**

但是当我保存或重新启动我的模拟器时，它会拒绝构建。返回以下错误：

解决方案

您的 SDK 限制是什么？您使用的是 2018 年的一个非常旧的版本 ( 0.2.0) package:flutter_markdown，早在 Flutter 甚至还稳定之前。使用最新的兼容版本（^0.6.2理想情况下）应该可以解决您的问题。
