【问题描述】：
我正在使用 flutter 2.0.0 并将其从 flutter 2.2.3 降级，但仍然无法解决问题。
我已经关注了以下问题：
- Flutter Insecure http is not allowed by platform
- Bad state: Insecure HTTP is not allowed by platform:
- How to solve insecure http not allowed by platform flutter?
- Insecure HTTP is not allowed by platform
当然还有官方文档here。
所以，我正在尝试使用 http://my-ip:5000 之类的 URL 访问我的 Azure VM 上的本地主机。我已经完成了以下步骤，但仍然无法访问它。
注意：当我用 POSTMAN 测试它时它工作正常
