Question

它一直对我说 要求您的应用程序迁移到 Android 嵌入 v2。请按照以下步骤操作 https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

Answer 1

注意...与执行此步骤相同 https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects 但我让那些无法遵循这些步骤的人变得更容易......希望有所帮助。

尝试多种方法处理后，

我最终得到了一个足够好的解决方案

只需在项目中打开此文件并复制>>粘贴此代码行即可工作.......请确保删除此文件中的所有代码行并将其替换为新代码行。

     FlutterApplication and put your custom class here. -->
