firebase - firebase_messaging 插件出错

问题描述

我正在向firebase_messaging我的项目添加插件，以前的版本已经firebase_messaging并且工作正常。我正在将我的项目从 using 转移flutter_webview_plugin到 using webview_flutter，因此我相应地更改了我的代码，但我开始遇到错误。我创建了新项目并引发了相同的错误，但是当我删除它时firebase_messaging它开始工作。

这是错误：-

解决方案

在 github 上查看这个问题。此外，如果您使用的是最新的插件，您应该迁移您的项目以与AndroidX兼容。并确保您compileSdkVersion与这些插件兼容。ps：flutter clean在你尝试那些东西之后。
