android - 注意 : Recompile with -Xlint:deprecation. 注意:一些输入文件使用或覆盖已弃用的 API

Question

当我在 flutter clean 之后运行 flutter run 或 debug my code 时显示此错误

但它只显示一次，之后它不会显示任何错误，直到我删除构建 flutter clean。有什么办法可以消除这个错误吗？或者它是否会导致任何问题，因为我在我的应用程序中还没有看到任何问题。谢谢

不用太担心。该错误与 Firebase 库有关，它在 native 实现中有一些引用已标记为已弃用的 API 的代码。

这不会在您的代码中产生任何问题，他们肯定会在下一版本的库中修复此问题。

这只会在 flutter clean 之后发生，因为那是编译它并检测到此警告的时刻。之后，编译被缓存，不再编译。
