java - 在 flutter 中添加Firebase包时出错

Question

我正在尝试在Flutter应用中设置Firebase。我遵循了Firebase网站以及flutter网站上的所有指示来设置Firebase，包括编辑pubspec.yaml文件，编辑应用程序级别的build.gradle文件和项目级别的build.gradle文件。当我运行应用程序时，出现此错误

我的Java版本是openjdk版本“1.8.0_252”
我如何摆脱这个错误？

Answer 1

确保将它们添加到gradle.properties文件中

android.useAndroidX=true
android.enableJetifier=true

另外，您似乎正在使用旧版本的 firebase_core_web。尝试更新它。
