我刚按照Firebase建议的步骤将firebase导入到flutter应用程序中，同时将应用程序添加到firebase项目中。然后，我为PhoneAuth编写了代码。在运行该应用程序时，我得到的是OTP，但是当我输入OTP并单击调用“ signInwithcredential（）”方法的按钮时，该应用程序将崩溃。 这是日志-

用户正在使用该电话号码在Firebase中创建，但应用程序在通过OTP签名后立即崩溃。
答案 0 :(得分：0)
将这两行添加到android / gradle.properties文件中，为我解决了此问题：
android.useAndroidX=true
android.enableJetifier=true
答案 1 :(得分：0)
我通过将Flutter项目迁移到AndroidX解决了该问题。供参考，请遵循this guide
