Firebase尚未正确初始化.您是否添加了"google-services.json"归档到项目 [英] Firebase has not been correctly initialized. Have you added the "google-services.json" file to the project

问题描述

运行我的应用程序时出现此错误.我将google-services.json下载到了我的android/app文件夹中.我已经输入了

I'm getting this error when i run my app. I downloaded the google-services.json into my android/app folder. I have put in the

应用插件:"com.google.gms.google-services"

apply plugin: 'com.google.gms.google-services'

进入我的app/build.gradle文件.最初，我没有将应用插件"所以我把它放在后面，似乎没有什么不同.我也把我的

into my app/build.gradle file. Originally i had not put in the "apply plugin" so i put it in later and it doesn't seem to have made a difference. I also put my

classpath'com.google.gms:google-services:4.3.5'

classpath 'com.google.gms:google-services:4.3.5'

into my android/build.gradle. The entire error when i run the app is

推荐答案

感谢@Nishuthan S为我发布解决方案.您可以在评论中看到他的建议.

Thank you to @Nishuthan S for posting the solution for me. As you can see in the comments what he suggested.

尝试 Flutter创建.然后 flutter clean ，然后 flutter run ，如果这样不起作用，则可以尝试备份lib文件夹并 pubspec 删除项目，创建一个新项目以相同的程序包名称替换lib和 pubspec –

try flutter create . then flutter clean then flutter run if that doesn't work you can try back up your lib folder and pubspec delete the project create a new project in the same package name and replace lib and pubspec –

按照他的建议去做后，我去阅读了图像，字体和声音，并将其返回给新项目.我输入了 flutter pub get 来检查pubspec.yaml是否工作正常.我将依赖关系从firebase读入正确的文件中，这取决于您自己的项目，可在其网站上找到.现在该项目正在运行.谢谢大家的帮助

After i did what he suggested, i went and readded the images, fonts and sounds back to the new project. I typed flutter pub get to check pubspec.yaml was working fine. I readded the dependencies from firebase into the correct files, this is found on their website depending on your own project. Now the project is working. Thanks to all for your help
