firebase - Google Services.json不存在

Question

我正在学习 flutter ，并尝试安装Firebase，它一直说找不到“google-services.json”，即使我在正确的位置，也尝试了许多其他地方，实际上说的是“退出代码1 :C:\ Users \ Samwise \ Desktop \ chatapp3 \ android \ gradlew.bat app:属性:
在[src / nullnull / debug，src / debug / nullnull，src / nullnull，src / debug，src / nullnullDebug]中查找时找不到google-services.json
registerResGeneratingTask已弃用，请使用registerGeneratedFolders(FileCollection)“

非常感谢。

def localProperties = new Properties()

if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

根据repo issue中的注释，可能尚不支持使用Google Service 3.2.0的Firebase版本:

Firebase has moved on to version 12+ and uses version 3.2.0 of the google-services Gradle plugin. The flutter/plugins repo should follow suit.

我有3.1.2可以很开心地工作，所以您可以尝试一下。

classpath 'com.google.gms:google-services:3.1.2'
