当我关注https://codelabs.developers.google.com/codelabs/flutter-firebase/并且我下载了google-services.json时,我尝试在Android上运行flutter应用时遇到此错误。
checkIfNonZero():boolean{
const a=0;
const b=1;
const c=0;
const d=0;
//Regular way would be as below.
//How can this use some library instead of doing comparison for each variable
if(a>0 || b>0 || c>0 || d>0){
return true;
}
return false;
}
现在在我的google-services.json中我可以看到api_key数组是emtpy:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugGoogleServices'.
> Missing api_key/current_key object
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
* Get more help at https://help.gradle.org
BUILD FAILED in 21s
Finished with error: Gradle build failed: 1
我尝试下载新的google-services.json但结果相同。
任何人都知道如何生成api_key?
答案 0 :(得分:1)
首先,访问Firebase控制台。
选择您的项目,访问“项目设置”(可通过单击“项目概述”访问)。
现在,点击“3点”,然后点击“设置”。
在“项目设置”屏幕上,复制“Web API密钥”(例如:AIzaSyAjo3TYy8p_mjj3jMDcxTPrkwDF2dL8lwl)。
现在转到您的项目并转到“google-services.json”文件(位于“\ android \ app \ google-services.json”下)
在文件代码“google-services.json”中找到包含以下代码的行:
"api_key": [],
括号内“[]”输入以下代码:
{
"current_key": "<paste here your Web API Key>"
}
将Web API密钥粘贴在双引号之间(请参阅下面的示例):
"api_key": [
{
"current_key": "AIzaSyAjo3TYy8p_mjj3jMDcxTsdFkwDF2dL8NWs"
}
],
