在Flutter应用中从源代码管理中隐藏Google Maps API密钥 [英] Hide Google Maps API key from source control in a Flutter app

问题描述

要启用Google Maps SDK，您必须更新: 适用于Android的 android/app/src/main/AndroidManifest.xml ， 和 ios/Runner/AppDelegate.m for iOS with your API key

To enable the Google Maps SDK you must update: android/app/src/main/AndroidManifest.xml for android, and ios/Runner/AppDelegate.m for ios with your API key.

我不想将我的API密钥签入源代码管理中.

I don't want to check in my API key into source control.

是否可以用.env文件和.gitignore隐藏该键?

Is there a way to hide this key with a .env file and .gitignore?

这里的最佳做法是什么?

What is best practice here?

推荐答案

您可以将api密钥设置为环境变量，这些变量只能在本地计算机上的构建过程中读取.创建一个环境变量MAPS_API_KEY ="your-key-here"，然后将这些行添加到 [您的项目]/android/app/build.gradle

You can set your api keys as environment variables which can be read during build on your local machine only. Create an env variable MAPS_API_KEY="your-key-here", then add these lines to [your-project]/android/app/build.gradle

 defaultConfig {
        manifestPlaceholders = [mapsApiKey: "$System.env.MAPS_API_KEY"]
    }

然后您可以使用mapsApiKeys在AndroidManifest.xml中传递您的api密钥

and then you can use the mapsApiKeys to pass your api keys in AndroidManifest.xml

 <meta-data android:name="com.google.android.geo.API_KEY"
                android:value="${mapsApiKey}"/>

对于ios，将它们添加到AppDelegate.m

For ios, add these to AppDelegate.m

NSString* mapsApiKey = [[NSProcessInfo processInfo] environment[@"MAPS_API_KEY"];

[GMSServices provideAPIKey:mapsApiKey];
