每个Flutter iOS构建中使用不同的Google Maps API密钥

Question

据我理解从 google_maps_flutter 文档中，我们需要在 AppDelegate.swift 中声明谷歌地图 API 密钥，如下所示：

GMSServices.provideAPIKey("YOUR KEY HERE")

有没有一种方法可以在每个口味构建中使用不同的API密钥？例如开发和生产各有不同的API密钥。

我使用了主动编译条件（Active Compilation Conditions）来解决这个问题：

1. In Xcode, go to PROJECT -> Runner -> Build Settings and search for 'active compilation conditions'. Add a text value for each different flavor.

2. in AppDelegate.swift, add preprocessor conditional statements to execute different code for different flavors, in our case providing a different API key:

   import UIKit
   import Flutter
   import GoogleMaps
   
   @UIApplicationMain
   @objc class AppDelegate: FlutterAppDelegate {
     override func application(
       _ application: UIApplication,
       didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
     ) -> Bool {
   
       // Using active compilation conditions to provide the right API key for the right flavor.
       #if DEV
           GMSServices.provideAPIKey("<API key for DEV project>")
       #elseif QA
           GMSServices.provideAPIKey("<API key for QA project>")
       #elseif PROD
           GMSServices.provideAPIKey("<API key for PROD project>")
       #endif
   
       GeneratedPluginRegistrant.register(with: self)
       return super.application(application, didFinishLaunchingWithOptions: launchOptions)
     }
   }
