ios - 如何在 AppDelegate.swift 中使用 Firebase Remote Config？

Question

基于 advice ，我想使用 Firebase Remote Config 管理 API key 避免像 google_maps_flutter 这样的硬编码 API key 建议。它有一个像这样的 AppDelegate.swift:

import UIKit
import Flutter
import GoogleMaps

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GMSServices.provideAPIKey("YOUR KEY HERE")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

如何修改以上内容以从 Firebase Remote Config 获取 API key ，然后将其传递给 GMSServices？

基于此article ，我想到了:

import UIKit
import Firebase
import Flutter
import GoogleMaps
//import os.log

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    RemoteConfig.remoteConfig().fetchAndActivate() { status, error in
      let apiKey : String = RemoteConfig.remoteConfig()["Google_Maps_SDK_for_iOS_API_KEY"].stringValue ?? "MISSING";
      // os_log("Google_Maps_SDK_for_iOS_API_KEY = '%@'", apiKey)
      GMSServices.provideAPIKey(apiKey)
    }
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

有没有更好的办法？
