Flutter google Maps ios build fail

Question

I'm trying to implement google maps in my flutter app. I'm using this version:

  google_maps_flutter: ^0.5.21+15

It works on android, but on ios there's a build fail when trying.

I discovered this:

normally my AppDelegate.swift looks like this:

import UIKit
import Flutter

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

But when I use this, as the google maps plugin says, the build fails:

import UIKit
import Flutter
import GoogleMaps

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

What Am I doing wrong?

Thanks for helping!

Solution

You've replaced UIApplication.LaunchOptionsKey with UIApplicationLaunchOptionsKey in the function signature. Replace it back to fix the error

FYI you can use some diff tool to find all places which are different in two code snippets

Thanks! very strange, cuz I got the snippet from the official google maps package on flutter. But it works! Thanks!
