适用于Flutter iOS Swift设置的谷歌地图

Question

设置官方Google Maps for Flutter插件的说明包括将Google API密钥添加到AppDelegate.m文件：

在应用程序代理ios/Runner/AppDelegate.m:中指定您的API密钥

#include "AppDelegate.h" 
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[GMSServices provideAPIKey:@"YOUR KEY HERE"];
[GeneratedPluginRegistrant registerWithRegistry:self];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

我的flutter项目有一个AppDelegate.swift文件，而不是AppDelegate.m文件，我不知道如何添加所需的密钥，因为语法不同：

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

有人能帮我吗？

Answer 1

您可以添加您的API密钥如下：

AppDelegate.swift：

import UIKit
import Flutter
import GoogleMaps // Add this line!
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
GMSServices.provideAPIKey("YOUR_API_KEY")  // Add this line!
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}

还有一件事，别忘了在ios/Runner/Info.plist上添加下一行

<key>io.flutter.embedded_views_preview</key>
<true/>
