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 文件中：

在应用程序委托 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

我的颤振项目有一个 AppDelegate.swift 文件而不是一个 AppDelegate.m 文件，我不确定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)
  }
}

谁能帮帮我？

Answer 1

您可以按如下方式添加您的 API 密钥：

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 上添加以下行

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