Duplicate plugin key: FLTGoogleMapsPlugin

Question

I am trying to prepare a demo project using Google maps with flutter but don't know why getting crash with this error in console

Runner[39966:208120] *** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Duplicate plugin key:
FLTGoogleMapsPlugin'

I have followed this link flutter-io

Any help is appreciated thanks in advance.

Just to clarify the comments and provide a final answer - you should be careful that [GeneratedPluginRegistrant registerWithRegistry:self] is not called twice in your AppDelegate.m file.

As per the Google Maps Flutter plugin readme, your AppDelegate.m should look like this:

#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
