I am getting following error, when I am trying to display GoogleMap inside a column widget.

Column(
children: [
GoogleMap(
mapType: MapType.normal,
initialCameraPosition: CameraPosition(target: _center, zoom: 15),
),

Unable to find file while writing code following guide document.
I created a new plutter project through the Android studio, and my Runner folder looks like this.

There are no AppDelegate.m and AppDelegate.h files, but only AppDelegate.swift file exist. How do I proceed with the guide in this case?

https://codelabs.developers.google.com/codelabs/google-maps-in-flutter/#5

_markers[office.name] = marker;
// should be
setState(() {
  _markers[office.name] = marker;
});

I've followed the instructions 3-4 times, but I keep getting the same result. I even tried updating to the 0.5.31 version of the google maps plugin. I tried a different center point, but still no map.

I get the same result on Android as well. Also cloning the code here and running it produces the same issue.

The widget seems to draw (see google logo and location icon at the bottom), but no actual map shows up. I'm at a loss.

I created an API key for use on Android and added it to the manifest file. However I was seeing a message something like 'API not authorized' when I ran the app (via AndroidStudio) on my LG V30 phone. Also, the app ran but no map displayed. I eventually figured out that I needed to enable the "Maps SDK for Android" API in Google Cloud Platform. (IOS users probably need to enable the Maps SDK for iOS as well. It would be helpful to explicitly state this.

I'm using google_maps_flutter: ^0.5.11

I just wanna know that how can i fix it .. thankx

Flutter is updated with Swift, but the Codelab still consists of Objective-C
Can you add the swift code?

Target url doesn't exist: import 'package:google_maps_flutter/google_maps_flutter.dart';

please update this

The section under Adding an API key for an iOS app

You also need to add a setting to ios/Runner/Info.plist. This entry forces Flutter on iOS into a single threaded mode, which is required for the platform view embedding to work. This technical restriction is being worked on and will be lifted before Google Maps moves out of Developer Preview.

Mentions that

This technical restriction is being worked on and will be lifted before Google Maps moves out of Developer Preview.

Google Maps is out of developer preview right?

I followed as lesson shows but still, there are multiple errors:

I got this error when I was following the code lab
Generator cannot target libraries that have not been migrated to null-safety. package:nearme/src/locations.dart:10:7 ╷ 10 │ class LatLng { │ ^^^^^^ ╵ [SEVERE] Failed after 95ms pub finished with exit code 1

New version of flatter app does not generate ios/Runner/AppDelegate.m, it's creating AppDelegate.swift file & instruction to update can be taken from here

Cannot find the file – ios/Podfile, mentioned there.
I feel the tutorial seems to be outdated. I think they should update the tutorial itself.

AppDelegate.m renamed to .swift file. So is the code lines referenced doesn't match either in Step 4 for ios platform
