How to Effectively Add Google Maps to a Flutter Module in a Native iOS App

Integrating Google Maps within a Flutter module for a native iOS app can be a complex task. Developers often face issues, particularly when trying to ensure the Google Maps SDK is properly initialized across both the Flutter module and the main iOS application. In this guide, we'll guide you through the steps needed to resolve the common crash issue related to Google Maps integration within a Flutter module.

Understanding the Problem

When you try to add Google Maps to a Flutter module that is integrated into a native iOS app, you may encounter the following error:

This error often arises because the Google Maps SDK is not initialized correctly in both the native app and the Flutter module. Doing it only in the AppDelegate.m of the main app may not suffice, especially since the .iOS folder of the Flutter module is regenerated with every build, which can overwrite your initializations.

The Solution

To successfully integrate Google Maps into your Flutter module, you need to take additional steps to ensure proper initialization. Here's how to tackle this issue effectively:

Step 1: Adding Google Maps Initializer in Your Flutter Module

Create Initialization Method: In your Flutter module, you will need to create an initializer method for Google Maps. This method will set the API key for the Google Maps SDK that Flutter will use.

Step 2: Call From AppDelegate of Your Native iOS App

Modify the AppDelegate: Next, you will need to ensure that this initializer is called from the AppDelegate.m of your main native iOS application.

Step 3: Testing the Integration

Run Your Application: After adding the above initializations, you should run your native iOS application with the Flutter module integrated. Ideally, the initialization should now occur smoothly across both environments, preventing any crashes related to Google Maps.

Final Thoughts

By following these steps, you will have effectively set up Google Maps in your Flutter module that is embedded within a native iOS app. This dual initialization method ensures that both the Flutter component and the native application are aware of the Google Maps SDK, allowing you to harness the functionality without encountering crashes. If you encounter any issues, make sure to double-check your API keys and the paths to your Flutter module in the AppDelegate.
