Google Map Setup

• To use Google Maps in your Flutter app, you need to configure an API project with the Google Maps Platform, following both the Maps SDK for Android Get API key, and Maps SDK for iOS Get API key processes. With API keys in hand, carry out the following steps to configure both Android and iOS applications.
• To add an API key to the Android app, edit the AndroidManifest.xml file in android/app/src/main . Add a single meta-data entry containing the API key created in the previous step.
• To add an API key to the iOS app, edit the AppDelegate.swift file in ios/Runner . Unlike Android, adding an API key on iOS requires changes to the source code of the Runner app. The AppDelegate is the core singleton that is part of the app initialization process
