There are a few ways we might go about doing this: 1. Use native maps widget for each platform to render the map 2. Use maps widget for each platform to render to a texture and draw the map ourselves 3. Develop a custom maps SDK for Sky The second option would be ideal but may not be possible. We should investigate which approach is best and build a demo app. _Copied from original issue: domokit/mojo#310_

1 Fix
Implement Inline Google Maps Support in Flutter
The lack of inline support for Google Maps in Flutter is due to the absence of a dedicated widget that can render maps natively across platforms. Current options either require platform-specific implementations or custom SDK development, which complicates integration and performance.

- 1
Research Native Map Integration
Investigate existing native map widgets for both iOS and Android to determine the feasibility of using them directly within Flutter. This includes reviewing the APIs and capabilities provided by Google Maps SDK for iOS and Android.
- 2
Create a Flutter Plugin for Google Maps
Develop a Flutter plugin that wraps the native Google Maps SDK for both platforms. This plugin should expose a Dart interface that allows Flutter developers to easily integrate maps into their applications.
dartimport 'package:flutter_google_maps/flutter_google_maps.dart'; GoogleMap( initialPosition: GeoCoord(37.7749, -122.4194), mapType: MapType.roadmap, onMapCreated: (GoogleMapController controller) { // Additional setup if needed }, ); - 3
Implement Map Rendering to Texture
If direct native integration is not feasible, explore rendering the map to a texture and displaying it in Flutter. This will require creating a platform channel to communicate between Flutter and the native code, allowing for map updates and interactions.
dartMethodChannel channel = MethodChannel('com.example.maps'); channel.invokeMethod('updateMap', {'latitude': 37.7749, 'longitude': -122.4194}); - 4
Build a Demo Application
Create a simple demo application that showcases the inline Google Maps functionality. This app should allow users to interact with the map, such as zooming and panning, and should demonstrate the integration of the map within a Flutter layout.
- 5
Test Across Platforms
Thoroughly test the implementation on both iOS and Android devices to ensure that the map renders correctly and performs well. Pay attention to edge cases such as different screen sizes and orientations.
Validation
Confirm the fix by running the demo application on both iOS and Android devices, ensuring that the Google Maps widget displays correctly and is fully interactive. Check for any performance issues or crashes during usage.
