+ * A declarative Compose wrapper for the Google Maps 3D SDK [Map3DView].
+ *
+ * This composable allows you to display a 3D map and control it using standard Compose state.
+ * It handles the underlying view lifecycle and synchronizes state objects (markers, polylines,
+ * polygons, and models) with the imperative SDK instance.
+ *
+ * Literate Programming Note: Initialization in the Maps 3D SDK is tricky. We cannot rely solely
+ * on `getMap3DViewAsync`. We must wait for `setOnMapReadyListener` to fire before adding any
+ * content, otherwise additions might be ignored. Furthermore, this listener only fires ONCE
+ * in the lifetime of the application. To handle this, we track readiness globally in
+ * [Map3DRegistry] and defer all state updates until we are certain the map is ready.
+ *
+ * @param camera The hoisted camera state to apply to the map.
+ * @param markers The list of markers to display on the map.
+ * @param polylines The list of polylines to display on the map.
+ * @param polygons The list of polygons to display on the map.
+ * @param models The list of 3D models to display on the map.
+ * @param cameraRestriction The camera restriction to apply to the map.
+ * @param mapMode The map mode (e.g., SATELLITE, HYBRID).
+ * @param modifier The modifier to apply to the layout.
+ * @param options The options to initialize the [Map3DView] with.
+ * @param onMapReady Optional callback invoked when the [GoogleMap3D] instance is ready.

+ Task: Act as a Visual QA system to verify an Android application screenshot. Compare the

+
+ 1. Map Verification
+ Confirm that a map is visible in the background. The map should be centered on the Sydney,
+ Australia area. Major landmarks or labels like Sydney, Hornsby, and Cronulla should be visible.
+ Be flexible with minor labels as they may change, but the general geographic layout must match the reference.
+ 2. Marker Content and Styling
+ There must be exactly six markers on the screen. Verify each of the following:
+
+ * Marker A: Text is "Default". Background is white. Orientation is standard horizontal.
+ * Marker B: Text is "Custom color". Background is cyan/light blue. Orientation is standard horizontal.
+ * Marker C: Text is "Rotated 90 degrees". Background is red. Both the bubble and the text are rotated 90 degrees clockwise.
+ * Marker D: Text is "Rotate=90, ContentRotate=-90". Background is purple. The bubble is rotated 90 degrees clockwise, but the text inside remains horizontal.
+ * Marker E: Text is "ContentRotate=90". Background is green. The bubble is horizontal, but the text inside is rotated 90 degrees clockwise.
+ * Marker F: Text is "Mixing different fonts". Background is orange. The word "Mixing" must be in italics. The words "different fonts" must be in bold.
+
+ 3. Spatial Grid Verification
+ Verify that the markers are positioned correctly relative to one another in a rough grid layout:
+
+ * Top-Left: The Orange marker ("Mixing different fonts").
+ * Top-Right: The Green marker ("ContentRotate=90").
+ * Middle-Left: The Red marker ("Rotated 90 degrees").
+ * Middle-Center: The White marker ("Default").
+ * Bottom-Left: The Purple marker ("Rotate=90, ContentRotate=-90").
+ * Bottom-Right: The Cyan marker ("Custom color").
+
+ 4. Output Requirements
+ Provide your response in the following format:
+
+ * Status: [PASSED or FAILED]
+ * Justification: Provide a concise explanation for the classification. If FAILED, list the
+ specific markers or map elements that do not meet the criteria.

Subject: [PATCH 16/29] feat: Migrate Sanitas Loop polyline to maps3d-compose
- Added PolylineConfig enhancements (drawsOccludedSegments, onClick).
- Created PolylinesActivity with Sanitas Loop demo (double polyline, hovering).
- Wired click listener to show Toast via rememberCoroutineScope.
- Removed useless MAPS_API_KEY warning from build files.

Subject: [PATCH 19/29] feat: Add extruded museum and click support to Polygons
example
- Added extruded museum building to PolygonsActivity.kt using a custom extrusion helper.
- Added onClick callback to PolygonConfig in DataModels.kt and handled it in Map3DState.kt.
- Updated PolygonsActivity.kt to use click listeners on the zoo and museum polygons.
- Expanded unit tests in MappersTest.kt to cover default values.
- Cleaned up fully qualified names in DataModels.kt.
- Added missing imports in PolygonsActivity.kt to resolve compilation errors.

Subject: [PATCH 20/29] feat(compose): Add Map Options and Popovers samples,
and fix CameraRestriction crash
- Add MapOptionsActivity to demonstrate map options and camera restrictions.
- Add PopoversActivity to demonstrate popovers.
- Implement toValidCameraRestriction() extension function to sanitize CameraRestriction parameters.
- Provide safe defaults from defined ranges when parameters are null to prevent crashes in the native SDK.
- Ensure min <= max for altitude, heading, and tilt by swapping values if necessary.
- Refactor GoogleMap3D.kt to use the new extension function.
- Update MainActivity and AndroidManifest to include new samples.
- Clean up SampleScreens.kt.

Subject: [PATCH 21/29] feat(maps3d-compose): Implement Models sample and
refactor demo architecture
- Moved BasicMapSample to its own file for better modularity.
- Implemented ModelsActivity to demonstrate loading 3D models and orchestrating cinematic camera animations.
- Registered ModelsActivity in the manifest and updated MainActivity to launch it.
- Added unit tests in UtilitiesTest.kt for CameraRestriction validation.
- Removed old placeholders from SampleScreens.kt.
- Included pre-existing changes in PolylinesActivity and deletion of properties file.

Subject: [PATCH 22/29] Refactor Basic Map sample to launch as a separate
activity
- Refactor "Basic Map with Marker & Polyline" sample to launch BasicMapActivity instead of using inline state.
- Create BasicMapActivity and register it in the manifest.
- Delete empty SampleScreens.kt file.
- Simplify polyline in PolylinesActivity to fix visual test failure.
- Increase timeout and add delay in Maps3DVisualTest for map interactions.
- Add log in MapInteractionsActivity for debugging clicks.
- Fix ktlint violations and clean up unused imports across the project.

Subject: [PATCH 23/29] feat(maps3d-compose): Add declarative Popover support
and update documentation
- Implement `PopoverConfig` in `DataModels.kt` to support declarative popovers in Compose.
- Add `popovers` parameter and `onMapClick` callback to `GoogleMap3D` composable to enable state-driven popover management and map interaction.
- Implement `syncPopovers` in `Map3DState.kt` to handle the mapping between Compose configurations and native SDK Popover instances.
- Refactor `PopoversActivity` in `maps3d-compose-demo` to demonstrate the declarative API, setting `autoPanEnabled` and `autoCloseEnabled` to false for predictable, state-driven UI behavior.
- Add `README.md` files to both `maps3d-compose` and `maps3d-compose-demo` modules to clarify their purpose as reference implementations.
- Relocate and expand `compose_api_coverage.md` into a comprehensive checklist tracking specific SDK classes and listeners, highlighting unsupported features like `Map3DViewUiController`.
- Update root `README.md` to document the new modules with explicit warnings about their experimental nature.

+- **Basic Map**: A simple map with camera controls.
+- **Map Options**: Demonstrates changing map modes (Satellite/Hybrid) and applying camera restrictions.
+- **Models**: Shows how to add and interact with 3D models (glTF) on the map, including click listeners.
+- **Popovers**: Demonstrates the declarative Popover API, rendering Compose content inside native map popovers.
+
+## How to Run
+
+You can install and run this demo on a connected device or emulator using:
+```bash
+./gradlew :maps3d-compose-demo:installDebug
+```
+Then launch any of the activities via the launcher or ADB.

+# Maps 3D Compose Wrapper (Experimental)
+
+This library provides a Jetpack Compose wrapper for the Google Maps 3D SDK for Android.
+
+> [!WARNING]
+> **Status**: This implementation is a **Work In Progress (WIP) experiment** and serves as a **reference implementation**. It is not intended for production use. APIs may change significantly in the future.
+
+## What's Inside
+
+This module contains the source code for the Compose wrapper:
+- **`GoogleMap3D`**: The main Composable function to display a 3D map.
+- **Declarative State**: Support for adding Markers, Polylines, Polygons, 3D Models, and Popovers via standard Compose state lists.
+- **Camera Hoisting**: Ability to hoist the camera state for animations and position tracking.
+
+## Current Coverage
+
+For a detailed list of supported features and missing APIs, see [compose_api_coverage.md](./compose_api_coverage.md).

Subject: [PATCH 24/29] feat: Implement OnCameraChangedListener and add Whiskey
Compass demo (#40)
* feat: Implement OnCameraChangedListener and add Whiskey Compass demo
- Exposed onCameraChanged callback in GoogleMap3D composable.
- Added WhiskeyCompass composable in demo app.
- Added CameraChangedActivity to demonstrate camera changes with compass, tilt scale, and range scale.
- Updated compose_api_coverage.md.
* docs: Add code reference link for OnCameraChangedListener in coverage doc
* refactor: Move camera changed demo widgets to widgets package
- Moved WhiskeyCompass.kt to widgets package.
- Extracted TiltScale and RangeScale to separate files in widgets package.
- Updated CameraChangedActivity to use widgets from the new package.

Subject: [PATCH 27/29] feat: address review comments, refactor
getMap3DViewAsync, and add rotation test
- Refactor `GoogleMap3D` and `ThreeDMap` to avoid calling `getMap3DViewAsync` on every recomposition by moving it to the `factory` block of `AndroidView`.
- Use `rememberUpdatedState` in `GoogleMap3D` for callbacks to prevent stale captures.
- Add `verifyRotationMaintainsMap` visual test to verify map rendering after device rotation.
- Remove reference files in `visual-test-examples` directory as requested.
- Move Spotless plugin to versions catalog and upgrade several dependencies (Places to 5.2.0, Spotless to 8.4.0, Ktor to 3.4.2, etc.).
- Clean up `truth` library usage across modules, favoring `google-truth`.
- Fix Spotless formatting warnings in `CameraChangedActivity.kt` and `WhiskeyCompass.kt`.

- Task: Act as a Visual QA system to verify an Android application screenshot. Compare the

- rendering is correct.
-
- 1. Map Verification
- Confirm that a map is visible in the background. The map should be centered on the Sydney,
- Australia area. Major landmarks or labels like Sydney, Hornsby, and Cronulla should be visible.
- Be flexible with minor labels as they may change, but the general geographic layout must match the reference.
- 2. Marker Content and Styling
- There must be exactly six markers on the screen. Verify each of the following:
-
- * Marker A: Text is "Default". Background is white. Orientation is standard horizontal.
- * Marker B: Text is "Custom color". Background is cyan/light blue. Orientation is standard horizontal.
- * Marker C: Text is "Rotated 90 degrees". Background is red. Both the bubble and the text are rotated 90 degrees clockwise.
- * Marker D: Text is "Rotate=90, ContentRotate=-90". Background is purple. The bubble is rotated 90 degrees clockwise, but the text inside remains horizontal.
- * Marker E: Text is "ContentRotate=90". Background is green. The bubble is horizontal, but the text inside is rotated 90 degrees clockwise.
- * Marker F: Text is "Mixing different fonts". Background is orange. The word "Mixing" must be in italics. The words "different fonts" must be in bold.
-
- 3. Spatial Grid Verification
- Verify that the markers are positioned correctly relative to one another in a rough grid layout:
-
- * Top-Left: The Orange marker ("Mixing different fonts").
- * Top-Right: The Green marker ("ContentRotate=90").
- * Middle-Left: The Red marker ("Rotated 90 degrees").
- * Middle-Center: The White marker ("Default").
- * Bottom-Left: The Purple marker ("Rotate=90, ContentRotate=-90").
- * Bottom-Right: The Cyan marker ("Custom color").
-
- 4. Output Requirements

- * Justification: Provide a concise explanation for the classification. If FAILED, list the
- specific markers or map elements that do not meet the criteria.

Subject: [PATCH 28/29] refactor: Apply Spotless and reformat WhiskeyCompass
- Improve formatting of the `WhiskeyCompass` composable.
- Migrated Spotless plugin to use version catalog alias in build files.
- Increased the rendering margin in `WhiskeyCompass` to prevent visual pop-in.
