- Around line 94-106: Update the color resolution logic around readProperty and
applyHexOpacity so the base color uses the feature color when present, otherwise
fallback, while still returning the fallback when no usable color or opacity is
defined. Apply fill-opacity or stroke-opacity to that resolved base color,
including when only the opacity property is provided, and preserve existing

around ringToCoordinates and the Polygon/MultiPolygon conversion paths to retain
interior rings instead of warning and discarding them. Carry each polygon’s
holes through to native rendering for both geometry types, preserving the

Clamp descriptor.zIndex before assigning marker.zIndex.
Double.toFloat() converts 1e308 to Infinity, while iOS maps the value to Int32.max. Match iOS by mapping non-finite values to 0 and clamping finite values to the supported range. Add a test for a large finite value.

Google Maps Android SDK BitmapDescriptorFactory defaultMarker(float) hue saturation brightness alpha documentation
💡 Result:
In the Google Maps Android SDK, the BitmapDescriptorFactory.defaultMarker(float hue) method allows you to customize the color of the default marker icon by specifying a hue value [1][2][3]. The hue parameter is a float representing a position on a color wheel, with a range of 0 to 360 [1][4][5]. The SDK provides several predefined constant values for common colors, such as BitmapDescriptorFactory.HUE_RED, HUE_YELLOW, and HUE_AZURE [1][3][5]. Regarding saturation, brightness (or value), and alpha: The Google Maps Android SDK does not provide a programmatic way to adjust the saturation, brightness, or alpha of the default marker through the BitmapDescriptorFactory.defaultMarker method [5][6][7]. These properties are effectively hardcoded into the internal implementation of the default marker [5][8]. If you require precise control over these color properties, the recommended approach is to use a custom marker image (icon) instead [3][6]. You can load your own Bitmap asset using other methods in the BitmapDescriptorFactory class, such as: - fromAsset(String assetName) [3] - fromBitmap(Bitmap image) [3] - fromFile(String fileName) [3] - fromPath(String absolutePath) [3] - fromResource(int resourceId) [3] This allows you to define the exact appearance of your marker, including saturation, brightness, and transparency (alpha) [3].

Preserve the full marker color on Android.
String.toColorInt accepts ARGB values, and GeoJSON marker-opacity can encode alpha in that value. BitmapDescriptorFactory.defaultMarker(float) uses only hue, so #FFFFFF and #000000 both render as the red marker. This also differs from iOS, which passes the full UIColor. Use a full-color tint path or restrict markerColor to hue-only values.

Apple MapKit MKAnnotationViewZPriority zPriority selectedZPriority documentation
💡 Result:
In MapKit, zPriority and selectedZPriority are properties of MKAnnotationView introduced in iOS 14 that allow developers to control the visual stacking order (z-index) of overlapping annotation views [1][2]. zPriority defines the relative importance of an annotation view when it is in an unselected state, while selectedZPriority defines the priority when the view is selected [3][4]. These properties use the MKAnnotationViewZPriority type, which provides constants to manage ordering [5][4]. Key components include: MKAnnotationViewZPriority Constants: - defaultUnselected: The default priority for an unselected view [5]. - defaultSelected: The default priority for a selected view [5]. - min: The minimum allowed priority [5]. - max: The maximum allowed priority [5]. By assigning these values, you can ensure that important annotations, such as the user location, appear above other markers on the map [2]. For example, setting zPriority to.max helps ensure a specific annotation remains visually prominent [2]. For further implementation details, you can refer to the official Apple Developer documentation for MKAnnotationView [4] and MKAnnotationViewZPriority [5].

Apply marker.zIndex to both MapKit priority properties.
When marker.zIndex is present, assign the mapped value to both zPriority and selectedZPriority. When it is absent, use .defaultUnselected and .defaultSelected, respectively. Apply this in NitroImageAnnotationView.swift and NitroPinAnnotationView.swift; otherwise, selecting a marker can use MapKit’s default selected priority.

Qualify the zIndex documentation by platform.
properties.zIndex does not always override drawing order. docs/geojson.md Line 38 states that MapKit does not expose shape overlay z-ordering. Update this sentence to qualify Apple polygon and polyline behavior. The current wording overpromises the result for those overlays.
