What's Changed

[!NOTE] This release has breaking changes.
We apologize for the quick change in 0.24.0: this version definitively stabilizes the signatures of feature interaction callbacks.

This release restores the feature id and makes the Annotation parameter nullable for all feature interaction callbacks (tap / drag / hover).
This unblocks interaction with style-layer features not managed by annotation managers (i.e. added via addLayer* / style APIs).

[!WARNING]

Breaking Changes

• Tap: OnFeatureInteractionCallback → (Point<double> point, LatLng coordinates, String id, String layerId, Annotation? annotation).

• Drag: OnFeatureDragCallback → (Point<double> point, LatLng origin, LatLng current, LatLng delta, String id, Annotation? annotation, DragEventType eventType).

• Hover: OnFeatureHoverCallback → Point<double> point, LatLng coordinates, String id, Annotation? annotation, HoverEventType eventType).

• Update existing listeners: The short‑lived 0.23.0-only signatures (without id) are removed.

  • For unmanaged style layer features annotation is null (unmanaged means sources/layers you add via style APIs like addGeoJsonSource + addSymbolLayer).
  • For managed annotations it is the Annotation object.

Reasoning

In 0.23.0 the move to annotation objects inadvertently dropped interaction for unmanaged style features. Reintroducing id (and making annotation nullable) normalizes all three interaction paths without creating phantom annotation wrappers.

Migration Example

Before (0.23.0):

controller.onFeatureTapped.add((p, latLng, annotation, layerId) {
  print(annotation.id);
});

After (>=0.24.0):

controller.onFeatureTapped.add((p, latLng, id, layerId, annotation) {
  print('feature id=$id managed=${annotation != null}');
});

Refactor / Quality

• (web) Refactored onMapClick (degenerate bbox + interactive layer filter) to surface features inserted via style APIs (unmanaged style-layer features) in onFeatureTapped (previously skipped; returned now with id, layerId and annotation = null) (#646).
• (web) Ensure map container stretches vertically by adding style.height = '100%' to the registered div (prevents occasional zero-height layout issues in flexible parents) (#641)
