Jan 1, 2026January 2026 monthly summary for Esri/arcgis-maps-sdk-flutter-samples. Focused on dependency hygiene and stability by upgrading the file_picker library to the latest compatible releases. Delivered a two-step upgrade from 10.2.0 to 10.3.10 (via 10.3.8 intermediate) across two commits, with these changes: update file_picker (#427) and Update the File_Picker 10.3.10 (#431). This work reduced build and runtime risks, improved file handling capabilities in the samples, and aligned the repository with current Flutter ecosystem standards. No customer-reported defects were addressed this month; the primary value was maintainability and forward compatibility.

Jul 1, 2025July 2025 monthly summary for Esri/arcgis-maps-sdk-flutter-samples focused on delivering robust, developer-friendly Flutter samples and improving animation reliability across GeoViews. Key features delivered include a ticker-based ImageOverlay animation sample with improved frame control, caching improvements, and UI simplification; plus a new Viewpoint synchronization sample for MapView and SceneView with gesture-based enhancements. A targeted bug fix addressed a crash in the image animation feature by using file URIs and normalizing animation frame rates. These efforts reduce runtime crashes, enhance animation smoothness, and enable easier cross-view coordination for developers, driving faster prototyping and higher-quality demos.

Feb 1, 2025February 2025: Delivered two key features in Esri/arcgis-maps-sdk-flutter-samples that enhance routing reliability and cross-platform consistency. The Dynamic Route Recalculation Sample App introduces a rerouting workflow with a README and core Dart navigation code, plus theme updates to support the new sample. The Cross-Platform Navigation Timing and Voice Guidance Stability work aligns location update intervals with iOS, stabilizes voice guidance by refining the speech engine readiness, ensures TTS stops when navigation ends, and removes the simulation speed parameter.
