maplibre_flutter_gpu 0.2.0

MapLibre maps for Flutter, rendered with Flutter GPU.

0.2.0

• Reduce default symbol rendering work during camera movement with cached text shaping and shared glyph atlases. Reference M1 Pro benchmarks with semantics disabled measured up to 95% lower UI-thread frame time (p95).
• Fix memory growth that could cause crashes during prolonged scrolling by reclaiming retired native tile resources and adapting native and Flutter cache budgets to device memory and memory pressure.
• Add MapLibreMap.fillExtrusionRendererBuilder to hide individual building parts, apply custom fragment materials, and access extruded tile geometry.
• Add SymbolSemanticsMode to control whether default labels appear in the accessibility tree.
• Fix premature clipping of map and custom GPU geometry close to the camera. MapLibreGpuMapTransform.viewProjectionMatrix now uses Flutter GPU's normalized depth range from 0 to 1.
• Keep visible maps rendering when desktop windows lose focus.
• Adjust mouse drag inertia.

0.1.1

• Keep the user location marker above custom overlayBuilder content.

0.1.0

• Add application-supplied user location with heading, horizontal accuracy, frame-aligned projection, and customizable Flutter marker builders.
• Render heatmap and hillshade layers with Flutter GPU, with new layer property types and controller methods.
• Add externally controlled cameras through MapLibreMap.cameraPosition and configurable viewport correction through CameraConstrainMode.
• Expose adopted camera and viewport metadata through MapFrameState, onFrame, MapLibreMapController.frameState, and overlayBuilder.
• Add heatmap and hillshade controls, foreground location and follow controls, and an Android TV map explorer to the examples.
• Reduce default symbol update work, native draw command memory, and offscreen planning overhead.
• Keep consecutive partial camera updates in call order without restoring stale camera values.
• Complete scroll-wheel gestures and reject cancelled two-finger taps and unintended pan flings.
• Preserve Android HTTP cancellation and allow long style paint transitions to complete.
• Raise the minimum iOS version to 15.0.

0.0.7

• Fix Vulkan rendering crashes on certain Android devices and preserve previously drawn layers.
• Fix line label scaling and spacing on tilted maps.
• Keep custom overlays aligned with the map when it resizes, including during initialization.
• Fix bounds spanning all longitudes being treated as a single meridian, which could make the camera zoom in too far.
• Make circle edge rendering consistent across blur widths and GPU drivers.

0.0.6

• Reduce symbol overlay rendering time by reusing unchanged widgets, avoiding layout work during camera movement, and batching symbol widget rendering.

0.0.5

• Improve rendering performance by reusing GPU resources across frames.
• Add Shift-drag camera tilt and Ctrl-drag rotation on Windows and Linux, plus three-finger trackpad tilt on macOS.
• Show Flutter-rendered symbol and text widgets wherever the same location appears more than once in a wide viewport at low zoom, and add MapLibreMapController.toScreenOffsets for custom overlays.
• Fix Linux startup failures caused by libpng 1.6 patch-version differences.

0.0.4

• Render symbol icons and text with closer MapLibre parity, including data-driven styling, halos, formatted text, inline images, multiple sprite sources, and style layer ordering.
• Make symbol text and icons follow roads and other lines, with support for bidirectional and vertical text.
• Add opt-in SymbolCompositingMode.fastOverlay for maps where speed is preferred over exact style layer ordering.

0.0.3

• Add Linux and Windows support for x64 and ARM64 in debug and profile modes.
• Upgrade to Flutter 3.47.0 and Dart 3.13.0.

0.0.2

• Improve Flutter GPU setup instructions and API documentation in the README.
• Fix published shader bundle packaging and runtime lookup.
• Restrict IgnorePointer to the default symbol builders instead of wrapping every widget returned by custom symbol icon and text builders.
• Stop the shared native runtime before macOS process teardown to prevent shutdown crashes.

0.0.1

• Initial development release for iOS, Android, and macOS.
• Render MapLibre fill, line, circle, raster, symbol, and fill-extrusion layers with Flutter GPU.
• Provide map camera, gesture, style, source, layer, filter, sprite, and attribution APIs.
• Support custom Flutter GPU map rendering with geographic transforms and optional shared depth for 3D content.
• Render idle maps on demand and suspend frame scheduling with the application lifecycle.
• Include examples for landmark markers, style controls, and custom GPU rendering.
