GlassPerformanceMonitor class
Monitors raster frame durations and emits a developer warning when GlassQuality.premium surfaces are active and GPU budget is exceeded.
This class is entirely static — it acts as a process-wide singleton so that multiple glass widgets share one callback and one ring buffer.
Properties
- hashCode → int

Static Properties
- activePremiumCount → int
-
Number of premium glass surfaces currently mounted.
no setter
- isRunning → bool
-
Whether the monitor is currently active.
no setter
- rasterBudget ↔ Duration
-
Raster duration budget per frame. Frames that exceed this value count
toward sustainedFrameThreshold.
getter/setter pair
- sustainedFrameThreshold ↔ int
-
Number of consecutive frames that must exceed rasterBudget before the
warning fires. Reduces false positives caused by animation spikes.
getter/setter pair
- warningEmitted → bool
-
Whether the performance warning has already been emitted this session.
no setter
Static Methods
-
reset(
) → void - Resets the consecutive-frame counter and the warning latch.
-
simulateFrameTimings(
List< FrameTiming> timings) → void -
Injects synthetic FrameTiming data directly into
_onFrameTimings. -
start(
) → void - Starts the monitor.
-
stop(
) → void - Stops the monitor and detaches the frame callback.
-
trackPremiumMount(
) → void - Called by the internal premium glass tracker when a premium glass surface mounts.
-
trackPremiumUnmount(
) → void - Called by the internal premium glass tracker when a premium glass surface unmounts.
