holdMeasurement static method

Suspends frame measurement for every GlassAdaptiveScope until the returned hold is released.

Wrap heavy work of your own that competes with the glass for the GPU/CPU, so the slowdown is not mistaken for a device that cannot render the glass:

final hold = GlassAdaptiveScope.holdMeasurement();
try {
  await heavyWork();
} finally {
  hold.release();
}
