zoomToggleOnDoubleTap constant

OnStageTap const zoomToggleOnDoubleTap

Sentinel handler — pass to onDoubleTap (here or on a DisplayConfig) to opt in to the package's default zoom toggle (baseRect ↔ fit-cover-at-focal at the tap position). Detected by identity inside Stage so the implementation can use the live Stage instance to animate the rect; invoking this function directly is a no-op.

Implementation

static const OnStageTap zoomToggleOnDoubleTap = _zoomToggleSentinel;
