popGestureEnabled property Null safety

bool popGestureEnabled

Whether a pop gesture can be started by the user.

Returns true if the user can edge-swipe to a previous route.

Returns false once isPopGestureInProgress is true, but isPopGestureInProgress can only become true if popGestureEnabled was true first.

This should only be used between frames, not during build.


bool get popGestureEnabled => _isPopGestureEnabled(this);
