popGestureEnabled property
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.
Implementation
bool get popGestureEnabled => _isPopGestureEnabled(this);
