cupertino_will_pop_scope 1.0.1

This package extends the default iOS page transition to support the invocation of `onWillPop` in a [WillPopScope] widget.

[1.0.1]

• Introduced a new ConditionalWillPopScope widget which makes it possible to add willPop callbacks conditionally.
• Added a small time delay before calling the route's willPop callbacks, to accomodate for the screen's "rewind" animation.
• Increased the distance a screen is allowed to be dragged before the gesture is terminated. (From 33% to 42%.)
• Updated the example app and docs.

[1.0.0]

• Initial release.
