install method

  1. @override
void install (
  1. OverlayEntry insertionPoint
)
inherited

Called when the route is inserted into the navigator.

Use this to populate overlayEntries and add them to the overlay (accessible as Navigator.overlay). (The reason the Route is responsible for doing this, rather than the Navigator, is that the Route will be responsible for removing the entries and this way it's symmetric.)

The insertionPoint argument will be null if this is the first route inserted. Otherwise, it indicates the overlay entry to place immediately below the first overlay for this route.

Implementation

@override
void install(OverlayEntry insertionPoint) {
  super.install(insertionPoint);
  _animationProxy = ProxyAnimation(super.animation);
  _secondaryAnimationProxy = ProxyAnimation(super.secondaryAnimation);
}
