Flutter navigator 2.0 force new state to be created - flutter

Question

I'm using the new Pages and Router APIs from Flutter's Navigator 2.0
My issue is that I have pages A and B opened and then a deepLink is called to page A. So what I do is clear the list of pages used in the navigator and recreate the pages with a new page A.
But what happens in this moment is that Navigator reuses the same Page A that existed before and only updates its state and properties (of the widget).
I tried overriding the method canUpdate on Page (below) in order to tell that page that now it should be rebuild, but the issue is that the Page class is immutable, so it complains that I can't have a non-final variable on it.
class CustomPage<T> extends Page<T> {
final Widget child;
bool _pageCanBeUpdated = true;
CustomPage({#required this.child, Key key}) : super(key: key);
#override
Route<T> createRoute(BuildContext context) {
return MaterialPageRoute(
builder: (context) => child,
settings: this,
);
}
void shouldCleanPage() {
_pageCanBeUpdated = false;
}
#override
bool canUpdate(Page other) {
return _pageCanBeUpdated && super.canUpdate(other);
}
}

Answer 1

I was able to solve it in another way. Instead of overriding the canUpdate method, I created a different key for the page.
In my RouterDelegate I keep a "salt" variable as int _salt and whenever I need to clean the whole stack of pages, I increment this salt and add append to the key. This way it is different until the next time I have to recreate it all.
Salt: int _salt = 0;
Initially: [Page(ValueKey('home $_salt')), Page(ValueKey('invites $_salt'))]
Clean pages: []
Increment salt: _salt++
Recreate page with [Page(ValueKey('home $_salt')
It forces the recreation of the whole page instead of reusing the ones that already exist.
