replaceLastName with nested navigation #153

Open BarashkovaElena opened 2 months ago

BarashkovaElena commented 2 months ago

I cannot figure out how to make replaceLastName work with nested navigation, need some help on that. There is a root navigator and a a nested navigator. I want to open a page inside a tab in the nested navigator and then replace it with another page. I perform the following steps:

  1. Open nested navigation page. Stack tree initially looks like this: 
    
Key [-1] (Root)
Key [2] (bottom_bar_page)

Key [20] (bottom_bar_page) Key [3] (home)

2. Open nested page over the home tab. Stack tree becomes this:

Key [-1] (Root) Key [2] (bottom_bar_page)

Key [20] (bottom_bar_page) Key [3] (home) Key [4] (internal)

3. Call QR.navigatorOf(bottomBarPageName).replaceLastName(dtoPageName);
Stack tree becomes this:

Key [-1] (Root) Key [2] (bottom_bar_page)

Key [20] (bottom_bar_page) Key [4] (internal) Key [3] (home) Key [6] (dto)


This is not correct, because "internal" page should not be in the stack. It should contain only "home" and "dto".
I need to get this stack:

Key [-1] (Root) Key [2] (bottom_bar_page)

Key [20] (bottom_bar_page) Key [3] (home) Key [6] (dto)


If I call replaceLastNamed on the root navigation, then the app crashes:

How to get the desired stack tree?
