Stack Navigator Goes Back to Previous Screen if Route Matches, Even if Params Are Different on v2

[Nicell]

Which package manager are you using? (Yarn is recommended)

yarn

Summary

As of SDK 49 and expo-router v2, when a stack has links pressed on in the following order:

• /Nick (/[user])
• /two (/two)
• /Joe (/[user])

The stack navigator goes back to the /Nick screen when the /Joe link is pressed on the /two page instead of pushing a new screen onto the stack. This behavior does not happen before upgrading. While it does update the params, I was not expecting search params to update for screens, so my app doesn't handle it, and I don't want it to reuse screens. Continually pushing on the stack is better for my app's UX, and I'm not sure if it's achievable with the new update.

Minimal reproducible example

I was able to create a workaround by setting the getId prop on the Stack.Screens. See https://github.com/react-navigation/react-navigation/issues/9090

Still not sure why this behavior showed up with SDK 49 specifically.

I wasn't able to reproduce all the screens were pushed as expected, with no popping.

@EvanBacon Here's a video of my minimal reproducible example in the latest Expo Go on an iPhone simulator. All I did was yarn start, open on the simulator, and press each link.

for those who facing the same issue use following code

<Stack.Screen getId={({ params }) => params.id} name="user/[id]" />

getID function makes it work

dont forget to spread params
