Native Stack Navigator combining headerTransparent headerBlurEffect and headerShadowVisible does not work correctly on iOS

[jobpaardekooper]

Current behavior

Using screenOptions for the stack navigator on iOS as follows:

{
    headerTransparent: true,
    headerBlurEffect: 'systemMaterial',
    headerShadowVisible: true,
}

Does not display the line on the bottom of the header on iOS.

Expected behavior

There should be a way to achieve the same header behavior as the iOS settings app where there is a blured background and gray line at the bottom. Here is a screenshot of the iOS settings header:

Hey @jobpaardekooper! Thanks for opening the issue. It seems that the issue doesn't contain a link to a repro.

The best way to get attention to your issue is to provide an easy way for a developer to reproduce the issue.

You can provide a repro using any of the following:

• Expo Snack
• TypeScript Playground
• GitHub repo under your username

A snack link is preferred since it's the easiest way to both create and share a repro. If it's not possible to create a repro using a snack, link to a GitHub repo under your username is a good alternative. Don't link to a branch or specific file etc. as it won't be detected.

Try to keep the repro as small as possible by narrowing down the minimal amount of code needed to reproduce the issue. Don't link to your entire project or a project containing code unrelated to the issue. See "How to create a Minimal, Reproducible Example" for more information.

You can edit your original issue to include a link to the repro, or leave it as a comment. The issue will be closed automatically after a while if you don't provide a repro.

Having a bot like this is not very productive...

I know it takes a bunch of time to go trough issues and I should really add a reproduction repo but, like the reviewers of these issues, I am also busy. This is not a super big critical issue so it is not such a big deal that it is not fixed but it is nice to have an issue that at least documents the problem is there.

@jobpaardekooper having the same issue.
Did you manage to fix it ?

[jobpaardekooper]

No I did not fix it.

[smontlouis]

Found a workaround:

headerStyle: {
            backgroundColor:
                colorScheme === 'dark'
                  ? 'rgba(0,0,0,0.05)'
                  : 'rgba(255,255,255,0.05)'
          },

Instead of headerTransparent: true
