Document the fix for header buttons flashing on mount when using unstable_headerLeftItems/unstable_headerRightItems with NativeTabs. The workaround uses type: 'custom' with hidesSharedBackground: true and a custom styled wrapper. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

| 2. **Headers missing**: Nest a Stack inside each tab group | ||
| 3. **Trigger name mismatch**: Ensure `name` matches exact route name including parentheses | ||
| 4. **Badge not visible**: Badge must be a child of Trigger, not a prop | ||
| 5. **Header button flash**: When using `unstable_headerLeftItems`/`unstable_headerRightItems`, buttons may flash on mount. Fix by using `type: 'custom'` with `hidesSharedBackground: true` and a custom styled wrapper: |

The preferred API for header buttons is:
<Stack.Toolbar placement="left">
<Stack.Toolbar.Button icon="gear" onPress={() => router.push('/settings')} hidesSharedBackground/>
</Stack.Toolbar>This uses the native UIBarButtonItem which doesn't flicker. It also doesn't support Android or web yet :[

If you want to use custom views something like this should work
<Stack.Toolbar placement="left">
<Stack.Toolbar.View hidesSharedBackground>
<Pressable
style={{ width: 24, height: 24 }}
onPress={() => router.push("/settings")}
>
<SymbolView name="gear" />
</Pressable>
</Stack.Toolbar.View>
</Stack.Toolbar>However I think that the proper solution here would be wrapping the app with <ThemeProvider
I added a PR which covers this and other common issues - #16
