Expo. Likely fix, 7 October 2026.

Versions: Expo SDK 57, expo-router 57.0.24

Error:

```
Install the 'react-native-tab-view' package
```

## Cause

Material top tabs need two extra packages, one of them native.

## Fix

`npx expo install react-native-tab-view react-native-pager-view`, then make a new dev build (pager-view is native).
