Most of the react navigation examples on snack are not working

Most of the react navigation examples are not working.
They all say:
package.json (6:5)
Failed to resolve dependency 'react-native-pager-view@6.1.2' (Invalid module ../Utilities/Platform - Module not found: Error: Can't resolve '../Utilities/Platform' in '/tmp/snackager/snackager/buildStatus/1/react-native-pager-view@6.1.2-ios,android,web/package/node_modules/react-native/Libraries/Alert')

Something have to fix on your side?

For example here is one of the examples:
https://snack.expo.io/?platform=android&name=header%20button&dependencies=%40expo%2Fvector-icons%40*%2C%40react-native-community%2Fmasked-view%40*%2Creact-native-gesture-handler%40*%2Creact-native-pager-view%40*%2Creact-native-paper%40%5E4.7.2%2Creact-native-reanimated%40*%2Creact-native-safe-area-context%40*%2Creact-native-screens%40*%2Creact-native-tab-view%40%5E3.0.0%2C%40react-navigation%2Fbottom-tabs%406.3.1%2C%40react-navigation%2Fdrawer%406.4.1%2C%40react-navigation%2Felements%401.3.3%2C%40react-navigation%2Fmaterial-bottom-tabs%406.2.1%2C%40react-navigation%2Fmaterial-top-tabs%406.2.1%2C%40react-navigation%2Fnative-stack%406.6.1%2C%40react-navigation%2Fnative%406.0.10%2C%40react-navigation%2Fstack%406.2.1&hideQueryParams=true&sourceUrl=https%3A%2F%2Freactnavigation.org%2Fexamples%2F6.x%2Fsimple-header-button.js

Hi @armyofda12mnkeys

Yes, it looks to me like there are extra dependencies specified in package.json that don't need to be there are are causing problems.

e.g. if I try the link you posted above, it only has the following imports:

import * as React from 'react';
import { View, Text, Button, Image } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';

By the way, the first one (the 'react' import) is no longer needed and can just be deleted.

If you check package.json it has all of these dependencies specified:

  "dependencies": {
    "@expo/vector-icons": "^13.0.0",
    "@react-native-community/masked-view": "*",
    "react-native-gesture-handler": "~2.9.0",
    "react-native-pager-view": "6.1.2",
    "react-native-paper": "^4.7.2",
    "react-native-reanimated": "~2.14.4",
    "react-native-safe-area-context": "4.5.0",
    "react-native-screens": "~3.20.0",
    "react-native-tab-view": "^3.0.0",
    "@react-navigation/bottom-tabs": "6.3.1",
    "@react-navigation/drawer": "6.4.1",
    "@react-navigation/elements": "1.3.3",
    "@react-navigation/material-bottom-tabs": "6.2.1",
    "@react-navigation/material-top-tabs": "6.2.1",
    "@react-navigation/native-stack": "6.6.1",
    "@react-navigation/native": "6.0.10",
    "@react-navigation/stack": "6.2.1"
  }

In Snack it does not list things like expo or react-native. They are automatically included based on the selected Expo SDK version.

The following should fix this Snack: Remove everything from dependencies except the stuff you're actually importing:

  "dependencies": {
    "@react-navigation/native-stack": "6.6.1",
    "@react-navigation/native": "6.0.10"
  }

Snack will then prompt you to add back a few things and you'll end up with this:

  "dependencies": {
    "@react-navigation/native": "6.0.10",
    "@react-navigation/native-stack": "6.6.1",
    "react-native-safe-area-context": "4.5.0",
    "react-native-screens": "~3.20.0"
  }

If I do that it works for me.

@satya164 I think this issue can be closed since you and Cedric fixed the examples
