The error message suggests that there is a conflict between the version of @react-native-firebase/app that you have installed and the version required by @react-native-firebase/crashlytics.
To fix this, you can try upgrading the version of @react-native-firebase/app to 17.3.2 to match the version required by @react-native-firebase/crashlytics.
Update your package.json file to include the following:
"dependencies": {
"@react-native-firebase/app": "17.3.2",
"@react-native-firebase/auth": "^16.5.0",
"@react-native-firebase/messaging": "^16.5.0",
"@react-native-firebase/crashlytics": "*",
"react-native": "0.68.5"
}
Then run npm install again to install the updated dependencies.
If this doesn't work, you can try using the --force or --legacy-peer-deps flags as suggested in the error message. However, be aware that this may result in an incorrect or broken dependency resolution.
