will be used.

Link native dependency or all native dependencies if no packageName
passed.
--platforms [list]

uninstall
Usage:
react-native uninstall <packageName>
Unlinks single package native dependencies and then uninstalls it from package.json
. If uninstall
detects yarn.lock
in your project, it will use Yarn as package manager. Otherwise npm
will be used.
unlink
Usage:
react-native unlink <packageName>
Unlink native dependency linked with the link
command.
upgrade
Usage:
react-native upgrade [npm-version]
Upgrade your app's template files to the specified or latest npm version using rn-diff-purge project. Only valid semver versions are allowed.
Using this command is a recommended way of upgrading relatively simple React Native apps with not too many native libraries linked. The more iOS and Android build files are modified, the higher chance for a conflicts. The command will guide you on how to continue upgrade process manually in case of failure.
Note: If you'd like to upgrade using this method from React Native version lower than 0.59.0, you may use a standalone version of this CLI: npx @react-native-community/cli upgrade
.
