Securing API keys in shared codebases is crucial to protect sensitive information and prevent unauthorized access. You can achieve this by using environment variables, secure storage, or obfuscation techniques appropriate for your mobile development framework.

Example Concept: In mobile applications, API keys should never be hardcoded into the source code. Instead, use environment-specific configuration files or secure storage solutions provided by the platform. For instance, in iOS, you can use the Keychain to store sensitive information securely, while in Android, the Keystore system is recommended. Additionally, consider using build scripts to inject API keys at compile time, ensuring they are not exposed in the source code.

Additional Comment:

For React Native, use libraries like react-native-dotenv to manage environment variables securely.
In Flutter, consider using the flutter_secure_storage package for storing sensitive data.
Always review and follow best practices for securing API keys as recommended by the API provider.
Regularly rotate API keys and monitor their usage to detect any unauthorized access.
