ProGuard on Flutter using 3rd party packages

Is it necessary to use proguard on your flutter app?

I'm trying to secure my app and the only one things I know is to handle the user data using flutter_secure_storage. I want a maximum security of my application.

Firstly you should understand what proguard is and what it can do.

Short description: it is a tool for code shrinking, obfuscation, and optimization in Android development. When you build a Flutter app for Android, you can use ProGuard to reduce the size of your app's APK and make it harder for reverse-engineers to understand your code.

For Security purpose other than data, you should keep this in mind.

  1. Use HTTPS: Use HTTPS to encrypt data transmitted between your app and your server to prevent eavesdropping and data tampering.
  2. Implement encryption: Use encryption algorithms such as AES or RSA to protect sensitive data, such as passwords or credit card details, stored on the device.
  3. Use authentication and authorization: Implement user authentication and authorization mechanisms to prevent unauthorized access to your app's data and functionalities.
  4. Use code obfuscation: Use code obfuscation tools like ProGuard or R8 to make it harder for attackers to reverse-engineer your app's code.
  5. Implement secure coding practices: Follow secure coding practices such as avoiding hardcoding sensitive data in the app's code, validating user inputs, and avoiding third-party libraries with known security vulnerabilities.

Implementing these measures can help you achieve maximum security for your Flutter app. However, keep in mind that security is a continuous process, and you should regularly review and update your security measures to keep up with evolving security threats.
