Build a secure mobile banking app with Flutter

Creating secure mobile banking apps with Flutter involves several key practices to ensure data protection and user privacy. The article outlines the use of HTTPS for secure communication between the app and backend servers, emphasizing the necessity of trusted certificates for verifying endpoints. It discusses the secure storage of data on devices using packages like `flutter_secure_storage`, `biometric_storage`, and Hive, each offering different levels of encryption and biometric protection for sensitive information. Additionally, it highlights the importance of using biometric authentication to restrict app access and the use of overlays to hide sensitive information when the app is not in the foreground. These practices are supported by readily available Flutter packages, making it easier for developers to integrate robust security features into their applications.
