FlutterTimeGuard is a Flutter plugin designed to detect manual changes to device date, time, or timezone settings. It validates the device clock against NTP (Network Time Protocol) servers to ensure accuracy and integrity. This package is particularly useful in security-sensitive applications where accurate timekeeping is critical, such as authentication systems, session management, or fraud detection. By preventing clock-tampering, it helps maintain trust in time-based operations.
