canAuthenticate method

Future<bool> canAuthenticate()

Checks whether biometric authentication is supported on the device.

This method queries the device's capabilities to determine whether biometric authentication methods, such as fingerprint or face recognition, are available and supported. It returns true if biometric authentication is supported, and false otherwise.

Note: The availability of biometric authentication can vary by device and platform, and the user must have set up biometrics in their device settings for this method to return true.

Returns true if biometric authentication is supported, false otherwise.

Example usage:

bool isBiometricSupported = await canAuthenticate();
if (isBiometricSupported) {
  // Display biometric authentication option
} else {
  // Provide an alternative authentication method
}

Throws an exception if there's an issue checking the device's support for biometric authentication.
