TOTP class
TOTP class will generate the OTP (One Time Password) object with the current or given time.
Constructors
- TOTP({required String secret, int digits = 6, int interval = 30, OTPAlgorithm algorithm = OTPAlgorithm.SHA1})
- This constructor will create an TOTP instance.
Properties
- algorithm ↔ OTPAlgorithm
-
The crypto algorithm used on HMAC encoding.

Methods
-
generateOTP(
{required int input, OTPAlgorithm? algorithm}) → String -
When class HOTP or TOTP pass the input params to this
function, it will generate the OTP object with params,
the params may be counter or time.
inherited
-
generateUrl(
{String? issuer, String? account}) → String -
Generate a url with OTP instance.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
now(
) → String - Generate the TOTP value with current time.
-
toString(
) → String -
A string representation of this object.
inherited
-
value(
{DateTime? date}) → String? - Generate the OTP with a custom time.
-
verify(
{String? otp, DateTime? time}) → bool - Verifies the TOTP value passed in against the current time.
