Functions
-
checkMask(String mask)
→ void
-
-
checkNumberByLuhn({required String number})
→ bool
-
-
formatAsCardNumber(String cardNumber)
→ String
-
-
formatAsPhoneNumber(String phone, {InvalidPhoneAction invalidPhoneAction = InvalidPhoneAction.ShowUnformatted, bool allowEndlessPhone = false, String? defaultMask, String? defaultCountryCode})
→ String?
-
allowEndlessPhone if this is true,
the
-
getCardSystemData(String cardNumber)
→ CardSystemData?
-
-
getCountryDatasByPhone(String phone)
→ List<PhoneCountryData>
-
returns a list of country datas with a country code of
the supplied phone number. The return type is List because
many countries and territories may share the same phone code
the list will contain one PhoneCountryData at max
returns A list of PhoneCountryData datas or an empty list
-
isCardNumberValid({required String cardNumber, bool checkLength = false, bool useLuhnAlgo = true})
→ bool
-
useLuhnAlgo validates the number using the Luhn algorithm
-
isCardValidNumber(String cardNumber, {bool checkLength = false})
→ bool
-
checks not only for a length and characters but also
for card system code. If it's not found the succession of numbers
will not be marked as a valid card number
-
isCryptoCurrency(String currencyId)
→ bool
-
Basically it doesn't really check if the currencyId is
a crypto currency. It just checks if it's not fiat.
I decided not to collect all possible crypto currecies as
there's an endless amount of them
-
isDigit(String? character, {bool positiveOnly = false})
→ bool
-
character a character to check if it's a digit against
positiveOnly if true it will not allow a minus (dash) character
to be accepted as a part of a digit
-
isFiatCurrency(String currencyId)
→ bool
-
Checks if currency is fiat
-
isPhoneValid(String phone, {bool allowEndlessPhone = false, String? defaultCountryCode})
→ bool
-
-
isUnmaskableSymbol(String? symbol)
→ bool
-
-
numericStringStartsWithOrphanPeriod(String string)
→ bool
-
-
toCurrencyString(String value, {int mantissaLength = 2, ThousandSeparator thousandSeparator = ThousandSeparator.Comma, ShorteningPolicy shorteningPolicy = ShorteningPolicy.NoShortening, String leadingSymbol = '', String trailingSymbol = '', bool useSymbolPadding = false, bool isRawValue = false})
→ String
-
isRawValue pass true if you
-
toNumericString(String? inputString, {bool allowPeriod = false, bool allowHyphen = true, String mantissaSeparator = '.', String? errorText, bool allowAllZeroes = false, int? mantissaLength})
→ String
-
errorText if you don't want this method to throw any
errors, pass null here
allowAllZeroes might be useful e.g. for phone masks
-
toNumericStringByRegex(String? inputString, {bool allowPeriod = false, bool allowHyphen = true})
→ String
-
