Methods

addDaysOrMore(DateTime dateTime, {int days = 0, int months = 0, int years = 0}) → DateTime

adds a Duration that is more that 24 hours this works with time shifts like daylight saving time

addMonthsWithoutOverflow(int months, DateTime date) → DateTime

Adds months to the date with no day overflow in the next month.

clearTime(DateTime dateTime) → DateTime

Removes any local time from the given dateTime by converting the given utc date time to local, removing the time part and converting back to utc.

createContentDisposition(String filename) → String

Creates a proper Content-Disposition header value with UTF-8 encoded filename

dateDifference(DateTime? first, DateTime? second) → Duration

Use this function instead of DateTime.difference!

dateTimeIncludeTime(DateTime dateTime) → bool

Returns true if the given dateTime includes a time.

formatDate(DateTime? dateTime, {String locale = 'de', String? format}) → String

Return a string representing dateTime in the German or English date format or another given format.

formatTime(DateTime? dateTime, {String? format}) → String

Return a string representing dateTime in the German time format or another given format.

getDateAtDayOfCurrentMonth(int day) → DateTime

Returns the DateTime at the day of the current month.

getDateAtDayOfMonth(int day, DateTime month) → DateTime

Returns the DateTime at the day in the month, with no day overflow.

getValueByPath(Map<String, dynamic> object, String path) → dynamic

Get the value of a map by path. The path is a dot-separated path of keys, which may be escaped with backticks.

localNow({int? year, int? month, int? day, int? hour, int? minute, int? second, int? millisecond, int? microsecond, bool minuteGranularity = false}) → DateTime

Returns the current date and time in the local timezone.

localToday() → DateTime

Returns the current date in the local timezone.

localToUtc(DateTime dateTime) → DateTime

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

numToString(num number, {bool thousandsSeparator = false, int wholeDigitCount = 1, int decimalDigitCount = 2, bool padDecimalDigits = false, String locale = 'de-DE', String? unit}) → String

Formats a number to a string. The number is rounded to decimalDigitCount decimal places and optionally padded with zeros if padDecimalDigits is true. If thousandsSeparator is true, the number is formatted with a thousands separator. Use locale to specify the thousands separator and decimal separator. The number is padded with zeros to the left to reach at least wholeDigitCount whole digits.

preserveKeysInMap(Map<String, dynamic> object, List<String> keys) → void

Clean a map, except of some keys.

randomString({int length = 8, bool includeCapitalLetters = true}) → String

Returns a random String with a specific length.

removeKeysFromMap(Map<String, dynamic> object, List<String> keys) → void

Remove multiple keys from a map.

roundToDecimalPlaces(num value, [int fractionalDigits = 8]) → double

Rounds a number to the given amount of decimal places

searchString({required List<String> strings, required String searchString, bool ignoreCase = true, bool reorder = true}) → List<int>

Returns a list of indexes of the found strings. The search looks for strings that contain the search searchString.

stringToNumber(String text, {int? precision, String locale = 'de-DE'}) → num?

Parse a string to a number. If precision is null, the number is parsed as is. If precision is 0, the number is rounded to the nearest integer. If precision is given, the number is rounded to exactly precision decimal places. Use locale to specify the thousands separator and decimal separator.

toQuotedFieldPath(String? fieldPath) → String?

Returns a quoted field path.

toString() → String

A string representation of this object.

inherited

tryLocalToUtc(DateTime? dateTime) → DateTime?

tryUtcToLocal(DateTime? dateTime) → DateTime?

utcNow({int? year, int? month, int? day, int? hour, int? minute, int? second, int? millisecond, int? microsecond}) → DateTime

Returns the current date and time in UTC.

utcToLocal(DateTime dateTime) → DateTime

Operators

operator ==(Object other) → bool

The equality operator.
