Static Methods

abbreviate(String str, int maxWidth, {int offset = 0}) → String: Abbreviate a string to maxWidth by truncating the string and adding '...' to then truncated string.
equals(String? lhs, String? rhs) → bool: Safely compares two strings. If both are null returns true If one of them is null returns false if both are the same returns true.
isBlank(String? value) → bool: true if the value is null or Blank. Whitespace is ignored See: isEmpty to check for a zero length string.
isEmpty(String? value) → bool: true if the value is null, or is a zero length String
isNotBlank(String? value) → bool: true if the value is not null and not Blank. A string containing only whitespace is considered blank. See: isNotEmpty to check for non-zero length string.
isNotEmpty(String? value) → bool: true if the value is not null and is not a zero length String
isNumeric(String? string) → bool: Checks if string is a number by attempting to parse it as a double. INFINITY and NaN are not treated as numbers.
left(String value, int fromLeft) → String: Returns the first fromLeft characters from value If fromLeft is longer than value then an RangeError is thrown.
nullToEmpty(String? value) → String: If value is null we return an zero length string otherwise we return value.
orElse(String? value, String elseValue) → String: If value is null the elseValue is returned otherwise value is returned.
properCase(String sentence) → String: Converts sentence to proper case by capitalising the first letter of each word and forcing all other characters to lower case.
right(String value, int fromRight) → String: Returns all characters from value starting at fromRight inclusive. If fromRight is outside the bounds of value then an RangeError is thrown.
