If the string contains leading or trailing whitespace, a new string with no leading and no trailing whitespace is returned: ```dart final trimmed = '\tDart is fun\n'.trim(); print(trimmed); 'Dart is fun' ``` Otherwise, the original string itself is returned: ```dart const string1 = 'Dart'; final string2 = string1.trim(); 'Dart' print(identical(string1, string2)); true ``` Whitespace is defined by the Unicode White_Space property (as defined in version 6.2 or later) and the BOM character, 0xFEFF.
