As we discussed earlier, Dart String is a sequence of characters, letters, numbers, and unique characters. It is the sequence of UTF – 16 Unicode characters where Dart Runes are the sequence UTF – 32 Unicode code points. It is a UTF-32 string which is used to print the special symbol. For example – The theta (\u0398) symbol is signified by using the corresponding Unicode equivalent \\u0398; here ‘\\u’ refers to Unicode, and the numbers are in the hexadecimal. Sometimes the hex digits are the more than 4 digits then it should be placed in curly brackets ({}). Let’s understand it by the following example.<\/p>\n\n\n\n
Example –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n The Dart provides the\u00a0dart: core<\/strong>\u00a0library which has the\u00a0Dart\u00a0Runes. The String code unit can be retrieved in the following three methods.<\/p>\n\n\n\n We can access the character’s code unit in the given string by using the codeUnitAt()<\/strong> method. It accepts the index position as an argument and returns the 16-bit UTF-16 code unit at the passed index position of the string. The syntax is the given below.<\/p>\n\n\n\n Syntax –<\/strong><\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n Explanation –<\/strong><\/p>\n\n\n\n In the above code, the variable str<\/strong> holds string value “JavaTpoint”. We called the codeuUnitAt() function and passed index position. It returned the code unit of 0th<\/sup> index character.<\/p>\n\n\n\n The codeUnits property returns UTF-16 code units for given string in the form of a list. The syntax is given below.<\/p>\n\n\n\n Syntax –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Let’s have a look at following example –<\/p>\n\n\n\n Example –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n Explanation –<\/strong><\/p>\n\n\n\n The codeUnits returned the list of the code unit corresponding to the given character.<\/p>\n\n\n\n The runes property is used to iterate the given string though the UTF-16 code unit. The Syntax is given below.<\/p>\n\n\n\n Syntax –<\/strong><\/a><\/a><\/a><\/p>\n\n\n\n Consider the following example.<\/p>\n\n\n\n Example –<\/strong><\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n As we discussed earlier, Dart String is a sequence of characters, letters, numbers, and unique characters.
