I don't see Dart strings treated as lists of characters. I assume I have to use for loops, which would be lame.

To iterate over a string, character by character, call runes on given string which returns a Runes object. Use forEach() method on this Runes object, which lets us iterate over each code point in the string, where code point is a character.
To find the substring of a string in Dart, call substring() method on the String and pass the starting position and ending position of the substring in this string, as arguments.
To check if a string contains other string in Dart, call contains() method on this string and pass the other string as argument. contains() method returns returns a boolean value of true if this string contains the other string, or false if the this string does not contain other string.
A rune is an integer representing a Unicode code point. The String class in the dart:core library provides mechanisms to access runes. String code units / runes can be accessed in three ways − Using String.codeUnitAt() function.
An alternative implementation (working with characters outside the basic multilingual plane):
"A string".runes.forEach((int rune) { var character=new String.fromCharCode(rune); print(character); }); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
