ascii of a character in dart

// Grab a substring.
assert('Never odd or even'.substring(6, 9) == 'odd');

// Split a string using a string pattern.
var parts = 'structured web apps'.split(' ');
assert(parts.length == 3);
assert(parts[0] == 'structured');

// Get a UTF-16 code unit (as a string) by index.
assert('Never odd or even'[0] == 'N');

// Use split() with an empty string parameter to get
// a list of all characters (as Strings); good for
// iterating.

  print(char);
}

// Get all the UTF-16 code units in the string.
var codeUnitList =
    'Never odd or even'.codeUnits.toList();
