I want to compare two characters. Something like this:
if ('a' > 'b')
However, the above code is comparing two strings.
How do I do this in Dart?

How do you compare two lists in darts? Check if two Lists are Equal Element Wise We shall write a function areListsEqual() to check if the given two lists are equal element by element. As a pre-requisite, we check if both the given variables are lists, and then compare their lengths. list1 and list2 are equal.
We can also check whether two strings are equal by == operator. It compares every element of the first string with every element of the second string.
First convert both of the strings to lowercase and then compare them both. Use toLowerCase() function for both of the strings. Save this answer.
Example 1 — Compare 2 students without overriding operator == : * The equality operator. * only if `this` and [other] are the same object. external bool operator ==(other);
String in Dart implements the Comparable interface. You can use compareTo to compare them.
String a = 'a';
String b = 'b';
String c = 'a';
print('value: ${a.compareTo(b)}'); // prints "value: -1"
print('value: ${a.compareTo(c)}'); // prints "value: 0"
print('value: ${b.compareTo(a)}'); // prints "value: 1"
Dart doesn't have a 'char' or 'character' type. You can get the UTF-16 character code from any point in a string, and compare that.
Use codeUnitAt to get the actual character code from a string.
if ('a'.codeUnitAt(0) > 'b'.codeUnitAt(0))
See the codeUnitAt docs: https://api.dartlang.org/docs/channels/stable/latest/dart_core/String.html#codeUnitAt
