Unicode :-
In Dart, Unicode characters can be represented using escape sequences or directly.
Using Escape Sequences: Dart supports escape sequences for representing Unicode characters. For example:
void main() {
print('\u{1F44B}'); // Prints a waving hand emoji
}
insert char in unicode
ex:
void main() {
String myString = 'Hello, Jeet this is a star: \u{1F31F}';
print(myString);
}
