How to Append a Character to end of a String in Dart ?

Answer

To append a character to the end of a string in Dart, you can use string interpolation or the + operator.

✐ Examples

1 Append '!' to "Hello World"

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use string interpolation to append the character '!' to str1.
Finally, we print the modified string to the console.

Dart Program

void main() {
  var str1 = 'Hello World';
  str1 += '!';
  print(str1);
}

Output

Hello World!

2 Append '?' to "How are you"

In this example,

We create a variable named str2 with a string value of "How are you".
We then use the + operator to append the character '?' to str2.
Finally, we print the modified string to the console.

Dart Program

void main() {
  var str2 = 'How are you';
  str2 += '?';
  print(str2);
}

Output

How are you?
