Get First Character in String

To get first character in the given string in Dart, we can access the character in the string at index 0 using square bracket notation.

The syntax of expression to get the first character in the string myString is

myString[0]

Dart Program

In the following program, we take a string 'apple' in variable myString, and get the first character in this string.

main.dart

void main() {
    var myString = 'apple';

    if (myString.length > 0) {
      var output = myString[0];
      print('First character : $output');
    } else {
      print('Empty string, please check.');
    }
}

Output

In the program, before accessing the character at index=0, we have checked if the string is not empty, so that when accessing the character we do not get any error.
