How to get Length of String in Dart ?

Answer

To get the length of a given string in Dart, you can use the length property of the String class.

✐ Examples

1 Length of "Hello World" String

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use the length property of the string object str1 to get the length of the string and store the returned value in the variable length1.
The length property returns the length of this string.
Finally, we print the value in length1 to the console using print().

Dart Program

// Length of "Hello World" String
void main() {
  var str1 = "Hello World";
  var length1 = str1.length;
  print("Length of given string is: $length1");
}

Output

Length of given string is: 11

2 Length of "apple" String

In this example,

We create a variable named str2 with a string value of "apple".
We then use the length property of the string object str2 to get the length of the string and store the returned value in the variable length2.
The length property returns the length of this string.
Finally, we print the value in length2 to the console using print().

Dart Program

// Length of "apple" String
void main() {
  var str2 = "apple";
  var length2 = str2.length;
  print("Length of given string is: $length2");
}

Output

Length of given string is: 5
