We can check a string is empty or not by the String Property isEmpty. If the string is empty then it returns True if the string is not empty then it returns False.
Syntax:
String.isEmpty - Return : True or False.
Image Representation:
Example 1:
// main function start
void main() {
// initialise a string st
String? st = "";
// print string is empty or not
print(st.isEmpty);
}
Output:
true
Example 2:
// main function start
void main() {
// initialise a string st
String? st = "Geeksforgeeks";
// print string is empty or not
print(st.isEmpty);
}
Output:
