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.
Example 1:
Dart
// main function start void main() {
// initialise a string st
String? st = "" ;
// print string is empty or not
print(st.isEmpty);
} |
Output:
true
Example 2:
Dart
// main function start void main() {
// initialise a string st
String? st = "Geeksforgeeks" ;
// print string is empty or not
print(st.isEmpty);
} |
Output:
false
