List.isEmpty is a quick and easy way to check if a list is empty in Flutter. If the list is empty, it will return true, otherwise, it will return false. This is a handy tool to use when checking for data before performing an action on it.
Syntax
List.isEmpty
Code example
List myList = ['John', 'Sandy', 'Truce'];
if(myList.isEmpty) {
print("List is empty");
} else {
print("List is not empty");
}
Output
List is not empty
The code above is a simple example of how to check if a list is empty or not. If the list is empty, the code will print "List is empty". If the list is not empty, the code will print "List is not empty".
We can also use List.length in Dart to check if a list is empty. This will return 0 if the list is empty. We can understand it using the below code example.
List myList = [];
if(myList.length == 0) {
print('The list is empty');
}
Output
The list is empty
