List in Dart is a collection of objects. The duplicate entry in a list is also allowed.
This article shows how to find the length of a list in Dart.
The property named length is used to get the number of objects in a list.
The list can be classified as −
- Fixed Length List
- A list whose length cannot be changed at runtime is known as a fixed-length list.
- Growable List
- A list whose length can change at runtime is known as a growable list.
A list is simply an ordered and mutable group of objects.
Starting index of the list is 0(zero) through length - 1.
The length property
The list in Dart provides a property length that returns the total objects within a list.
Syntax
listName.lengthThe length property gives an integer value i.e the number of objects within the list.
Example
void main()
{
var countries = ["India 🇮🇳", "Switzerland 🇨🇭", 1, -9.5, 0, 1];
print(countries);
print('Total elements : ${countries.length}');
}Output:
[India 🇮🇳, Switzerland 🇨🇭, 1, -9.5, 0, 1]
Total elements : 6The list has 6 elements.
Another way to get the length of a list is by using looping structure but the more preferable way is to use the length property of a list.
Conclusion
To find the length of a list in Dart, use the length property of a list.
