How To Shuffle List In Flutter – Easy Flutter Code Examples

shuffle list in flutter

In this tutorial, we’ll learn how to shuffle list in Flutter. We’ll be using multiple Flutter code examples to understand it practically.

After reading this post, you’ll have a detailed practical knowledge of how to properly shuffle list in Flutter.

So without any delay, let’s just throw ourselves right into its practical implementation.

Introduction: Shuffle List In Flutter

It specifies a process through which we can change the order of list items randomly. We have to use shuffle() method in order to perform this action.

Let’s now understand it practically using multiple code examples.

Syntax of Shuffle Method

listName.shuffle()

We’ve to use the shuffle() method like this.

Implement Shuffle List In Flutter (Easy Code Examples)

See below examples to understand the usage/role of shuffle() method in Flutter list.

Example 1: Shuffle List In Flutter

Let’s first create a list in Flutter. After that, we’ll apply shuffle() method on it. See below code:

List listOfValues=[1,2,4,3];
listOfValues.shuffle();  // shuffle the list
print(listOfValues);

Output

[3, 4, 1, 2]   // list items has been shuffled
[3, 2, 1, 4]   // running the code again will also shuffle the list again

You will get an updated shuffled list each time you run the code. You can apply shuffle method to list again and again by using this listName.shuffle() statement.

Example 2: shuffle() Method Updates the Existing List

This method does not return anything. It just update/shuffle the current list. See below code:

List listOfValues=['green',3.4,4,2,5,6,34.78];
listOfValues.shuffle();   // shuffles the existing list
print(listOfValues);

Output

[34.78, 3.4, 2, green, 5, 6, 4]

So this is how we can properly shuffle list in Flutter. Hope you have learned alot from this  Flutter tutorial. Do use this method in your own Flutter code and share your experience with us and also with other Flutter developers.

Conclusion

To conclude this post, hope you now have a proper and detailed practical knowledge of how to shuffle list in Flutter.
