In this tutorial, we will create a simple utility class in Dart to generate random Indonesian names. This can be useful for testing applications, generating dummy user data, or simulating user input in your Flutter project.
Step 1: Creating the UtilFaker Class
Create a new Dart file named util_faker.dart inside the lib folder of your Flutter project. Then, define the class as follows:
Explanation:
-
We define a private list _indonesianNames containing sample Indonesian names.
-
The randomName getter selects a random name from the list using the Random class from dart:math.
Step 2: Using UtilFaker in Your Flutter Project
Now that we have our faker utility class, let’s use it inside a Flutter widget.
Example: Displaying a Random Name in a Flutter App
Open your main.dart file and update it with the following code:
What This Code Does:
-
It displays a randomly generated Indonesian name when the app starts.
-
When the button is pressed, a new name is generated and displayed.
Where to Use This Faker Class
The UtilFaker class can be used in various scenarios, such as:
-
Testing: Generate random names for UI testing without needing a real database.
-
Prototyping: Fill in dummy user profiles while designing a UI.
-
Game Development: Assign random character names in a game.
-
Mock APIs: Simulate API responses with randomly generated names.
Conclusion
In this tutorial, we created a simple name faker utility in Dart and integrated it into a Flutter application. You can expand this class by adding more names or generating full names instead of just first names.
