mock_data

Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The mock_data package generates random, realistic test data in Dart. It provides utilities to create random strings, integers, names, colors, IP addresses, UUIDs, URLs, and dates, making it ideal for simulating real-world data during development and testing. The package is lightweight and easy to integrate, supporting all major platforms including Android, iOS, Web, macOS, Windows, and Linux. It's particularly useful for populating UIs with placeholder content or testing data-handling logic without relying on external sources.

Use cases

Populating UI prototypes with sample data
Testing data parsing and display logic
Generating fake user profiles
Simulating API responses
Creating randomized test datasets
Filling forms with dummy input

Key features

Supports multiple data types (strings, numbers, dates, etc.)
Cross-platform compatibility
Simple, intuitive API
Generates realistic-looking values
Easy integration via Flutter pub
No external dependencies

Suitable for

Developers creating mockups
Testers needing randomized inputs
Teams building prototype apps
Frontend developers prototyping UIs
Anyone needing quick fake data

Considerations

Not suitable for production data generation
Randomness may not be cryptographically secure
Limited customization options for specific formats
Does not support complex data structures out of the box
Best used in development/testing environments only

Features

API provides generation of:

Integers in any range of numbers
Strings with various characters and length
Colors represented with needed color space
Dates between different moments in time
Names such as John or Mary
UUIDv4 and Timestamp-first UUIDs
URLs with many fragments
IPv4 and IPv6
Locations as either random points or in specified radius

Usage

A simple usage example:

import 'package:mock_data/mock_data.dart';

main() {

  mockName();           // Generate male or female first name. 
  mockName('male');     // Generate male first name. 
  mockName('female');   // Generate female first name. 

  mockInteger(1, 6);    // Generate integer in range from 1 do 6.

  mockString(16);       // Generate string of length 16.
  
  mockIPv4();           // Generate IPv4 represented with 
                        // format(default is '*.*.*.*') as String. 
  
  mockIPv6();           // Generate IPv6, same usage as with IPv4.

  mockColor('hex');     // Generate color represented in hex format.
  mockColor('rgb');     // Generate color represented in RGB format.
  
  mockUUID();           // Generate UUIDv4
  
  mockLocation();       // Generate random location.
  mockLocation(53.55, 108.14, 1000); // Generate random location in 1000 m radius from the specified coordinates.
  
}

These are some basic examples. There are many more methods and they all support tweeking of parameters to suit you in generating random data. By reading examples you can learn more about functionality and usage of mock_data
