List of random data to generate:

• colors with various color spaces
• date between different moments in time
• integers in between range of numbers
• IPs ~ IPv4 and IPv6
• name; male or female first name
• strings of different length and characters
• url with different parts; routes, GET query parameters and fragments

Usage #

A simple usage example:

import 'package:mock_data/mock_data.dart';

main() {
  
  // Mock string of given length and group of characters:
  
  // Generate string of length 16(default) and any 
  // combination of letters and digits.
  mockString();
  
  // Generate string of length 10 and any combination
  // of letters and digits.
  mockString(10);
  
  // Generate string of length 15 and any combination
  // of lowercase letters and digits.
  mockString(15, 'a#');
  
  // Generate string of length 3 and any combination
  // of letters and digits.
  mockString(3, '!');
  
  // Generate string of length 7 and any combination
  // of letters.
  mockString(7, 'aA');

  // Mock integer in range from min to max, inclusive:
  
  // Generate integer in range from min(default 1)
  // to max(default 10). Works with negative numbers.
  mockInteger();
  
  // Generate integer in range from 3 to 30.
  mockInteger(3, 30);
  
  // Generate integer in range from -15 to 5.
  mockInteger(-15, 5);
  
  // Generate integer in range from -25 to -15.
  mockInteger(-25, -15);

  // Mock IPv4 or IPv6 with given format:
  
  // Generate IPv4 represented with
  // format(default is '*.*.*.*') as String. 
  mockIPv4();
  
  // Generate IPv4 starting with groups of
  // 192, 168 and 0, followed by any integer
  // of last group.
  mockIPv4('192.168.0.*');
  
  // Generate IPv4 starting with groups of
  // 192 and 168, followed by any integer
  // of last two groups.
  mockIPv4('192.168.*.*');
  
  // Generate IPv4 starting with groups of
  // 192, followed by any integer
  // of next two groups and end group of 55.
  mockIPv4('192.*.*.55');

  // Generate IPv6, same usage as with IPv4.
  mockIPv6();
  mockIPv6('*:e331:93bf:*:a7c9:a63:*:*');
  mockIPv6('e1b3:7bae:*:3474:*:c0cc:462:c4b9');

  // Mock first name from passed gender:
  
  // Generate male or female first name. 
  mockName();
  
  // Generate male first name. 
  mockName('male');
  
  // Generate female first name. 
  mockName('female');
  
  // Mock color from a given color model:
  
  // Generate color represented in hex or rgb format.
  mockColor(); 
  
  // Generate color represented in hex format.
  mockColor('hex');
  
  // Generate color represented in RGB format.
  mockColor('rgb');
  
  // Generate color represented in HSL format.
  mockColor('hsl');
  
  // Generate color represented in HSV format.
  mockColor('hsv');
  
  // Generate color represented in CMYK format.
  mockColor('cmyk');
  
  // Mock url from passed parameters:
  
  // Generate url starting with http scheme.
  mockUrl('http');
  
  // Generate url starting with http or https
  // followed by 1 to 4 paths.
  mockUrl('*', true);
  
  // Generate url starting with https
  // followed by 1 to 4 paths
  // followed by fragment(permalink).
  mockUrl('https', true, false, true);
  
  // Mock DateTime from two moments in time:
    
  // Generate DateTime object in between
  // 1970-01-01 01:00:00.000 and now.
  mockDate();
  
  // Generate DateTime object in between
  // 1995-00-00 00:00:00.000 and now.
  mockDate(DateTime(1995));
  
  // Generate DateTime object in between
  // 1995-00-00 00:00:00.000 and now.
  mockDate(DateTime(1995, 26, 7), DateTime(2005, 26, 7));
  
  // Generate DateTime object in between
  // 2015-10-21 04:29:00.000 and now.
  mockDate(DateTime.parse("2015-10-21 04:29:00"));
  
  // Generate range of mocks of particular
  // function(more at documentation).
  mockRange(mockString, 3);
  mockRange(mockInteger, 5, min: 3, max: 15);
  mockRange(mockIPv4, 7, format: '*.*.0.0');
  mockRange(mockName, 5, gender: 'male');
  mockRange(mockColor, 12, returnModel: 'hex');
  mockRange(mockUrl, 4, scheme: 'http', withQuery: true);
  mockRange(mockDate, 5, firstMoment: DateTime(2010, DateTime.november, 2));
