Fake class

A comprehensive, full-featured fake data generator utility (Fake) designed for unit testing, widget testing, mock models, UI placeholders, network simulation, and in-memory/disk temporary image and file creation.

Usage Example:

import 'package:flutter_prakash_core/fp_core.dart';

// 1. Mock User Data & Profiles
final name = Fake.fullName;
final email = Fake.email;
final avatar = Fake.avatarUrl();
final bio = Fake.paragraph;
final socials = Fake.socialLink('github');

// 2. Mock Media & Files
final placeholderUrl = Fake.imageUrl(width: 600, height: 400);
final memoryBytes = await Fake.imageMemory(color: Colors.red);
final transparentBytes = Fake.transparentImageMemory();
final tempFile = await Fake.imageFile(filename: 'profile.png');

// 3. Mock Collections & Lists
final mockUsers = Fake.list((i) => {
  'id': Fake.id,
  'name': Fake.fullName,
  'email': Fake.email,
  'price': Fake.price(min: 10, max: 99),
}, count: 5);
