Random data generator code to populate database

        lifecycleScope.launch {
            for(day in arrayOf("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")){
                for(i in 0..10){

                    val images = arrayOf(R.drawable.test_image1, R.drawable.test_image2, R.drawable.test_image3)

                    val base64Image = ImageBase64Converter.encode(ContextCompat.getDrawable(applicationContext, images.random())!!,false)

                    AppDatabase.get(applicationContext).dao().addItem(ItemData(
                        name= arrayOf("Family Meal", "Ranchit", "Beef Bomb", "Chicken Fajita", "Urban X").random(),
                        description = "description text test",
                        restaurant = arrayOf("Big Meal", "EatMore", "Grilled", "Chief Ahmed", "Fast & Food").random(),
                        image = base64Image,
                        originalPrice = DecimalFormat("#.#").format(Random.nextDouble(80.0, 150.0)).toDouble(),
                        discountPrice = DecimalFormat("#.#").format(Random.nextDouble(50.0, 120.0)).toDouble(),
                        day = day.uppercase()
                    ))

                }
