Project description:
"JOB POST: Need Real-Time Always-On Order Alert System for 6amMart (Laravel + Flutter)

Budget: ₹6,000 – ₹12,000
Location Preference: India/Nepal/Bangladesh
Deadline: 5–10 days
Project Type: One-time custom integration
Script Used: 6amTech – 6amMart (Codecanyon)
Apps: Vendor App + Delivery App (Flutter)

Project Requirement

I am using the 6amMart code (6amTech multi-vendor delivery script) and I need an advanced real-time order alert system for the Vendor App and Delivery App.

Current FCM notifications in 6amMart are delayed, unreliable, and get blocked by Xiaomi/Oppo/Vivo devices.

I want a Zomato/Swiggy-style instant alert that works even when the app is minimized, locked, or removed from recent apps.

This must show a full-screen alert popup with order details instantly.

✔ What You Need to Build (For 6amMart Codebase)
1. Real-Time MQTT or WebSocket System

Integrate with 6amMart Laravel backend

Instant delivery of NEW ORDER event

Under 300ms latency

No dependency on FCM

Auto reconnect

Scalable for 500–5,000 online stores/drivers

2. Flutter Foreground Service (6amMart Vendor + Delivery App)

Runs permanently in background

Works on Xiaomi / Oppo / Vivo

Not killed by battery optimization

Real-time listener for new order events

Auto restart after device reboot

Auto reconnect after network change

3. Full-Screen Alert Popup (Flutter)

Must include:

Order ID

Items

Address

Amount

Accept/Reject buttons (Delivery App)

OK/Close button (Vendor App)

Alert sound + vibration

Must wake the phone screen

4. Laravel Backend Integration (6amMart Admin/Store Logic)

Trigger event on NEW ORDER for vendor

Trigger event on DELIVERY ASSIGNMENT

ONLY these alerts (I do NOT want order preparing/processing alerts)

Secure with API key / jwt

Use 6amMart order APIs and existing order logic

5. Android Background Restrictions Handling

Auto-start permissions

Doze mode handling

Foreground notification service

Boot receiver

OEM battery restriction bypass logic

✔ Deliverables (Specific to 6amMart)
Vendor App (6amMart Flutter Code)
