Install and Publish Active eCommerce Flutter App on Android and iOS (Codecanyon App)

Install and Publish Active eCommerce Flutter App on Android and iOS (Codecanyon App)
---
I have purchased the Active eCommerce CMS and the Flutter App from CodeCanyon, and the CMS is already installed on my server.

I need an experienced Flutter developer to do the following:

Install and configure the Flutter App for both Android and iOS

Set up the app with my branding, logo, colors, API path, purchase code, and system key

Build and send the APK and AAB files for Android, and the TestFlight or iOS build

Provide me with a working version that I can test

Payment will be released only after I confirm the app is working on both platforms.

Bonus if you can also:

Configure social login (Google and Facebook)

Enable push notifications (Firebase)

Upload the app to the Play Store and App Store (optional)

I will provide:

Full Flutter source code

CMS admin access

Activation key and purchase code

My total budget for this project is $89. This will be a fixed-price, milestone-based payment after successful completion.
