Flutter App Rebrand & Deploy

I already run the Academia LMS platform on my own server through a custom course-selling CMS, and I have the official Flutter mobile source code supplied by the vendor. The code builds and runs, but before I can publish it on Google Play I need a few quick branding changes and a production build.

Here is what I want from you:

• Point the app to my server by replacing the default base API/website URL in the Flutter source.
• Swap in my logo as the app icon and splash asset, and update the visible application name accordingly (no other colour-scheme tweaks are required).
• Produce a signed release build (AAB preferred) that passes Play Console checks, plus the keystore and any build notes so I can replicate the process later.

That is the entire scope—no new features or UI redesigns. If you have recent experience white-labelling Flutter apps and pushing them to Google Play, this should be straightforward. I will provide the complete source, my logo files, the new app name, and access to the Play Console once the build is ready for upload.
