Hi there, I recently purchased a VPN source code from CodeCanyon and I’m looking for an experienced Flutter developer to help me get it market-ready. Important: This isn't just a visual reskin. The project requires deep knowledge of V2Ray/Xray-Core. If you haven't worked with VLESS Reality or XTLS-Vision protocols before, this project will likely be too difficult. Here is what I need help with: Core Upgrade (The Heavy Lifting): The current code is using older libraries. I need you to update the native dependencies (like flutter_v2ray or libxray) to the latest versions. The goal is to make sure the app connects successfully to VLESS Reality configs using flow=xtls-rprx-vision. Remote Configuration: Right now, servers are hardcoded. I need you to swap this out so the app fetches server nodes via a JSON API (I’ll provide the link). It needs to cache the list for offline access and have a pull-to-refresh feature. UI/UX Refresh: I have the assets ready (icons, colors, splash). I need a full rebrand and a simplified layout—removing the complex "developer logs" so it's clean for the end user. Final Build: Change the package name to my brand, sign the app, and provide the .aab file, the APK, and—most importantly—the Keystore file (.jks) with credentials so I can update it later. To wrap things up: To approve the project, I’ll just need to see a screen recording of the app connecting to a test string I provide. Once I verify the APK works on my side, we are good to go!
