I have an existing Flutter code-base that already compiles for Android; the only missing piece is a working connection to a Phantom Solana wallet. All UI elements are in place, so your focus is strictly on wiring the wallet flow: deep-link or in-app browser hand-off, secure key handling, signature requests, and returning the public key back to Dart. You will work on my Git repo, add the necessary Solana web3 / wallet-adapter packages, and push a clean, tested commit. I need this done within a few hours, so please start your bid with “I can do it” to confirm you can meet the turnaround. Acceptance criteria: • On a real Android device, tapping “Connect Wallet” launches Phantom, allows approval, and returns to the app with the user’s address. • Subsequent taps recognise an already-connected wallet and pull the current balance via web3. • Code is organised, commented, and builds with flutter build apk without extra steps. If you are comfortable with Flutter, Dart, Phantom SDK, deep linking and Solana RPC endpoints, this should be a quick win. Let’s get it shipped today.
