Every Flutter release: open Xcode, archive, Transporter, drag IPA, submit. Then Play Console, upload AAB, fill notes. Repeat forever. DeployKit replaces that with one terminal command. Store credentials once, drop STORE_DEPLOYMENT.md in your repo, tell your agent "ship 1.2.0 to both stores." It builds, uploads, reports back. No Xcode. No CI/CD. No fastlane config hell. Just a markdown file your agent reads. MIT. Free on GitHub. From the makers of Nucleus MCP.
