A walkthrough of an AI-assisted Flutter app development workflow using Google's Stitch (AI design agent) and Antigravity (agentic IDE). Stitch generates UI designs from text prompts, which are then exported via MCP connectors to Antigravity, where an AI agent writes the full Flutter/Dart codebase following Clean Architecture with Riverpod. The demo builds a Daily Habit Tracker app from prompt to running emulator in about 10-12 minutes. Includes setup steps, example prompts, best practices, and limitations of the agentic approach.
