What problem does it solve? Bringing agent-generated UI to Flutter mobile apps requires manually wiring message intake, surface rendering, and version translation, with no guarantee the mobile output matches what web or MCP-UI hosts render. This Skill generates the Flutter A2UI host layer and verifies it against the same document the web host renders. ## Core Features & Use Cases - Flutter A2UI host scaffolding: Emits a surface controller, surface widget, and v1.0-to-v0.9 translation layer under lib/a2ui/ using the genui renderer and a2ui_core message types. - Parity verification: Runs a parity test asserting the Flutter surface produces the same observable output (heading, body text, labelled buttons) as the web and MCP-UI hosts before reporting success. - Use Case: You are building a mobile app whose screens are driven by agent output over AG-UI or MCP-UI. Run the scaffolder against your Flutter project to get a verified rendering host that stays consistent with your web surfaces. ## Quick Start Ask the agent to scaffold an A2UI rendering host into your Flutter project and run the parity test to confirm it matches the web host output.
