Automate interactive Flutter tests with marionette_mcp | Mateusz Wojtczak

Why watch

This video introduces Marionette MCP, an open-source tool that gives AI coding agents the ability to interactively test Flutter apps at runtime. Emma from the Flutter team discusses with Mateusz Wojtczak from LeanCode how this tool enables AI agents to tap around running apps, capture screenshots, compare UI against Figma designs, review Flutter logs, and automatically fix visual discrepancies before code review. Developers working with AI-assisted development workflows and Flutter testing will learn practical integration techniques.
