    • Apple Xcode (on Mac)

    • Ensures that we’ve agreed to all software development licenses.

    • Checks for connected devices.

    • Verifies that Flutter can recognize any connected hardware devices.

    • Recommends any changes required to get them connected and working.

    • Outputs a diagnosis, listing out issues found and recommendations.

  2. If you want to run in local Chrome, make sure web security is disabled to avoid CORS errors.
