Do you have the error message of the test that failed? It feels weird that the even loop is holding and accessing the api of FlutterTextField even if the FlutterTextPlatformNode has been destroyed |
Yea, if you look at the linked issue I have all the debugging information there. |

@chunhtai no problem, do you think this represents a problem that in practical use of flutter on macos that should be hotfixed? |

The crash happens because there is a dangling pointer when the FlutterTextPlatformNode is deleted but the main event loop has a retain on the FlutterTextField. I'm not sure how problematic this is in practice but it affected tests.
