Same issue - when I add a snackbar to my web app and click its action, mouse input is consistently disabled entirely. Do we know why the issue reproduces in the Flutter Gallery but not in the official Snackbar example? I'd love to find a way to work around this. |
|
Any solution for this issue? |
|
I haven't been able to narrow down exactly what the problem is, but one thing I have noticed is that 99% of the times I get this error, I also have a layout problem (overflow, or whatever). |

I've managed to reproduce this with a small code sample. However, it is a bit tricky... using the following code as a starting point, run in a macOS desktop app. Observe that you can scroll up and down, click, drag, etc. Then wrap the last Note that as part of this last bit of clicking/scrolling, your console will probably also fill with a bunch of "hit test" errors, but it will eventually get "Unhandled Exception: 'package:flutter/src/rendering/mouse_tracker.dart': Failed assertion: line 201 pos 12: '!_debugDuringDeviceUpdate': is not true" Note that you can usually reproduce by starting the app fresh including the Flutter doctor for me: |

Facing the same issue. Using MouseRegion on two text widgets in the container, and hover_card package on that container |

Can confirm, just replicated the same issue while debugging on a windows machine, except there was a single screen with both a FAB and a bottomAppBar. Have not tried yet to create the FAB or bottomAppBar after initial screen build. |

hello, any update on this? |
and others
I always get the following exception when I click the action text on the snackbar, and after that, the Flutter app and mouse becomes unresponsive.
