Sorry but I´m relatively new at Flutter/Dart and I have literally no idea what's happening, can you show me the code so I can help you and change whatever is failing in the library?

mitchhymel commented 6 years ago

I had this same problem. It's because each FloatingActionButton by default has a HeroTag, so if you have multiple FABs on screen at the same time, there is an error of duplicate HeroTag. A fix would be to either: 1) Generate within the library (behind the scenes from the user) and assign unique hero tags for each FAB used 2) Require a hero tag for each FAB

Change 2 is simple. See this commit on my fork of this repo. Sorry I fixed this for my scenario a while back but never got around to submitting a PR.

Leondev7 commented 6 years ago

I'm trying to fix this, but I never had this problem. Can you tell me how to reproduce it?

Update fab_menu_item.dart to this to add the hero tag of the index:
