This error occur whenever i click the Google Sign-In button. enter image description here. After entering the google sign-in button, it should navigate the user to a bottom navigation bar enter image description here. If the user haven’t sign out, the app will save the token and the user will access the bottom navigation bar directly without required google sign in again…How can i solve it?
Exception has occurred.
FlutterError (There are multiple heroes that share the same tag within a subtree.
Within each subtree for which heroes are to be animated (i.e. a PageRoute subtree), each Hero must have a unique non-null tag.
In this case, multiple heroes had the following tag: <default FloatingActionButton tag>
# Here is the subtree for one of the offending heroes: Hero)

Hero widget heroTag must be a unique tag. if you duplicate it, will throw this error.
If you have more than one
FloatingActionButtonin your code, set theirheroTagattributes to different values(String).
