Flutter, access icon size in BottomNavigationBarItem

I have a list containing BottomNavigationBarItems.

final List<BottomNavigationBarItem> = [...BottomNavigationBarItems...]

Now I want to access the icon size from one of the BottomNavigationBarItems.

final iconSize = items[index].icon.size;

But then I get the error that the getter "size" isn't avaible for the type "Widget".

How can I solve that problem?

BottomNavigationBarItem Class

Solution

  • The parameter icon of BottomNavigationBarItem has the type Widget. You have to cast it first as Icon like this:

    final iconSize = (items[index].icon as Icon).size;
