When more than 3 Bottomnavigationbar items are provided the type, if unspecified, changes to Bottomnavigationbartype.shifting
When we have more than 3 items in Bottomnavigationbar, if unspecified, it changes the type to Bottomnavigationbartype.shifting.
When the Bottomnavigationbar’s type is Bottomnavigationbartype.shifting the items text and icons are rendered in white...
When the Bottomnavigationbar guy is shifting text items and icons are rendered blank...
To solve this problem, just set the type to Fixed.
new BottomNavigationBar(
type: BottomNavigationBarType.fixed,
items: [...],
);
post more informs about your type question, snippets of code, error messages, etc...
