You can do
@override
void initState() {
super.initState();
query = widget.blog_id; // or whatever way you want to use it
}
you cannot do
String query = widget.blog_id;
since widget is assigned after State is created.

You can use it as widget.blog_id.

But not during construction, because the state's widget field is not assigned until afterwards. Use initState() as advised in Gazihan Alankus' answer. – realh Feb 28 '22 at 16:45
