I get this error with my function, "The argument type 'Object?' can't be assigned to the parameter type 'String?'." on the lines containing snapshot.docs[0].data(''),
Please help me fix it, any help would be greatly appreciated!
Future getNewsPostDetails(String newsPostId) async {
QuerySnapshot snapshot = await FirebaseFirestore.instance.collection('newsPosts').where('newsPostId', isEqualTo: newsPostId).get();
newsPostDetails blogPostDetails = newsPostDetails(
newsPostTitle: snapshot.docs[0].data('newsPostTitle'),
newsPostAuthor: snapshot.docs[0].data('newsPostAuthor'),
newsPostContent: snapshot.docs[0].data('newsPostContent') ,
date: snapshot.docs[0].data('date'),
);
return blogPostDetails;
}
CodePudding user response:
If you make sure that snapshot.docs[0].data('newsPostTitle')
is a String
, you can convert it to String
like:
snapshot.docs[0].data('newsPostTitle') as String?
