I'm certainly the first to ask this question because I found just nothing on the internet about this issue. When I try to import mongodart in the main file of my flutter application, I got this error in my IDE (VsCode) and also when I try to run the project with flutter run:
The name 'State' is defined in the libraries 'framework.dart' and 'mongo_dart.dart'.
more:
Compiler message: lib/main.dart:37:32: Error: Expected 0 type arguments. class _MyHomePageState extends State { ^ lib/main.dart:34:20: Error: The return type of the method 'MyHomePage::createState' is

subtype of #lib2::State<#lib2::StatefulWidget>. _MyHomePageState createState() => new _MyHomePageState(); ^ file:///home/quentin/flutter/packages/flutter/lib/src/widgets/framework.dart:1: Error: This is the overridden method ('createState'). lib/main.dart:41:5: Error: Method not found: 'setState'. setState(() { ^^^^^^^^ lib/main.dart:41:5: Error: The method 'setState' isn't defined for the class '#lib1::_MyHomePageState'.

Try correcting the name to the name of an existing getter, or defining a getter or field named 'widget'. title: new Text(widget.title),
Note: The StatefulWidget is the one from the sample app.
I'm sure this problem is caused by mongodart because when I remove:
import 'package:mongo_dart/mongo_dart.dart';
any form of error disappear. Here's the code that causes the problem.
