I am getting an error:
       type 'Future<dynamic>' is not a subtype of type 
       'StreamTransformer<List<dynamic>, List<dynamic>>" in my BLOC.

    
This is the structure of my app:
     A BLOC (namely, reports_bloc.com).
     A Repository (namely, repository.dart).
     A API Provider (namely, api_provider.dart).

Hello Devs,

I keep in receiving this error message "I/flutter (11828): Another exception was thrown: setState() called in constructor: CartState#040e6(lifecycle state: created, no widget, not mounted)
". I believe this is due to how I'm using setState() method in my CartState class below:

class CartScreen extends StatefulWidget{

  createState(){
    return CartState();
  }

import 'package:flutter/material.dart';

import 'dart:async';

void main() => runApp(new BackButtonOverrideDemoWidget());

class BackButtonOverrideDemoWidget extends StatefulWidget{
  @override
  _BackButtonOverrideDemoWidgetState createState() => new _BackButtonOverrideDemoWidgetState();
}
