New version of this doesn't work with Streambuilder , but Listview and Gridview work

[AlexMoon90]

I have been using staggered_grid_view well for months.
Yesterday I found the problem that staggered_grid_view doesn't render as the stream changes in Streambuilder. but listview and griedview work well with same way.
Please, check this issue. I really need staggered_grid_view. thanks.

if you build this coding, you would find Listview change counter but Staggered_grid_View don't work.

import 'package:flutter/material.dart';
import 'package:rxdart/rxdart.dart';
import 'dart:async';
import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
// This widget is the root of your application.
@OverRide
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}

class MyHomePage extends StatelessWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
var bloc = Block();

@OverRide
Widget build(BuildContext context) {

return Scaffold(
  appBar: AppBar(
    title: Text(title),
  ),
  body: Center(
    child: Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        Text( 'You have pushed the button this many times:',  ),
        Center(
          child: Container(
            child: StreamBuilder(
              stream : bloc.observe,
              initialData: 0,
              builder: (context, snapshot) {
                return

                 Column(

                             return
                             Text("Listview : ${snapshot.data.toString()}");
                           }),
                     ),

                      ),
                      )

                   ],
                 );

              } ),

  ])),
  floatingActionButton: FloatingActionButton(

    tooltip: 'Increment',

);

}
}

class Block {

var controlloer = StreamController();

I'm also having this issue, currently having to use an older version of this package.

[letsar]

Hi, can you tell me in which version of this package this work, and in which it doesn't?

[letsar]

I've found where it comes from. It's available on master (not yet on pub). Let me know if everything is OK for you. Then I will create a new version and publish it.

[JordanADavies]

Yeah, that fixes it. Thanks a lot!
