Plugin that provides a bidirectional scrollview
License: BSD 3-Clause "New" or "Revised" License
This package for Flutter allows you to scroll in both horizontal and vertical directions.
It works as follows:
new BidirectionalScrollViewPlugin(child: <replace with your own widget>)Please file issues and feature requests.
it doesn't allow setState, if I replaced BidirectionalScrollViewPlugin with SingleChildScrollView setState works fine but the other way round doesn't work
Running flutter packages pub upgrade failed with the following output:
ERR: The current Dart SDK version is 2.2.1-dev.0.0.flutter-7c70ab1817.
Because bidirectional_scroll_view requires SDK version >=1.19.0 <2.1.0, version solving failed.
Can you help me fix this please?
I'd like to see scroll bars to give the user an idea where they are.
These would be optional, for both x and y axis.

You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
To generate an app bundle, run:
flutter build appbundle --target-platform android-arm,android-arm64,android-x64

Hi,
I was looking for something you did! Thanks!
I tested it without a problem but now, in my case, i'm trying to display something which needs to be related to the screen size and I can't figuring out how I can make it..
Can you make a simple example for passing argument in the build() ?
In the initState, we can't have the screen size because it's not already build :/
Thanks for your help and for your good work!
Regards
Is it possible to use listview builder inside bidirectional view, if yes can you please share how...
import 'package:bidirectional_scroll_view/bidirectional_scroll_view.dart';
import 'package:flutter/material.dart';
void main() {
runApp(new MyApp());
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
BidirectionalScrollViewPlugin _plugin;
@override
void initState() {
super.initState();
_plugin = new BidirectionalScrollViewPlugin(
child: _buildWidgets(),
velocityFactor: 2.0,
);
//_plugin.offset = new Offset(10.0, 10.0); // use this method to set a new offset where appropriate
}
@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
appBar: new AppBar(
title: new Text('Bidirectional ScrollView Plugin'),
),
body: new Center(
child: Row(
children: [
Expanded(
flex: 1,
child: Container(
color: Colors.red,
width: 100,
height: 100,
),
),
Expanded(
flex: 1,
child: _plugin,
)
],
)),
),
);
}
Widget _buildWidgets() {
List<Widget> list = new List();
for (int i = 0; i < 1024; i++) {
list.add(new Container(
padding: new EdgeInsets.all(5.0),
color: Colors.white,
height: 80.0,
width: 120.0,
child: new Container(
color: Colors.grey,
child: Text("$i"),
),
));
}
return new Row(
children: [
new Column(
children: list.map((widget) {
return widget;
}).toList(),
),
],
);
}
}
I've just copy paste the tutorial given from https://pub.dev/packages/bidirectional_scroll_view
Got this instead when trying to run it.
======== Exception caught by rendering library =====================================================
The following assertion was thrown during performResize():
Vertical viewport was given unbounded height.
Viewports expand in the scrolling direction to fill their container. In this case, a vertical viewport was given an unlimited amount of vertical space in which to expand. This situation typically happens when a scrollable widget is nested inside another scrollable widget.
If this widget is always nested in a scrollable widget there is no need to use a viewport because there will always be enough vertical space for the children. In this case, consider using a Column instead. Otherwise, consider using the "shrinkWrap" property (or a ShrinkWrappingViewport) to size the height of the viewport to the sum of the heights of its children.
bidirectional_scroll_view: ^0.1.1
Failure when archive ios release:
Runner/GeneratedPluginRegistrant.m:10:9: Module 'bidirectional_scroll_view' not found
#if __has_include(<bidirectional_scroll_view/BidirectionalScrollViewPlugin.h>) #import <bidirectional_scroll_view/BidirectionalScrollViewPlugin.h> #else @import bidirectional_scroll_view; #endif
I'am having this issue when archive to ios release. It's some module is not working and I've found same error when release apk on android.
Normally, the root of the GitHub repo contains the package contents (lib, test, example, etc).
It's not a big deal, but we suggest that you move flutter-bidirectional_scrollview_plugin/bidirectional_scroll_view/* up into flutter-bidirectional_scrollview_plugin
Thanks!
Stack(

Should be

I would like to request the implementation of 2 separate controllers to use to match the scrolled quantity of lateral scrollviews that I would like to implement.
I'd like to be able to zoom in and out using the pinch gesture.
This should be optional, and I should be able to specify a range for the zoom.
Hi, thanks for a nice library.
it is really easy to use and makes my code very clean and short.
however I find it quite laggy during acroll for both side for records around 1000 and columns around 20, this symptom does not exist in listview.
Any suggestion please?
Please can you remove from Manifest.
When you build gradle from android this now is an error.
Non-nullable instance field '_state' must be initialized.
I try to keep your code here, and then just make relevant adjustments for NullSafety, maybe you can refer to it.
Adjustment of bidirectional_scroll_view.dart
Adjustment of main.dart
If you need it, I can also provide PullRequest.
Please upgrade flutter SDK version.
The current Dart SDK version is 2.1.0-dev.1.0.flutter-ccb16f7282.
Because bidirectional_scroll_view 0.0.5 requires SDK version <2.0.0 and no versions of bidirectional_scroll_view match >0.0.5 <0.1.0, bidirectional_scroll_view ^0.0.5 is forbidden.
So, because MyProject1 depends on bidirectional_scroll_view ^0.0.5, version solving failed.
