Error: The argument type 'String' can't be assigned to the parameter type 'DiagnosticsNode'. - 'DiagnosticsNode' is from #31962
Description
After upgrading to 1.5.9-pre.108 I seem to be getting this issue with 3 packages I use, should I take this up with the packages or is it something that you guys will fix?
Pacakges affected in my project:
multi_image_picker: ^4.2.0
flutter_sticky_header: ^0.3.4
cached_network_image: ^0.7.0
Steps to Reproduce
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter_sticky_header/flutter_sticky_header.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: Page1(),
);
}
}
class Page1 extends StatelessWidget {
final String title;
const Page1({Key key, this.title = "Page 1"}) : super(key: key);
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(title),
),
body: CustomScrollView(
slivers: <Widget>[
SliverStickyHeader(
header: Text('Users'),
sliver: SliverList(
delegate: SliverChildBuilderDelegate(
(context, i) => Text(i.toString()),
),
),
),
],
));
}
}
Added pubspec dependency
flutter_sticky_header: ^0.3.4

This might be related to Dart 2.3.0 version bump, here you can find a temporary workaround for
cached_network_image(should also work for the other 2 packages): Baseflow/flutter_cached_network_image#171 (comment)calvinmuller commentedon May 2, 2019
it feels sooo wrong - but for now it will have to do, given i've been building against master its way to difficult to go back now!
Thanks!
vijayawoshe commentedon May 2, 2019
For me 4 to 5 Plugins are failing
1.sentry
2. flutter_advanced_networkimage
3.cached_network_image_provider
4. fllushbar
5. flutter_svg etc
with the same errors.
This issue has to be solved asap.
Thanks
thanhhuan1990 commentedon May 2, 2019
I have gotting the same errors with 2 libs with same issue.
This issue should be solved asap.
Thanks

The root cause is #30983. The change to
contextthere is breaking. I think it should probably be reverted and relanded in a more gradual migration instead of an in-place breaking change? This also breaksfirebase_crashlytics, which passescontextover theMethodChanneldirectly under the asusmption that it's a String.flutter/pluginsCI is currently red based on this./cc @jacob314 @kroikie
mklim commentedon May 3, 2019
My mistake, the breaking change was intentional. https://groups.google.com/forum/#!topic/flutter-announce/hp1RNIgej38 #27327
This is unfortunately a difficult breaking change for plugins authors to deal with, since plugins users could be using
stable(in which this is a String) ormaster, in which this is aDiagnosticsNode. Just migrating to the latest version will break users on older versions of Flutter.I think plugins authors can work around this without breaking either new or old versions of Flutter for now by type checking and handling the property differently depending on what it is. That's not an ideal fix though.
jacob314 commentedon May 3, 2019
We can change the type of context from
DiagnosticsNodeto Object for a few months to allow for a gradual migration.Based on analysis of all pub packages this change should break about 13 packages. I am happy to help anyone who needs to migrate their package to migrate it.

flutter_svg has been fixed. Let me know if you are still having issues with it.

Guys I am completely stuck after upgrading to the 1.7.8+hotfix.3 I have been unable to compile in iOS. I have tried downgrading back to 1.5 but the error is still there. I have tried creating a new project and just once it managed to compile to the simulator. After that its been giving me nightmares. Please please. When is this issue going to be resolved. We are dealing with tight timelines for my clients projects. I am now at an advanced stage of the project. Please I need a resolution to this. This is severe.
samfrank commentedon Jul 29, 2019
My fix for this was to update the flutter_svg to
0.13.0CarrieUp commentedon Aug 3, 2019
Same issue for Flutter 1.7.8+hotfix.4
even I upgrade flutter_image to ^2.0.0 and flutter_image_compress to ^0.4.0

@CarrieUp have you tried updating your dependency on
flutter_image_compress? It looks like it's up to version0.6.3, and you're using0.4.0.CarrieUp commentedon Aug 4, 2019
@tvolkert thank you so much, I solve the problem by your suggestion: upgrading dependency on flutter_image_compress version to 0.6.3
kawynsean commentedon Aug 10, 2019
Running into the same issue as well. Looks like I just need to update my dependencies. New to this so thanks for any help!
