While trying to work with STOMP, websockets, facing issue for "packages get" after updating pubspec with required stomp/websocket details. I have tried for stomp, stompdart, websocket none of them worked.
Error observed while running "packages get" is
"The current Dart SDK version is 2.1.0-dev.4.0.flutter-4eb879133a.
Because project_name depends on stompdart >=0.0.2 which requires SDK version >=1.5.0 <2.0.0, version solving failed.
pub upgrade failed (1)"
If I try to downgrade flutter version then it has thrown exception informing 'current project needs SDK version > 2.0.0
Please help to clear the issue or suggest some other way as I am using STOMP at server end.
had the same issue, it can be solved in two ways:
solved it by adding this to my yaml file :
dependency_overrides:
stomp: ^0.7.3
dependencies:
stomp: ^0.7.3
flutter:
sdk: flutter
using the dependency_overrides works.
Secondly by running "pub upgrade" in your project directory
https://github.com/rikulo/stomp/issues/18#issuecomment-435748215
Well, this is not a definitive answer, but it may help you.
I forked a chinese library that seems to work named JStomp and did some translations. Let me know if it work since I am also interested to be able to work with STOMP on Flutter.
Here's my fork: https://github.com/raedcran/flutter_jstomp

So i am trying to get started with riverpod and creating a new flutter project with the "click and counter" default sample.
As soon as I add on the pubspec
flutter_hooks: ^0.18.0
hooks_riverpod: ^2.0.0
And
import 'package:hooks_riverpod/hooks_riverpod.dart';
I get this error on the debug console and can't figure it out what is the problem
: Error: Method not found: 'Error.throwWithStackTrace'.
../…/framework/provider_base.dart:904
Error.throwWithStackTrace(error, chain);
^^^^^^^^^^^^^^^^^^^
: Error: A non-null value must be returned since the return type 'Never' doesn't allow null.
../…/framework/provider_base.dart:898
Never _rethrowProviderError(Object error, StackTrace stackTrace) {
^
Error.throwWithStackTrace was added in Dart 2.16 (Flutter version 2.10 from Feb 8, 2022).
https://api.flutter.dev/flutter/dart-core/Error/throwWithStackTrace.html
(Check the #Since annotation.)
If your Flutter/Dart version is below that, you'll get the error you saw.
Two options that may help are:
Specify an exact version of dependencies (don't use ^ ahead of version)
upgrade Flutter/Dart to at least 2.10/2.16
flutter upgrade
If your problematic package (hooks_riverpod: ^2.0.0 in your case) is listed with ^, it'll use the latest version that doesn't break dependencies.
I'm guessing that when you created a new project and used that same dependency version, upon initial pub get it downloaded a newer version of the package (or a newer version of a dependency that that package uses) into "pub cache" which is relying on the new Error API method.
Your project will store this information in:
<your_project_dir>/dart_tool/package_config.json
The min Dart SDK version listed for the package should normally have changed from 2.12 to 2.16. (update: it's been updated now) This would give us a hint that we need to update our Flutter/Dart if we see our build failing.
In an earlier version of this answer, I noted that the ^ prefix on package dependency versions is supposed to prevent these types of issues, but I'm no longer certain it was meant to cover this situation where the underlying platform needs to be updated (as opposed to a breaking change in the API of the package itself).
Anyways, at first glance, it might make sense to go from 2.0.0 to 3.0.0 for a package version # when it depends on a new core Dart API method that did not exist when 2.0.0 was published.
Notes
The author of riverpod also wrote the new API for Error.throwWithStackTrace so likely the latest version of hooks_riverpod is using the latest API changes. (The version you're listing 2.0.0 is pre-release currently). You could try earlier versions of riverpod in your pubspec.yaml (such as 1.0.3)
for anyone facing " Method not found: 'Error.throwWithStackTrace' " with firebase.
try to add this to your pubspec.yaml
dependency_overrides:
firebase_messaging_platform_interface: 3.1.6
I saw this.
How about trying flutter pub upgrade?
If it is not resolved, then check analyzer version and check which dependency locks that.
As noted in Baker's answer, Error.throwWithStackTrace was recently added in Dart 2.16.
If you're getting an error about Error.throwWithStackTrace not being found for some package, the package author neglected to update their package's minimum Dart SDK version. You should report that to the package maintainer. In the meantime, you should use an earlier version of the problematic package or use a newer version of the Dart SDK.
Try running flutter upgrade
By this it will upgrade your flutter and dart SDK version and hope it resolves your issue
if you are still facing the issues after "flutter upgrade" or you use this line of code in pubspec.yaml
dependency_overrides:
firebase_messaging_platform_interface: 3.1.6
you receive this type of errors

so Try to upgrade your gradle version, this line in your build.gradle
classpath 'com.android.tools.build:gradle:4.1.0'
after doing that it may be possible it ask you to change your
gradle-wrapper.properties
distributionUrl=https://services.gradle.org/distributions/gradle-6.1.1-all.zip
to
distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip
also upgarde this packages
firebase_core: ^1.10.0
firebase_messaging: ^11.1.0
The plugins advance_pdf_viewer, flutter_webview_plugin use a deprecated version of the Android embedding.
To avoid unexpected runtime failures or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of
Flutter will remove these deprecated APIs."
I follow some documentation but is still not working.
i upgrade and downgrade my version but still not working.
should I share my mainActivity.kt and manifest file?
if there is no newer version of advance_pdf_viewer, flutter_webview_plugin available with the new android V2 embedding, your can't do anything inside of your app. Keep watching for plugin updates of these 2 plugins... or go to it's github project and open an issue to fix it. Sometime the master branch has already fix it. In this case you could try to link direct to the master branch and not to a version in pub.dev
for advance_pdf_viewer i use $flutter pub add advance_pdf_viewer
This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):
dependencies:
advance_pdf_viewer: ^2.0.1
Alternatively, your editor might support or flutter pub get. Check the docs for your editor to learn more.
Import it
Now in your Dart code, you can use:
import 'package:advance_pdf_viewer/advance_pdf_viewer.dart';
and for webview I try dependencies:
flutter_webview_plugin:
git: https://github.com/nuc134r/flutter_webview_plugin.git
and it all works for me than you.
I am building a basic app using flutter, in which I had to use provider, I added Provider dependencies in pubspec.yaml file but getting this error please help, I added the error below not able to fix this problem I have the latest flutter SDK
To solve this use lower version of Provider dependency as newer version of provider depends on newer version of Flutter SDK and your application's Flutter SDK is old one so it will have compatibility issues, So just degrade the version of dependency or you can also run pub outdated command and it will suggest you compatible version as per your SDK.
Using Flutter, I am trying to update my dart dependency 2.6.0 but I get an error
Because *project_name* requires SDK version >=2.6.0 <3.0.0, version solving failed.
pub get failed (1)
exit code 1
I want to use the new features that dart offers, such as Extension Methods. How could I go about upgrading my dependency? I have installed the newest stable version of dart on my computer, but regardless I still get that error.
A couple of things that might help:
From this issue, you can try ensuring that you've updated enviroment in your pubspec.yaml file like so:
environment:
sdk: ">=2.0.0-dev.68.0 <3.0.0"
Another thing that might help is just double checking the steps in this post or on the dart installation page to ensure that you've updated to the latest version correctly.
I'm having this issue when I've added http dependency in my flutter project. Can anyone please help me with it?
If you get the message:
Because every version of flutter_test from sdk depends on...
It means flutter_test depends on a dependency with version lower than you specified in another dependency.
To solve this, open pubspec.yaml, and remove the version number of the problem dependency:
Example:
Change
archive: ^2.0.13 --> remove this number
To:
archive:
You have provided or trying to use http: ^0.12.0 dependency on implementing API calls in pubspec.yaml file but flutter_test will require http: ^0.11.3+17. That's why it fails. Please replace
dependencies:
flutter:
sdk: flutter
http: ^0.12.0
with
dependencies:
flutter:
sdk: flutter
http: ^0.11.3
Hope it will help you out.
In my case, I somehow deleted sdk: flutter:
dependencies:
flutter:
sdk: flutter
I was facing a similar error. I solved it by removing all the version numbers from the dependencies: section in pubspec.yaml.
So, if my pubspec.yaml looked like this before:
dependencies:
freezed_annotation: ^0.14.3
I changed it to this:
dependencies:
freezed_annotation:
I'm assuming this fetches the latest "possible" version of each package.
Can you please provide the dependencies in your pubspec.yaml? It looks like your app depends on at least http 0.12.0 but flutter_test specifically requires http 0.11.3+17 (an older version) which makes it fail.
If your app doesn't have too many dependencies that could broke, you can try to upgrade your Flutter version: flutter upgrade.
It most probably will fix this problem. But always be sure to understand that your app might break at unexpected places.
So you're fine if:
either you're doing it for small app
or it's big app at work and it has extensive tests that will tell you something has broken
if big app without tests, be sure to test every important place of the app, where dependencies are being used
Try to change the dependency version that you were added in your pubspec.yaml file
don't use the current or latest version try some previous versions of dependency.
for ex - if you are using latest sqflite version then chnage to previous version of that and then re-run your whole project.
In my case IDE referred to an an older version of dart because of fvm. Seems like 'run' button called fvm flutter run, but not flutter run as I expected. After I deleted fvm folder from the project the problem has gone.
Change depending attributes version inside pubspec.yaml
if it says depands on http *** than change http version
or if it says depands on collection *** than change collection version.
