I'm currently trying to study using flutter riverpod but i get a problem when i'm trying to put flutter_riverpod package i get this error
Because riverpod depends on flutter_riverpod ^0.9.1 which depends on riverpod ^0.8.0, riverpod ^0.8.0 is required.
So, because riverpod is 1.0.0+1, version solving failed.
Running "flutter pub get" in riverpod...
pub get failed (1; So, because riverpod is 1.0.0+1, version solving failed.)
What can i do to fix this problem? I tried to add riverpod package but it's also not working
I think you should open your pubspec.yaml
at first line. probably your name is riverpod
My issue as well like you. name was flutter_riverpod
Check if your project name is riverpod
For me, that was the issue...
Just use a different name for your project.
See this decision tree created by the developer of riverpod for which version to install.
You only want to install one riverpod dependency.
In short, if you are using flutter_hooks (which I would personally recommend), install hooks_riverpod. If you are not using hooks, install flutter_riverpod.
If you are writing pure dart code (no Flutter), then install riverpod.
To reiterate, your pubspec.yaml should only ever include one riverpod dependency.
If you still have version solving issues with your dependencies after this then try deleting your pubspec.lock and reinstall your dependencies.

I have cloned a Repo of a Flutter project from my developer who has the App working perfectly on his machine, and opened the project in VS Code. I did flutter clean, then flutter pub get, and am getting an error as shown below. AFAIK when I clone the repo, I should get his exact files, so I don't understand how I am getting this error, but he does not? Does anyone know how to fix this? TIA for any and all help.
Because every version of charts_flutter from git depends on logging ^1.0.2 and signalr_client >=0.1.3 depends on logging ^0.11.3+2, charts_flutter from git is incompatible with signalr_client >=0.1.3.
So, because app1 depends on both signalr_client ^0.1.6 and charts_flutter from git, version solving failed.
Running "flutter pub get" in App1...
pub get failed (1; So, because app1 depends on both signalr_client ^0.1.6 and charts_flutter from git, version solving failed.)
The reason is simple
The both two packages depends on one common package
Signalr_client & Charts Flutter packages needs the logging package as a dependency.
See the pubspec file
https://github.com/soernt/signalr_client/blob/master/pubspec.yaml
https://github.com/google/charts/blob/master/charts_flutter/pubspec.yaml
But the versions are different for that.
Solution:
Try to remove the logger package from the pub_cache folder.
remote any one package signalr_client or charts_flutter.
use syncfusion_charts instead of charts_flutter
Try to update the flutter packages
I want to add avtar in my App but not able to do this because of dependency conflict/ required version error. I also trying to override dependency but its still not working. also trying this commands.
Flutter clean
Flutter pub get
But still not working.
ERROR:-
Because no versions of random_avatar match >0.0.7 <0.1.0 and random_avatar 0.0.7 depends on flutter_svg ^1.0.3, random_avatar ^0.0.7 requires flutter_svg ^1.0.3.
And because flutter_html >=2.0.0-nullsafety.1 <3.0.0-alpha.1 depends on flutter_svg >=0.22.0 <1.0.0, random_avatar ^0.0.7 is incompatible with flutter_html >=2.0.0-nullsafety.1 <3.0.0-alpha.1.
So, because seedwill_demo depends on both flutter_html ^2.2.1 and random_avatar ^0.0.7, version solving failed.
pub get failed (1; So, because seedwill_demo depends on both flutter_html ^2.2.1 and random_avatar ^0.0.7, version solving failed.)
I guess You working on Flutter 2, but Flutter 3 is released. On pub, some libraries are default compatible with Flutter 3. In this case, not always newest library is the best option. You must find which library is incompatible. Can You put pubspec.yaml to this post? We need TWO version of pubspec.yaml. Previous (which have no error with pub get) and new, with this new library. If You show them, I try find the best version of library for You.
I had problems that look alike, and somehow managed to eliminate them by upgrading flutter parts (updating or reinstalling). Have you tried following commands?
flutter clean
flutter upgrade
flutter pub upgrade
I have been using flutter pub get for updating pubspect.yaml
Now I have found that there is a similar command dart pub get
What are the differences between these two commands?
Using the command flutter pub get you are getting dart packages for Flutter.
Using dart pub get you are getting Dart packages.
You can create dart projects without Flutter and there you’ll need use the command dart pub get.
Every Flutter project is a Dart project
but not every Dart project is a Flutter project, because Flutter is a UI kit or framework for building UIs in the Dart programming language.
When dart pub get gets new dependencies, it writes a lockfile to ensure that future gets will use the same versions of those dependencies. Application packages should check in the lockfile to source control; this ensures the application will use the exact same versions of all dependencies for all developers and when deployed to production. Library packages should not check in the lockfile, though, since they’re expected to work with a range of dependency versions.
If a lockfile already exists, dart pub get uses the versions of dependencies locked in it if possible. If a dependency isn’t locked, pub gets the latest version of that dependency that satisfies all the version constraints. This is the primary difference between dart pub get and dart pub upgrade, which always tries to get the latest versions of all dependencies.
When running flutter pub get (Packages get in IntelliJ or Android Studio) for the first time after adding a package, Flutter saves the concrete package version found in the pubspec.lock lockfile. This ensures that you get the same version again if you, or another developer on your team, run flutter pub get.
Hello I tried to upgrade in_app_purchase 0.3.4+8 package, so that created some bugs due to somes changes. So I downgrade to return to a fonctionnal version but now it's not working... I only downgrade but it's like a modification in cache or other. How can I fix it ?
I try remove pubspeck.lock and flutter pub cache repair but no change
Thank tou
i have a problem to run my flutter app, it seems flutter doesn't recognize it. i tried to connect to internet while running the project but the problem remains the same, here is the error message:
and here is the code where i inserted the dependency :
dependencies:
redux: ^4.0.0
flutter_redux: ^0.6.0
Your package name is likely also redux according to this Github issue. You'll have to change your package name to something other than redux and you should be able to flutter pub get.
this error was caused by the fact that i named my app REDUX, i changed it and it works now.
