The current Dart SDK version is 2.10.5.
Because path_provider 2.0.1 requires SDK version >=2.12.0-259.9.beta <3.0.0 and no versions of path_provider match >2.0.1 <3.0.0, path_provider ^2.0.1 is forbidden.
So, because harmonoid depends on path_provider ^2.0.1, version solving failed.

My Dart SDK version is 2.12.0, and the Flutter version is 2.0.1. I created a new project and copied all your dependencies. The project worked without any problems.
For saving your time, I recommend upgrading to the stable channel and Flutter 2 using these commands or this link.
flutter channel stable
flutter upgrade
If you don't want to migrate your Flutter and Dard SDK versions yet,
I would recommend you to try and remove the version from the line:
path_provider: ^2.0.1
so it would look like this: path_provider:
run: pub get again
run your project again
Eventually I would recomment to migrate to the newest version of the SDKs and upgrade all your dependencies. This is just a temporary solution.

I've been getting an error ever since I tried adding integration_test package along with get_test and it's primarily due to the fact that just_audio depends on crypto: ^3.0.0 while integration_test depends on crypto: ^2.1.5.
I tried to look online to see if it's possible to only install dependencies without dev_dependencies however it seems like flutter pub cli tool doesn't support that yet based on this issue.
Here is my pubspec.yaml
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^1.0.2
share: ^2.0.1
get:
get_storage:
shared_preferences: ^2.0.5
audio_service: 0.17.0-nullsafety.0
just_audio: ^0.7.4
dev_dependencies:
flutter_test:
sdk: flutter
get_test: ^3.13.3
integration_test: ^1.0.2+1
test: ^1.14.4
This is the error I am getting.
Because every version of integration_test depends on flutter_driver any from sdk which depends on crypto 2.1.5, every version of integration_test requires crypto 2.1.5.
And because just_audio 0.7.4 depends on crypto ^3.0.0 and no versions of just_audio match >0.7.4 <0.8.0, integration_test is incompatible with just_audio ^0.7.4.
So, because egy_fm_radio depends on both just_audio ^0.7.4 and integration_test ^1.0.2+1, version solving failed.
pub get failed (1; So, because egy_fm_radio depends on both just_audio ^0.7.4 and integration_test ^1.0.2+1, version solving failed.)
I think this specific issue could have been be resolved by updating the Flutter SDK to the latest (>=2.2.0), but if there's anybody experiencing a similar issue, consider using Dependency overrides to override dependencies of built-in packages such as integration_test and flutter_driver.
dependency_overrides:
crypto: ^3.0.0
Note that this involves some risk and pub will show you a warning during dependency resolution.
Looking through your pubspec.yaml it appears the problem lies within the crypto dependency mismatch.
Inside your pubspec.yaml you can explictly declare the latest crypto version:
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^1.0.2
share: ^2.0.1
crypto: 3.0.1
get:
get_storage:
shared_preferences: ^2.0.5
audio_service: 0.17.0-nullsafety.0
just_audio: ^0.7.4
dev_dependencies:
flutter_test:
sdk: flutter
get_test: ^3.13.3
integration_test: ^1.0.2+1
test: ^1.14.4
What happens is that when you use so many packages, some of those packages use some other packages. It may so happen that two or more packages use the same package.So, it creates an error incase of mismatch because you cannot have two different versions of the same package.
The project was working like a charm that started issues after the upgrade to flutter 2.0. following are errors upon pub get.
[delivered] flutter pub get
Running "flutter pub get" in delivering...
Because every version of flutter_localizations from sdk depends on intl 0.17.0 and firebase_auth_web >=0.3.0-dev.1 <0.4.0-1.0.nullsafety.0 depends on intl ^0.16.1, flutter_localizations from sdk is incompatible with firebase_auth_web >=0.3.0-dev.1 <0.4.0-1.0.nullsafety.0.
Because firebase_auth >=0.18.4 <=0.18.4 depends on firebase_auth_web ^0.3.2+2 and firebase_auth ^0.18.4+1 depends on firebase_auth_web ^0.3.2+3, firebase_auth ^0.18.4 requires firebase_auth_web ^0.3.2+2.
Thus, flutter_localizations from SDK are incompatible with firebase_auth ^0.18.4.
So, because iDelivered depends on both flutter_localizations any from SDK and firebase_auth ^0.18.4, version solving failed.
pub get failed (1; So, because delivered depends on both flutter_localizations any from SDK and firebase_auth ^0.18.4, version solving failed.)

My suggestion is for a few week don't update your flutter version
To downgrade your flutter (Master channel):
flutter downgrade 1.22.6
Since you upgraded to Flutter 2.0, the flutter sdk is the source of the flutter_localizations. So, you have to upgrade your firebase dependencies e.g. firebase_auth, firebase_core to at least version 1.0.0.
My advice is that if the packages you are using have not been upgraded to null-safety OR they have not been recently updated, you should just stick to the 1.22.6 stable version of flutter for now.
You can try to add dependency_overrides to resolve this conflicts :
dependency_overrides:
intl: "<0.17.0"
Downgrade flutter using flutter downgrade version
my solution for this issue..
download both 2.0.2 flutter SDK and 1.22.6 flutter SDK. change flutter SDK project-wise.
In my app,
I upgrade following three pubs to latest
firebase_analytics: ^7.1.1,
firebase_core: ^1.0.1,
firebase_messaging: ^9.0.0
I downgrade google mobile ads SDK to 7.6.9 in IOS pod file, it works for me. https://github.com/FirebaseExtended/flutterfire/issues/4931
I have imported a project in android studio flutter. But, there is an incredible amount of version conflict coming in. If one solves other rises and if that goes down, other one rises. I am trying to get all packages and it is showing me the following error as below.

And there are 4-5 dependency version error. How can I solve this version error thing in one click or I can just somehow skip this version problem and get the thing done. Please help, Thanks in Advance.
Whenever conflicts between dependencies occur, the simplest solution is to just remove the version number of both that dependencies and type 'any' without quotes in front of them.
for example let's say this following two dependency conflicts:
shared_preferences: ^0.5.7+3
requests: ^3.3.0
then do following:
shared_preferences: any
requests: any
After this do pub get and issue will be resolved. Now, most importantly, don't leave any dependency on this form. instead goto pubspec.lock file and search these two dependencies. Flutter itself chooses the versions that don't conflict, copy those and replace it to pubsec.yaml
You can use dependency_overrides in your pubspec.yaml to force a specific package version. The package version will override any reference to a dependency in the entire app.
In your case you could use
dependencies:
flutter:
sdk: flutter
...
cupertino_icons: ^1.0.0
dependency_overrides:
intl: ^0.17.0-nullsafety.2
See dependency_overrides for more information.
Replace intl: 0.17.0-nullsafety.2 version with intl: 0.16.1 and remove intl from dependency overrides.
Now, run pub get command.
You can simply change the version of package that is causing conflic with another version which is compatible with your dart SDK. I tried it and the problem was solved.
had the same problem; ran the following command:
flutter pub upgrade --major-versions
if you don't mind having the latest version of all the dependencies while solving version conflict issues, this should be a quick fix.
I had this problem after resetting my Mac mini.
If you still have the pubspec.lock file at the last successful run (or get it from another dev, on that dev's computer the project is still running).
flutter clean.
Replace pubspec.lock by the old one.
Run the project again.
Flutter_test depends on meta 1.1.8 and firebase_login depends on meta ^1.2.2.

I have same problem with bloc:
Because every version of passcode_navigator from git depends on flutter_bloc ^7.3.3 and every version of feature_menu from path depends on flutter_bloc ^8.0.0, passcode_navigator from git is incompatible with feature_menu from path
I resolve it with adding to pubspec:
dependency_overrides:
flutter_bloc: any
Do this,
meta: ^1.1.8
And then, run this,
flutter pub get
hi there try to downgrade the version of meta to 1.1.8 i tried and it worked with me in flutter 1.20.1
I experienced a similar issue with Firebase auth and permission_handler:
# pubspec.yaml:
dependencies:
flutter:
sdk: flutter
firebase_auth: ^1.4.1
permission_handler: ^5.1.0+2
The error message (truncated):
Because permission_handler ^5.1.0 depends on permission_handler_platform_interface ^2.0.2 which depends on plugin_platform_interface ^1.0.2, permission_handler ^5.1.0 requires plugin_platform_interface ^1.0.2.
And because firebase_auth 1.4.1 depends on firebase_core_platform_interface ^4.0.1 and no versions of firebase_auth match >1.4.1 <2.0.0, permission_handler ^5.1.0 is incompatible with firebase_auth ^1.4.1.
So, because my_flutter_project depends on both firebase_auth ^1.4.1 and permission_handler ^5.1.0+2, version solving failed.
A solution that worked for me:
Update permission_handler to the latest version:
flutter pub add permission_handler
Update meta to 1.2.2
meta: ^1.2.2
also update flutter using flutter upgrade command
flutter upgrade
I am trying to install image_picker and firbase_storage in my flutter project. But whatever version I try to install, it fails. and gives error like this -
Because image_picker >=0.3.0 requires Flutter SDK version >=0.1.4 <2.0.0 and image_picker <0.3.0 requires SDK version >=1.8.0 <2.0.0, image_picker is forbidden.
I have tried out installing every version but not able to install even a single version.
Flutter doctor -v is working fine and following is the content of my pubspec.yaml file

One way to approach this kind of dependency issues is that just let the pub to fetch the appropriate version if you are facing any issues or conflicts with dependency.
Add the dependency on pubspec.yaml as below
dependencies:
image_picker: any
or
dependencies:
image_picker:
Then check the pubspec.lock file and find the version number.
In this case, you may get
image_picker:
dependency: "direct main"
description:
name: image_picker
url: "https://pub.dartlang.org"
source: hosted
version: "0.5.0"
Then you can modify pubspec.yaml as
dependencies:
image_picker: ^0.5.0
You need to allow a newer image_picker version.
Try
dependencies:
image_picker:
or
dependencies:
image_picker: ^0.5.0
