I am currently trying to implement localization in my Flutter App but whenever I try to add the dependency for flutter_localization, I get the following error Message:
Because the timer depends on flutter_localization from SDK which doesn't exist (could not find package flutter_localization in the Flutter SDK), version solving failed.
I have also correctly added the path to both my flutter and dart SDKs in Android Studio.
Here is my pubspec.yaml file:
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
version: 1.0.0+1
environment:
sdk: '>=2.18.2 <3.0.0'
dependencies:
flutter:
sdk: flutter
intl: ^0.17.0-nullsafety.2
cupertino_icons: ^1.0.2
sqflite: any
shared_preferences: ^2.0.15
path_provider: any
flutter_localization:
sdk: flutter
flutter_cupertino_localizations: ^1.0.1
dev_dependencies:
flutter_test:
sdk: flutter
flutter_lints: ^2.0.0
flutter:
uses-material-design: true
I can't access GlobalMaterialLocalizations without flutter_localization and apparently, this is the easiest solution. I have already tried many solutions like checking version compatibilities and updating all dependencies. can you guys help me out?
Thanks in Advance!
Upgrading SDKs, Upgrading Dependencies, reinstalling flutter and Dart, and more
You misspelled the package
Replace
flutter_localization:
sdk: flutter
With
flutter_localizations:
sdk: flutter
Take note on the s on flutter_localizations

I am getting an error like this:
Because every version of flutter from sdk depends on collection 1.16.0 and syncfusion_flutter_datagrid >=19.1.54-beta <20.1.48 depends on collection >=1.9.0 <=1.15.0, flutter from sdk is incompatible with syncfusion_flutter_datagrid >=19.1.54-beta <20.1.48.
So, because datagrid_json_datasource depends on both flutter from sdk and syncfusion_flutter_datagrid ^19.1.65-beta, version solving failed.
pubspec.yaml:

syncfusion_flutter_datagrid: ^19.1.65-beta
flutter:

i try too chenge sdk version when i change to sdk version and also try flutter clean and flutter pub get.
Try updating to newer version of syncfusion_flutter_datagrid.
Add to pubspec.yaml:
dependencies:
syncfusion_flutter_datagrid: ^20.3.52
Then run flutter pub get
I tested this with multiple Flutter versions and the one you should use is the 2.2.0 because this is the version which contains the Collector 1.9.0, you cannot use another version of Collector or override it because dart:Collector contains different data structures that are used in the code base of flutter.
This is the pubspec.yaml that works for me for Flutter 2.2.0
Hope it helps you :)

I am relatively new to Flutter, and don't seem to be able to figure this out.
Here is my pubspec.yaml:
name: app
version: 1.0.0+1
environment:
sdk: ">=2.16.0-80.1.beta <3.0.0"

dev_dependencies:
flutter_test:
sdk: flutter
flutter_lints: ^1.0.0
build_runner: ^2.1.7
flutter:

I did of course try to run $(flutter) pub get, update flutter channel to the latest master and dev, run $flutter packages pub run build_runner watch, but to no avail...
The dev channel in particular lists "Dart 2.16.0 (build 2.16.0-134.1.beta)" as a dependency tool, but I still get the same compile error.
Just got back to this project, with a fresh mind, and I quickly fixed the issue by changing the environment sdk to ">=2.15.1 <3.0.0".
Okay so i have built an app nearly a year and half ago for my company, my boss recently wanted me to add a new screen to it and i did using all old and deprecated code of firebase and everything else (i really really dont wanna update them because i know everything nearly changed and building a whole new app would be better than editing this lol, so i'm trying to avoid that option), the app runs on Android just fine, but it doesnt build on ios and it does not allow me do "flutter build ios" in the terminal giving above error when trying to build ios or trying to pub Get.
Granted my intl version was ^0.16.1 , then it would say that it requires 0.17.0 , then I changed it based on another post here to intl: ^0.17.0-nullsafety.2 but it gives the output above. what's the problem?

You need to upgrade your flutter version on your local machine to flutter 2.0+ now cause you are importing null safety supported dependency which uses dart sdk 2.12.0 but you have 2.7.0 which is making conflict with the other dependencies. If you do have 2.0+ already then upgrade the sdk of your app from pubspec.yaml. You will then have to update your code to full sound null safety starting from upgrading all the dependencies then the code, its not that hard even if your app is using firebase I get my apps upgraded to null safety within a week. Once all gets sorts out you'll have no trouble with your project in importing some null safety dependency or some else more importantly you will be able to have better performance of your app and can keep all the dependencies to support latest versions and might possible you app will be android 12 ready too
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.
I'm trying to install rxdart by copying it from https://pub.dev/packages/rxdart/versions/0.7.1#-installing-tab- , but its showing some error.
The current Dart SDK version is 2.3.0-dev.0.5.flutter-a1668566e5.
Because flutter_course depends on rxdart >=0.1.0+1 <0.16.0 which requires SDK version >1.12.0 <2.0.0, version solving failed.
pub get failed (1)
exit code 1
I tried using flutter upgrade.
But that doesn't change anything.
