Open your terminal and use the following command to determine your Dart version: dart --version. Copy your dart version and go to pubspec.yaml file and change your sdk version >=2.19.6 <3.0.0 to your current dart version. You have to replace version that is on left side 2.19.6.

here is my problem

`Resolving dependencies... The current Dart SDK version is 3.2.3.

Because al_quran_app requires SDK version >=3.10.6 <4.0.0, version solving failed.`

  1. first check your dart version in your terminal by text : dart --version enter image description here

  2. go to pubspec.yaml and change your env sdk to your current sdk before

after

  1. run flutter clean, and then run flutter pub get

I have had the same issue. Go to pubspec.yaml and change then make it :

environment:
  sdk: '>=2.15.1 <3.0.0'

No need to upgrade flutter if you are already in the latest version. Just do this and I hope this will work.

Go pubspec.yaml and edit minimun to your dart version

From environment: sdk: ">=2.15.1 <3.0.0"

To environment: sdk: ">=2.12.0 <3.0.0"

When prompting your command just use flutter pub add ... instead of dart

flutter channel <master or beta>
flutter upgrade

But if you check dart --version is the version that matches the version the project requires and still get the error "version solving failed." like this.

enter image description here

flutter clean
flutter channel <master or beta>
flutter upgrade --force

you can resolve this error by changing : flutter_lints: ^2.0.0 To flutter_lints: ^1.0.0 in pubspace.yaml.

to
