How to run flutter projects with different/older Dart SDK dependencies?
I had a similar problem:
My pubspec.yaml had the following:
environment: sdk: ">=2.1.0 <3.0.0"However when running flutter packages get I got the following error:
Running "flutter packages get" in xxx-app-mobile...The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.Because xxx_app requires SDK version >=2.1.0 <3.0.0, version solving failed.pub get failed (1)I tried using the exact version name as the environment variable it did not work. I tried:
flutter upgradeflutter cleanflutter update-packagesReceived the same error when running flutter packages get I then downgraded the version requirements in the pubspec.yaml to:
environment: sdk: ">=2.0.0 <3.0.0"And flutter packages get worked...
First open your command (cmd) as an adminstrator then upgrade flutter : flutter upgrade it will do everything for you
