Requires SDK version >=2.16.0 <3.0.0, version solving failed

Question

The current Dart SDK version is 2.14.4.

Because trackkit requires SDK version >=2.16.0 <3.0.0, version solving failed. pub finished with exit code 1

My pubspec.yaml :

    environment:
  sdk: ">=2.16.0 <3.0.0"

after running flutter master:

Flutter is already up to date on channel master
Flutter 2.13.0-0.0.pre.145 • channel master • https://github.com/flutter/flutter.git
Framework • revision de4eb16254 (3 hours ago) • 2022-03-18 06:00:24 -0400
Engine • revision edf31ab695
Tools • Dart 2.17.0 (build 2.17.0-220.0.dev) • DevTools 2.11.4

It shows that my Dart is upgraded to 2.17.0 ? I am still unable to run!

Answer 1

1. You need to upgrade your Dart SDK with:

   flutter upgrade
   

2. make sure to edit your environment in pubspec.yaml :

   environment:
     sdk: ">=2.16.0 <3.0.0"
