当我运行 flutter run 时，我得到:

Running "flutter packages get" in townsquare...                  
The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.

Because flutter_circular_chart 0.0.3 requires SDK version >=1.19.0 <2.0.0 and no versions of flutter_circular_chart match >0.0.3 <0.1.0, flutter_circular_chart ^0.0.3 is forbidden.
So, because mobile depends on flutter_circular_chart ^0.0.3, version solving failed.

pub get failed (1)

这是我的 pubspec.yaml

name: mobile
description: A new Flutter project.

version: 1.0.0+1

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  carousel: ^0.0.1
  http: "^0.11.3+16"
  validate: "^1.6.0"
  url_launcher: "^3.0.2"
  shared_preferences: "^0.4.2"
  font_awesome_flutter: "^7.0.0"
  flutter_circular_chart: "^0.0.3"
  flutter_local_notifications: ^0.3.6

dev_dependencies:
  flutter_test:
    sdk: flutter

  assets:
   - images/flutter.jpg
   - images/logo.png
   - images/bg_viewer.jpg

以上所述，请赐教我，怎么了?

With the above, please enlighten me, what's wrong?

推荐答案

那是因为您使用的是: Dart版本2.1.0-dev.0.0.flutter-be6309690f 和名为 flutter_circular_chart 具有约束

That's is because you are using : Dart version 2.1.0-dev.0.0.flutter-be6309690f and the plugin named flutter_circular_chart has a constraint

https://github.com/xqwzts/flutter_circular_chart/blob/master/pubspec.yaml

environment:
   sdk: '>=1.19.0 <2.0.0'

您可以派生项目并更新sdk约束，并引用到您的存储库:

You can fork the project and update the sdk constraint and ref to your repository:

赞:

flutter_circular_chart:
    git: https://github.com/your_repo/flutter_circular_chart.git

注意如果您在他们的仓库中打开一个问题来通知开发人员您所遇到的问题，也可以.

Note Also would be fine if you open an issue in their repo to notify the devs about the issue that you have.
