Hello! I want to use these nice charts, but I have some issues. Please, can you help me?

here my pubspec.yaml:

name: charts_flutter
version: 0.6.0
description: Material Design charting library for flutter.
author: Charts Team <charts_flutter@google.com>
homepage: https://github.com/google/charts

environment:
  sdk: '>=1.23.0 <3.0.0'

dependencies:
  # Pointing this to a local path allows for pointing to the latest code
  # in Github for open source development.
  #
  # The pub version of charts_flutter will point to the pub version of charts_common.
  # The latest pub version is commented out and shown below as an example.
  # charts_common: 0.6.0
  charts_common:
    path: ../charts_common/
  collection: ^1.14.5
  flutter:
    sdk: flutter
  intl: ^0.15.2
  logging: any
  meta: ^1.1.1

dev_dependencies:
  mockito:
  flutter_test:
    sdk: flutter
  test: ^1.3.0

I proyect are in the path:

DHJW-iMac-2011:charts admin$ pwd
/Volumes/6TB/production-VARIOS/Github/id0000150_flutter_dart_example/id0000150_9/charts

Also I did flutter packages get

DHJW-iMac-2011:charts_flutter admin$ pwd
/Volumes/6TB/production-VARIOS/Github/id0000150_flutter_dart_example/id0000150_9/charts/charts_flutter
DHJW-iMac-2011:charts_flutter admin$ flutter packages get
Running "flutter packages get" in charts_flutter...              
The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.

Because charts_flutter depends on charts_common from the path which requires SDK version >=2.1.0 <3.0.0, version solving failed.

pub get failed (1)
DHJW-iMac-2011:charts_flutter admin$

Please any help will be appreciate. Thanks so much!

Yes, I'm also having this issue. Quite confused.

switch to dev channel until a new stable is out (hopefully soon)

flutter channel dev
flutter doctor
ascmp commented 5 years ago

To state the obvious, the issue is that Flutter 1.0.0 (channel stable) uses Dart 2.1.0 (build 2.1.0-dev.9.4 f9ebf21297), where 2.1.0-dev version is considered to be strictly smaller than 2.1.0, while "charts_flutter depends on charts_common [...] requires SDK version >=2.1.0".

kieron-mcintyre commented 5 years ago

@ascmp I see, by 'strictly smaller' you mean a lower version. So this package currently can't be used with Flutter's stable release.

As @zoechi suggests, I've been able to change to the Flutter beta channel (which is presumably more stable than dev) and I can use the charts package now. Thanks for your help!

Should be solved by now using stable channel.

thanhgiangleo commented 5 years ago

upgrade Dart & Flutter version, the problem will be solved.

I got the same error message after download the newer version. And solved it by deleting my previous flutter and dart on my environment path and assign a new flutter path to it.
