Flutter lower dart version

Question

I'm getting the following error due to Dart version of my flutter setup when I run the flutter get packages command:

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

Because project depends on intl_translation >=0.14.0+1 <0.17.0 which requires SDK version >=1.12.0 <2.0.0, version solving failed. pub get failed (1) exit code 1

My framework version:

Flutter 0.6.0 • channel beta • https://github.com/flutter/flutter.git
Framework • revision 9299c02cf7 (2 weeks ago) • 2018-08-16 00:35:12 +0200
Engine • revision e3687f70c7
Tools • Dart 2.1.0-dev.0.0.flutter-be6309690f

I would like to learn if there's some kind of command to lower dart-sdk version of the flutter framework, thanks in advance.

Solution 1

In the Flutter install directory execute

git checkout v"0.5.0" // for example

You can check which versions are available in the Flutter GitHub repository https://github.com/flutter/flutter

Solution 2

You can only change the Dart version if you change to a Flutter version that contains the desired Dart version.

Change the dependency to

dev_dependencies:
  intl_translations: ^0.17.0

besides changing the dependency, how is it possible to change flutter version?

[Canberk Ozcelik]

can you be more specific on what it really does?

[Günter Zöchbauer]

You can checkout a specific branch using flutter channel or a specific tag using git checkout [branch, tag or commit hash]. Then run flutter doctor

[Canberk Ozcelik]

so the dart sdk is basically bundled within flutter sdk there's no way to configure versions separately

[Günter Zöchbauer]

Exactly, there is no way.

[Canberk Ozcelik]

so basically, I have changed the dependency to intl_translation: 0.17.0 and it's working with the latest flutter/dart-sdk version

[Günter Zöchbauer]

Sounds great. .
