update dart sdk for flutter

I would like to use dart SDK >= 2.2.0 with flutter. But my current version used BY Flutter is 2.1.2

flutter --version
Flutter 1.2.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 8661d8aecd (2 months ago) • 2019-02-14 19:19:53 -0800
Engine • revision 3757390fa4
Tools • Dart 2.1.2 (build 2.1.2-dev.0.0 0a7dcf17eb)

I tried to install the 2.2.0 version independently and I succeed :

dart --version
Dart VM version: 2.2.0 (Tue Feb 26 15:04:32 2019 +0100) on "macos_x64"

However, Flutter doesn't use this version as you can see above. I tried to replace files of the dart-sdk used by flutter (flutter/bin/cache/dart-sdk) by the version that I installed independently, but when I try to run Flutter after that I have a snapshot problem so I have put back the original dart-sdk folder in the flutter directory.

Do you have any ideas how can I update it?

PS: I downloaded flutter very recently (10 days ago) from here: https://flutter.dev/docs/get-started/install/macos

It might be due to the fact you are on channel stable which is the most secure builds of the four channels to get updated (channels are listed here)

If you are a bit more curious to try out the new features without having to risk bad builds I advocate channel beta:

Every month, we pick the "best" dev build of the previous month or so, and promote it to beta. These builds have been tested with our codelabs.

where the stable channel has this description:

When we believe we have a particularly good build, we promote it to the stable channel. We intend to do this more or less every quarter, but this may vary. We recommend that you use this channel for all production app releases. We may ship hotfixes to the stable channel for high-priority bugs, although our intent is to do this rarely.

You can change the channel to point at beta by running this command in your terminal: flutter channel beta followed by flutter upgrade to ensure you have got the last release for this particular branch.

Let me know how this affect your situation.

  • It totally helped. Now my flutter dart version is 2.3.0! Thank you :)
  • It's also worth mentioning that Flutter includes the Dart SDK and not to install them separately.
  • thanks for sharing, searching for this issue for a long time.
  • But can we actually update the Dart SDK version and keep the current Flutter version? I have a situation where this has become a necessity.
  • @cVergel, just to clarify; you want to run with a never release of the Dart SDK without upgrading the Flutter version? This trick will allow you to utilize a newer Dart SDK. You must upgrade your Dart version, however.
