Other channels |
We currently have one other channel, master. |
People who contribute to Flutter use this channel.This channel is not as thoroughly tested as |
the beta and stable channels.We do not recommend using this channel as |
it is more likely to contain serious regressions.The latest documentation for the master branch |
is at: https://main-api.flutter.dev<topic_end> |
<topic_start> |
Changing channels |
To view your current channel, use the following command:To change to another channel, use flutter channel <channel-name>. |
Once you’ve changed your channel, use flutter upgrade |
to download the latest Flutter SDK and dependent packages for that channel. |
For example:info Note |
If you need a specific version of the Flutter SDK, |
you can download it from the Flutter SDK archive.<topic_end> |
<topic_start> |
Upgrading packages |
If you’ve modified your pubspec.yaml file, or you want to update |
only the packages that your app depends upon |
(instead of both the packages and Flutter itself), |
then use one of the flutter pub commands.To update to the latest compatible versions of |
all the dependencies listed in the pubspec.yaml file, |
use the upgrade command:To update to the latest possible version of |
all the dependencies listed in the pubspec.yaml file, |
use the upgrade --major-versions command:This also automatically update the constraints |
in the pubspec.yaml file.To identify out-of-date package dependencies and get advice |
on how to update them, use the outdated command. For details, see |
the Dart pub outdated documentation. |

join the groups Flutter announce and Dart announce.When facing Dart errors after upgrading Flutter, |
consider using the dart fix command |
to automatically migrate your code. |
Not every breaking change is supported in this way, |
but many are.To avoid being broken by future versions of Flutter, |
consider submitting your tests to our test registry.The following guides are available. They are sorted by |
