Compatibility Policy

As an open-source project, all activities happened when the maintainers have spare time and energy. The support range is limited due to the above condition. Therefore, we have a general compatibility policy to help people that are not actively adapting SDK updates or intended to use any old SDKs to acknowledge the support range.

Policy Details

For all packages, the oldest Dart SDK we typically support is one that was released less than 2 years ago.

Exceptions

• The minimum SDK version will follow the dependencies' requirement. For example: http2: ^2.1.0 requires Dart SDK >=3.0.0.
• The implementation can no longer compatible between the latest and previous SDKs.
• Previous SDKs have security issues that require to use a new version.

To raise your suggestions and reports, use the issue tracker or contact [email protected] if you want to do this privately.
