We just added support for two **runtimes**:

- **Functions**: Dart 3.12
- **Sites**: Flutter 3.44

Pick **Dart 3.12** in the runtime dropdown when creating or updating a Function, or pick **Flutter 3.44** under your Site’s **Runtime settings**. The change applies to the next deployment, your active deployment is not affected until you redeploy.
