[syncfusion_flutter_calendar] is zoom in/out possible ?

[Jiayang-21]

Use case

Now the Sync Fusion calendar 's day/week view , it can display about half day of event where users sometimes want to see more. Google/Apple allow users to pinch to zoom in and out and adjust. It looks like sync fusion does not support this kind of behavior, or am I missing something?

Proposal

enabling pinch to zoom in/out

Hi Jiayang,

The SfCalendar widget provides the TimeSlotViewSettings.timeIntervalHeight property, which allows you to control and adjust the height of each time slot in the Day and Week views. However, pinch‑to‑zoom support is not available in the calendar, and this is the current behavior.

We have already logged a feature request for the calendar zooming support in our feedback portal. Feature requests are prioritized based on overall demand and importance, so this enhancement may be included in one of our upcoming releases. We will notify you once it is implemented, and you can track its progress using the link below.

In the meantime, we have prepared a custom sample where pinch gestures are captured using a GestureDetector, and the gesture’s scale value is used to dynamically update the timeIntervalHeight. This approach enables zoom‑in and zoom‑out functionality in the SfCalendar.

We have shared the sample for your reference, and you can customize it further based on your specific requirements.

Mugunthan.
