Flutter SliverAnimatedList with firestore data updated

Question

My scenario: a team of 5 users are using the app and looking at the same stream of data. When one user updates the data, the other team members should be informed via a simple animation.

Using SliverAnimatedList I am able to animate when new data is added or existing data being delete using animationKey.currentState.insertItem or animationKey.currentState.removeItem.

However, when the data value is updated (temperature change from 55C to 60C) I cannot find a way to initiate the animation.

Been banging my head on this for a few day, any pointers and directions are welcome.

`AnimatedSwitcher` ? or `TweenAnimationBuilder`? – pskink Jun 02 '20 at 17:11 — pskink, Jun 02 '20 at 17:11

In the end, I deletee then added the record to animate the change. Looks pretty good once you get the animation right and coordinate between the delete and add.
