[Feature Request] Scroll to programatically

[johanlantz]

Thanks for a really cool widget!

I am trying to figure out a way to scroll to a _position programmatically but I have not managed to solve it.

For the scenario I had in mind I would need a way to programmatically move to specific offsets of the DiagonalScrollView when certain things happen but I am not sure how to accomplish that.

All suggestions are welcome :-)

Hi!

Currently there is no internal way to do it programmatically.

I will take advantage of some time in my Coronavirus quarantine to create a basic controller that allows this scenario.

Thank you for the suggestion!

That sounds great. I have a pet project I would like to try (also during the Corona quarantine) and your plugin looks really promising for what I am thinking about.

Thanks for accepting the idea.

Hi!
I've published a new version, could you try it out?

[johanlantz]

Cool,

I have tried but I can't get it to move. I have just stored the controller from the onCreated callback and then I try to use moveBy when pressing a button but it does not move. Perhaps I am using it wrong?

The sample code based on your example is here:

Hi!

I've tried your example and now it's working fine. Turns out I was using a counterintuitive approach by moving the origin using negative values.

Can you try it again?

Thanks!

Amazing, was going to ask for animation support but saw you already implemented that.

It looks great. If I have time to start my side project I might have more ideas but for now this looks really nice.

Thanks for sharing and have a nice weekend (even if in quarantine :-), we are a bit restless here in Barcelona as well)
