"Draw Signature" flow function: canvas does not expand on full screen

Thank you for sharing this option! How do you get into the JS-editing mode of a flow function?

@stayfoolish Drop the flow component onto the logic canvas, then after selecting the Draw Signature function press ‘Enter’ > you will see ‘Edit subflow template’ > select the ‘JS Draw signature’ function then press ‘Enter’ to open the node and view the underlying code.


Setting the code like described above:

const res = await supersonic.api.signature.open({ aspectRatio: 1 });

results on iOS in a behaviour with full screen available for portrait-screen, but not for landscape screen. Also it hides in landscape a part of the signature taken in portrait.

portrait - full screen available for signature:

landscape - only half screen available for signature:

Also setting the value for aspectRatio to “2” or “3” doesn’t improve the landscape mode.

As the landscape mode makes sense for taking a signature, unfortunately this hack is still not solving the problem :no_mouth:.

Hi @Mevi,
today there were several updates to components in Composer. Does it your go-through of components is doing well and the ‘draw signature’ is about to hop on the menu soon :smile: ?

Unfortunately it looks like that’s going to be some time longer :sweat_smile: Almost all the view components have been gone through (it’ll take some versions for the changes to be released) but it seems like there’s additional enabling development required from another team before flow functions can be worked on :cry:

Hi Mevi, is there some progress regarding the fixing of the ‘draw signature’ flow function? The current version is just impractical.

Not as of yet, the enablement of the flow function development was pushed back over the major rewrite of our plugin structure, but it’s under work again as far as I know. And when that is available it’ll still be a while of course, since we have to do the change and have it released in a version of the Preview App first etc.

Hi @Mevi ,
in the “monthly update for May-June” you are mentioning, that Flow function improvements have now been unblocked, and work on them is starting.
Does it mean that the ‘draw signature’ flow function is about to be adjusted now?

Hi @Chris_Revell ,

some time ago you shared a hack to expand the signature pad on full portrait screen. :vertical_traffic_light:

Were you able to figure out, how to capture a signature on the full landscape screen as well? :traffic_light:

I am still desperately hoping for a solution to the current User Experience fail.


Unfortunately not :frowning: we may need to await the component update

I agree, if you find something, share it with us.

@stayfoolish after the vacations (now) we have a team put together to work on the finalization of e2e plugins – there’s still stuff to be figured out in regards to the whole end to end flow of developing flow functions in this new system, buuuut we’ll get there. And I will definitely be working on draw signature once the pipeline is open :sweat: thanks for being so patient.


Hi Mevi,

hope you had a great time and charged your batteries :battery:!

Thank you for sharing this outlook. I really hope for that update of the draw signature flow function. Please keep us in the loop, as soon as we get one step closer :footprints:

@stayfoolish just to get back to you, I have started to look at the draw signature flow function, but it seems like we will have to change the plugin behind the flow function to begin with to a newer library. Thus when I have done this I will publish a new flow function / component for this. (It’ll still take some time to do this, and naturally I can’t give out any timelines as priorities may shift and unexpected stuff may happen, but just to keep you updated)


Thank you for the update, @Mevi! I really appreciate that you share the status and the hurdles along the way.

Hi Mevi, did you have some time to work on this?

Hi @Mevi

first of all I like to wish you all the best for the new 2023! You and the team did a lot of development in the last year and especially the last couple of month. Thanks a lot for growing the opportunities, which the appgyver platform provides!

Did the recent development also improved the baseline to solve the issues with the ‘draw signature’ flow function? Is there an update you could share with us?

Greetings, I would also love to see this improvement implemented.

Unfortunately I didn’t get the chance to do this improvement due to other priorities :disappointed:
