v 1.2.1


A few critical bugs popped up since our recent release. This is a hot-fix to address some of them.

Crushed Bugs
We crushed the following:

  • A crash occurring when dragging Artboards in sketch import process.
  • A crash occurring when importing sketch files which contain combined shapes which themselves contain combined shapes
  • A crash occurring when copy pasting layers from sketch which contain combined shapes which themselves contain combined shapes

There are a couple more bugs we are currently crushing, and when they’re well crushed, smashed, pulverized, we’ll release again… Hopefully in a few days.

1.2 (11/22/18)

Some much needed UI treatments, a bit of smooth polish, and quite a bit of tidying up.

We tuned up a lot of the interface and how things work. Here are the things we added:

  • A more obvious state for Relative Mode.
  • The ability to show / hide titles on the toolbar.
  • Playhead snapping to the scrubber on the touch bar.
  • The ability to select a range of time to review on the timeline ruler.

And, the things we fixed:

  • Separated transform into two lines called rotation and anchor point in properties panel.
  • Properly update colors when toggling between dark mode and light mode.
  • Hierarchy view selection colours were messed up, now they’re better.
  • Update lock icon in properties panel.

Thanks @AS for your help on identifying a few small improvements that made a great difference.

To make life a touch smoother, a tiny bit more pleasant, and a little better in general, we:

  • Updated the document creation workflow.
  • Prevent the activation window from constantly popping up.
  • Let you skip to the in / out points of selected track animations (see the new commands below).
  • Introduced separate time ranges for each timeline.
  • Disable export when there are no timelines in a project document.

We dramatically improved the performance of the app when:

  • Dragging many key values at once in the timeline.
  • Scrolling & Zooming the timeline with many tracks.

Thanks to @JMcK for the heads up on these two points.

New / Updated Commands
A couple of subtle touches / new key commands will let you do the following:

With layer(s) selected on the stage…

  • Pressing U will expand / hide the tracks for those layers in the timeline.

With layer(s) or track(s) selected on the timeline or the stage…

  • Pressing I will jump the timeline playhead to the FIRST key value of the selection.
  • Pressing O will jump the timeline playhead to the LAST key value of the selection.

When the Time Range selector is smaller than the entire timeline…

  • Pressing CMD+Left will jump the timeline playhead to the START handle of the selection.
  • Pressing CMD+Right will jump the timeline playhead to the END handle of the selection.

A small change…

  • Toggling Relative Mode is now done with CMD+OPTION+R (we’re queuing up a new command for CMD+R)

Getting things to code…

  • Fix placement issues in iOS when exporting a certain size artboard and running it in a different size device simulator
  • Export fill images in iOS.
  • Add support for testing Export more thoroughly.

File Size
Our files were a bit chunky before. So we reduced the size of Flow files by storing image hashes instead of data blobs.

Crushing Bugs
We absolutely crushed these bugs…

  • A sneaky one that was preventing the creation of font and font size tracks.
  • A snarky that was preventing proper undoing of timeline scaling command.
  • A tiny one whose job it was a to not update the timeline ruler when scrolling in timeline.
  • A beautiful one that really only ever wanted to see Flow crash when resizing images.
  • A lazy one that really wanted scrolling to be slow when choosing a sketch file in finder.
  • A confusing one that wanted buttons to be on top of one another.
  • A slightly obscure one that tried to mess with the timeline hand dragging tool icon.

1.1.1 (10/18/18)

This week’s retrospective. “Hey, Travis, can you polish up the colours and UI for Mojave?” “Sure thing.” »> Deletes critical UI component and introduces a critical bug right before shipping.

1.0.4 (09/4/18)

An update to the HTML – and a few other things.

HTML Export

We launched with a strong iOS export. Here, we make amends to all the lovely web people who have given Flow a run for its money:

  • Don’t include empty css animation blocks in html export for non-animated layers
  • Fix anchor point animations in html.
  • Add ability to export animation tracks with multiple keyvalues in html
  • Add ability to export step function easing curves in html fix border width animations in safari and chrome
  • Fix rotation export in HTML
  • Fix exporting flipped vertical and flipped horizontal properties in html export

There’s more HTML improvements on the way, but this is a pretty decent step for now.


And, a few SVG updates to accompany the ones above:

  • Don’t scale width of border when scaling SVG
  • Fix SVG scaling
  • Adjust SVG path string precision

iOS Export

A bit of a tune-up for iOS export:

  • Patch strokeEnd Animation bug in iOS export
  • Correctly animate border width in iOS export
  • Export images into iOS as 1x
  • Set initial corner radius of layers in exported ios projects
  • Fix exporting contentMode in iOS export


To make Flow just a little bit more lovely to use, we improved the following things:

  • Prevent insert shape drop down menu icon from being cut off
  • Allow zooming of timeline with track pad
  • Allow users to create timelines using one artboard
  • Fix the checkboxes in the export panel so that clicking on their associated titles checks/unchecks the check box.
  • Update code preview when switching to new timelines
  • Add border color, border radius and border width code snippets to CodePreview


Tuning up how to spit out code:

  • Move to the trash any previously exported timelines when reExporting the same Flow document
  • Support exporting content mode of image layers in iOS and HTML
  • Support exporting borders in iOS and HTML

  • Stopped drawing easing curves if there’s no space between keyvalues

User Experience

The things that will make you smile, a.k.a the things that would make you not smile if they weren’t there.

  • You can now increment layer property values by pressing up and down keys while your cursor is in their textfields on the properties panel.
  • You can also increment in the keyvalue time fields
  • Created a nice way of translating dev-speak to friendly language for error and alerts that pop up.\
  • We now center the main artboard to the stage when switching between timelines, or opening new files.
  • Add relative mode button that lets you change the values across all keyvalues for a property throghout the entire timeline.
  • You can now snap the playhead to keyvalues on the timeline
  • Fixed up how keyvalues snap to tick marks in the timeline header

  • Collapse and expand track views appropriately when switching focus to a new Timeline.
  • Save flow version used to create flow file in .flow file
  • Only show permissible easing curve functions in multi-keyvalue properties panel
  • After copying keyvalues, you can now paste in place

Quasi-UX stuff

  • MEGA performance increase by improving the signals infrastructure
  • Improved stage performance when handling all timeline changes
  • Improve sound track drawing performance

Exporting Media

Here’s what we did to help you get media OUT of Flow…

  • GIFs!
  • You can also export the current frame as PNG.
  • Updated the compression settings for MP4 to Apple ProRes4444 / .mov < better quality than before.
  • Hidden layers were getting through, now they down when exporting to Gif, PNG or movies

Exporting Software

  • Added crypto utilities and verify digital signatures
  • Added launch story board to exported iOS projects
  • Added a block to suppress animations when creating views in a ViewController
  • Added an app icon to exported iOS projects
  • Export layer flipping on iOS (sometimes things were upside-down)
  • Add even-odd fill rule on export (now you can have complex shapes with holes cut out properly)
  • Timeline you’re exporting now gets slipped into a view that is centered in the exported iOS project
  • Dash offset values are now exported

Bug Fixes (General)

  • Set max duration for sound tracks to 30s (sorry, you won’t be able to listen to Over the Hills and Far Away)

Path Handling

There’s only a few bullet points in this one, but it was a lot of work that made Flow immensely better…

  • Add path equalization to enable path animations
  • Use normalized paths everywhere


0.7.2 (06/29/18)

A little hot fix for your Friday afternoon.


Thanks to some lovely feedback we received today, we found that we weren’t properly importing shadows from Sketch, or exporting them to code.

  • Set default shadow opacity so shadows are visible in Flow after importing.


0.7.1 (06/26/18)

Are you thinking to yourself… “Didn’t they update yesterday?”

Yessss we did.


There was a bug on the timeline that we found shortly after releasing.

  • Fixes an area selection bug where keyvalues weren’t being selected after scrolling downwards quite a ways (for animations with lots of tracks).


0.7.0 (06/25/18)

Right, so usually I like to try and organize these release notes into categories so you can see a little easier just what we’ve been up to. Buuuuut, this time… there’s just too much, and I’m on my second cup of coffee, and there’s about 10 other things to do, and we’re trying to get to a V1.0 in a few weeks, so really…

The big news is…


This one is so butter. We’ve rebuilt the timeline so that it can handle 2 mega things:

  • Zooming! - Yes, you can zoom in an out.
  • Area Select! - MMMMMM, you can use your mouse to select a bunch of key values.

The timeline is so sweet now.


Also another biggie. We’ve dramatically improved performance. It’s not easy balacing time and space, but we hope this new version is definitely less beachbally than the previous release.

0.6.0 (05/19/18)

Another wicked release coming your way, brought to you by the lovely Flow team.

Sketch Fixes

Sketch 50 beta came out, and things broke again, but we fixed them:

  • Importing paths
  • Importing images
  • Importing text layers All work again.

Multi-Keyvalue Selection

Like music to my ears. This is one I’ve been waiting for for a long time.

  • You can select multiple key values.
  • And copy them…
  • And paste them…
  • Which requires some backend majique to remove redundant keyvalues
  • And also requires a much needed Multiple Keyvalue info panel
  • To make things easier we created some backend copy / paste helpers
  • Made sure the easing curve option ignore keyvalue pairs with the same value
  • Improved copy infrastructure

A New Step Curve

Ever feel like you just wanted to be somewhere else right now? Well, until today, so did keyvalues. Now you can set a special kind of curve between two keyvalues that makes them JUMP from one value to the other without animating. It’s like saying “Don’t animate between 10 and 20”, and it’s lovely.

  • Adds step curve option for animations
  • Support step animation in HTML export
  • Support step animation in iOS export
  • Adds color-tone change to track areas where steps happen


And for some lovely improvements to the user experience and interface:

  • Resize group layer when sublayer is deleted
  • Expand group in hierarchy view after undo brings back group
  • Remove jump when changing anchor point
  • Code preview works for multiple selection on hierarchy view
  • Made send feedback button in main window work again
  • Delete tracks in timelineview when deleting a layer
  • Resize scenes if too small in sketchImport window
  • Fix selection box problems
  • Prevent deletion of layers if dragging
  • Prevent skipping around in timeline while dragging on stage
  • Generate code if code preview is brought up


The things we fixed when exporting your animations to code:

  • Round values on export
  • Export Images with the same name
  • Fix image and font changes on exported HTML
  • Made finish export only occur after export finishes
  • Prevent playing animation while mouse is down
  • Fix gradient export
  • Fix mask export for iOS



  • Store images by hash in image catalog
  • Clear out test files for release < lightens the load
  • Fix group resizing when rotated
  • Fix problem when dragging too far with locked aspect ratio
  • Update gradient mask when necessary
  • Fix crash when resizing


I’m going to be honest here, if you grouped layers then had a good time with them, then decided they didn’t really get along and that they probably shouldn’t be in the same group, then you ungrouped them…. well, honestly, we used to just destroy all your hard work.

  • Grouping used to destroy animations. Now it doesn’t.


0.5.0 (03/16/18)

Ok, this release is so big I’ve got to break it up into little bits…


The major reason for taking so long to get back to you with a really great update is that we completely rebuilt our code export pipeline to use templates. This approach makes it “super” easy to customize the code output of Flow into ANY LANGUAGE YOU CAN THINK OF (probably even Latin).

Here’s what we added and fixed for export:

  • Added templates < wham.
  • Added HTML template
  • Added HTML/CSS animation export
  • Rebuild iOS export
  • Added exporting sounds (iOS) 🎶
  • Smart font exporting (iOS) - don’t export system font files, or files specified at www.iosfonts.com
  • Fixed exporting text and attributed strings
  • Fixed a reset issue for the timeline in an exported project (iOS)
  • Fixed how we handle horizontal and vertical flips / scaling in animations (iOS)
  • Fixed path rotation export - sets values instead of incrementing them.
  • Fixed path animation export
  • Added support for exporting masks (iOS)
  • Remove old codegen framework
  • Use new monolithic interface for Flood (TBH I have no idea what that means, but it’s by far the best commit title for this releasae!)


We updated a few things in the interface, however more of this will be apparent in the NEXT release:

Here’s what we added and fixed for UI:

  • Made parent tracks look like child tracks (renders keyvalues into parent tracks, adds gaps, etc…)
  • Added a new export panel UI
  • As a user you can more easily move keyvalues between, or on top of other values
  • Updated the team list in the welcome window
  • Initiate code export with a key combo: CMD+E
  • Added a Send Feedback help menu item
  • Updated a link to tutorials
  • Made the eye / lock icons share a single column (option key toggles between them)
  • … AND
  • Added the ability to drag and drop layer rows in the hierarchy panel!!@!@#!@#! (@jerbear poured a lot of bsat into this to make it tip-top)


We did our best to take all the great feedback and improve on some critical issues.

Here’s what we added and fixed for UX:

  • Fixed the hide / lock button behaviour
  • If an animation is running and you change something, the timeline will now pause
  • Disabled the ability to accidentally right-click while dragging a keyvalue
  • Image tracks do not get generated if there is no change between artboards (this was actually quite tricky because they’re treated like completely separate objects even though they may look identical)
  • Fixed the re-expansion of the timeline (e.g. after undoing)
  • Fixed the resizing of groups
  • Fixed a small problem with layers having the same name
  • Added backwards compatibility for text color changes in old Sketch files
  • Prevent a silly and almost utterly unintelligible error dialog when exporting and overwriting folders
  • Wrote a much nicer, friendly, and generally more eloquent error message when loading old Sketch files
  • Fixed some issues with undoing of group move actions
  • Fixed / re-added the deletion of keyvalues
  • Fixed code preview (we lost it along the way)


We tried to make things a little smoother as well.

  • Put the rendering of code preview on a background thread.
  • Increased responsiveness of the app when selecting many layers at the same time.


This is a bit like UX, because don’t you just hate it when things don’t look the way you want them to?

Here’s what we added and fixed for Sketch Import:

  • Extracted Sketch Kit (our lib for importing / handling Sketch files) into seperate library
  • Updated Flow to read Sketch version 49 files - I really wish we knew the future and could anticipate their releases
  • Fixed importing of text color
  • Fixed mask animation importing
  • Remove UUID from Keyvalues (thanks for the tip > @andydent)
  • Handle things better when a user has chosen artboards which don’t match
  • Handle pattern fill types


We added hundreds and hundreds of automated tests to help us keep things stable so your creativity can keep on Flowing. (By “we” I mean Kobe and Joel)


We added a help window – and some content, but not a lot of content, because we’re a small team, and we’re trying hard, very hard, to bring you a great tool, so we have to spread ourselves a bit thin, but we’re doing our best.


0.4.4 (03/2/18)

Two small fixes to catch up with the latest file versions in Sketch:

  • Updated import to handle Sketch 49 file format
  • A kiss from Jeremie

0.4.3 (02/8/18)

A couple of small fixes to catch up with the latest file versions in Sketch:

  • Updated import functionality to properly “handle” slices on images
  • Updated import for text color
  • New, more clear layout for the .dmg (now it makes sense)

0.4.2 (10/29/17)

  • Removes group layers when they become empty
  • Draws shapes into the layer hierarchy (mmmmmmm)
  • You can now select layers – in the hierarchy panel – that are locked or hidden… This doesn’t select them on the stage.
  • Keeps all your selected rows selected when the document is refreshing (otherwise this would be really annoying).
  • You can only edit properties of selections if they’re unlocked and visible.
  • You can’t Ducplicate anymore, but you can Duplicate (thx @Michael Franco).
  • Fixes the generation of SVG code, it’s prettier now.
  • Prevents the exporting of iOS standards fonts (per: iosfonts.com).
  • Minimum build is now OSX 10.11 (thx @Martin von Siebenthal).

0.4.1 (10/23/17)

  • Update the brand! New app logos galore ;)
  • Adds a nice button for toggling the visibility of layers that are off of the main artboard.
  • Updated the look of thumbnails via a lovely QuickLook plugin.
  • Lots of visual polishing on the Hierarchy Panel.
  • Prevent deleting an object when deleting a track in the timeline.
  • Update parent tracks based on child track length in the timeline viewer.
  • Update links to external sites and email addresses, they now use createwithflow.com ;)
  • Track views show markers for key values in their child tracks.
  • Fixes for using custom fonts.
  • Keep timeline open while refreshing the document (i.e. so it doesn’t collapse all the time).
  • Fixes a bug where editing text in the property field crashed the application.
  • Update colors for selected tracks in timeline viewer.
  • Hots up the hierarchy view by adding custom icons depending on the layer type.
  • Puts some much needed love into how the eye / lock icons work in the hierarchy panel.
  • Fixed a bug where groups wouldn’t have opacity applied during import.
  • Fixes an error when exporting code with custom fonts.
  • Fixes a crash caused by an invalid layer state.
  • Makes an error message more palatable – for ensuring duplicate artboards have the same hierarchies.
