I am new to sketch and I am looking to make animated gif's like I do in photoshop, Is there a plugin that can do this probably with a timeline too?
I don't think it is possible to have a timeline in Sketch for creating GIF's but please correct me if I'm wrong.
There is a good plugin, which allows you to view images in a art board and in key frames and piece them together in order to create a GIF, so this is probably the sort of plugin you are looking for.
It is known as Generate GIF and I have posted the download link below.
I'm sure there is plenty of videos on YouTube demostrating the use of this plugin.
Please let me know how you get on.
