How to add a File Picker plugin in Flutter?

In WinRT, how do I load an image and then wait only as long as is needed for it to load before writing to it?

我与影子孤独终老i 提交于 2019-12-01 07:57:59
问题 I'm using WriteableBitmapEx in a WinRT project. I load an image into a WriteableBitmap from the users Picture library. However, I cannot then immediately write to that image, if I do, it will be overwritten with the image itself (it seems like it's Async loading the image and then it's overwritting my drawing on top of it). I don't know how to stop it from doing that (I tried using Await on the SetSource but that's not an Async method). I've used an "Await Task.Delay(1000)" and that works,
