Use Kotlin Multiplatform to share most of the code.

Why Cross-Platform?Īs the project required dealing with low-level graphics and it being the huge portion of the app, React Native and Flutter didn’t fit our use case and it’s just too much overhead to build the app with C++ as experienced by folks at DropBox (read more about it in the article by Eyal Guthmann). That’s when we started exploring available multiplatform solutions. All this with a small team of mobile developers, so we need to come up with a solution that could help us build the apps faster and avoid writing complex code multiple times for different platforms. It deals with everything apart from rendering like networking, local storage, file operations, authentication, notifications, analytics, crash reporting, media pickers, complex video editing UI, user interactions, and interfacing with the Editor.Īs you can tell, this is a very different app from a regular CRUD app, especially the Renderer and we had limited time and resources to build an app that’s stable, has high performance, consumes minimal resources, and provide a good user experience regardless of the device specifications. Platform The user-facing part implementing a beautiful, easy-to-use UI optimized for various screen sizes and device constraints.It needs to handle media encoding and decoding and have a smart resource caching system to provide an optimal user experience with minimal resource consumption. Editor/Renderer Deals with graphics rendering using OpenGL, Vulkan, or Metal, with the ability to render media elements namely image, video, audio, text, stickers, and fonts with support for effects, filters, animations, and transitions.It’s a fairly complex project dealing with lots of graphics and business logic and can be broadly divided into 2 parts:

We need to build apps for Android and iOS with a similar feature set as the web providing the users with advance video editing capabilities. InVideo has a feature-rich Web client and wants to bring the same power to everyone regardless of the device.
