How to fix Flutter animations, shader compilation jank problem, how to use SkSL warmup, pre Impeller
In this tutorial, we will see how we can fix flutter animations on iOs devices during the first run. I'll show a real-life application before and after the optimization, and we will do optimization in two ways - manual and automatic.
This video has the purpose of demonstrating the optimization technic, but it's still highly recommended to go through the docs in order to understand the issue.
May be not relevant after Impeller rendering runtime release.
