  • Polish to the DevTools footer - #3989, #4026, #4041, #4076

Performance updates

#

  • Added a new feature to help you debug raster jank in your Flutter app. This feature allows you to take a snapshot of the current screen shown in your app, and then break down rendering time for that scene by layer. This can help you identify parts of a scene that are expensive to rasterize - #4046
