Creating custom item renderers for the Feathers List, DataGrid, Tree and GroupedList components (Starling version)
The default item renderers provide an abundance of customization options to display up to three children with a variety of layouts. However, sometimes, you need more children or more advanced layout capabilities to translate a design to code for a customized list. In those situations, you may need to create a custom item renderer class.
Custom item renderers are basically custom Feathers components. When you create a custom item renderer, you will be working at a low level inside the Feathers architecture. Ideally, you should understand the internals of Feathers components before proceeding.
