# Conventions

* `performAction` is internal, `action` is external.
* `computeValue` is internal, `getValue` is external.
  * Recursive calls should use the external variant.
* `adoptChild` and `dropChild` from `AbstractNode` must be called after updating the actual child model to allow the framework to react accordingly.
* Many widgets are comprised of lower-level widgets, generally prefixed with `Raw` (e.g., `GestureDetector` and `RawGestureDetector`, `Chip` and `RawChip`, `MaterialButton` and `RawMaterialButton`). `Text` and `RichText` is an exception.
