RawMaterialButton class Null safety

Creates a button based on Semantics, Material, and InkWell widgets.

This class does not use the current Theme or ButtonTheme to compute default values for unspecified parameters. It's intended to be used for custom Material buttons that optionally incorporate defaults from the themes or from app-specific sources.

This class is planned to be deprecated in a future release, see ButtonStyleButton, the base class of TextButton, ElevatedButton, and OutlinedButton.
