ButtonThemeData class Null safety

Used with ButtonTheme to configure the color and geometry of buttons.

This class is planned to be deprecated in a future release. Please use one or more of these buttons and associated themes instead:

A button theme can be specified as part of the overall Material theme using ThemeData.buttonTheme. The Material theme's button theme data can be overridden with ButtonTheme.
