ButtonTheme class Null safety

Used with ButtonThemeData 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.

The actual appearance of buttons depends on the button theme, the button's enabled state, its elevation (if any), and the overall Theme.

  • RawMaterialButton, which can be used to configure a button that doesn't depend on any inherited themes.
