ButtonTheme class

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

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.
