GradientElevatedButton class
A Material Design "elevated button".
Use elevated buttons to add dimension to otherwise mostly flat layouts, e.g. in long busy lists of content, or in wide spaces. Avoid using elevated buttons on already-elevated content such as dialogs or cards.
An elevated button is a label child displayed on a Material widget whose Material.elevation increases when the button is pressed. The label's Text and Icon widgets are displayed in style's ButtonStyle.foregroundColor and the button's filled background is the ButtonStyle.backgroundColor.
The elevated button's default style is defined by defaultStyleOf. The style of this elevated button can be overridden with its style parameter. The style of all elevated buttons in a subtree can be overridden with the ElevatedButtonTheme, and the style of all of the elevated buttons in an app can be overridden with the Theme's ThemeData.elevatedButtonTheme property.
The static styleFrom method is a convenient way to create a elevated button ButtonStyle from simple values.
If onPressed and onLongPress callbacks are null, then the button will be disabled.
