ButtonBarThemeData({MainAxisAlignment? alignment, MainAxisSize? mainAxisSize, ButtonTextTheme? buttonTextTheme, double? buttonMinWidth, double? buttonHeight, EdgeInsetsGeometry? buttonPadding, bool? buttonAlignedDropdown, ButtonBarLayoutBehavior? layoutBehavior, VerticalDirection? overflowDirection}): Constructs the set of properties used to configure ButtonBar widgets.
const

alignment → MainAxisAlignment?: How the children should be placed along the horizontal axis.
final
buttonAlignedDropdown → bool?: If true, then a DropdownButton menu's width will match the ButtonBar button's width.
final
buttonHeight → double?: The minimum height for ButtonBar buttons.
final
buttonMinWidth → double?: The minimum width for ButtonBar buttons.
final
buttonPadding → EdgeInsetsGeometry?: Padding for a ButtonBar button's child (typically the button's label).
final
buttonTextTheme → ButtonTextTheme?: Defines a ButtonBar button's base colors, and the defaults for the button's minimum size, internal padding, and shape.
final
hashCode → int: The hash code for this object.
read-onlyoverride
layoutBehavior → ButtonBarLayoutBehavior?: Defines whether a ButtonBar should size itself with a minimum size constraint or with padding.
final
mainAxisSize → MainAxisSize?: How much horizontal space is available. See Row.mainAxisSize.
final
overflowDirection → VerticalDirection?: Defines the vertical direction of a ButtonBar's children if it overflows.
final
runtimeType → Type: A representation of the runtime type of the object.
