FluentButtonStyle class

The visual configuration of a FluentButton.

Deliberately shaped like Material's ButtonStyle: every visual property is a WidgetStateProperty, so hover, pressed, selected and disabled values live on the property rather than being branched on at build time. A Flutter developer already knows how to read and override this.

Every field is nullable and means "inherit". Resolution order, lowest to highest precedence:

the appearance/size defaults derived from the theme
the nearest FluentButtonTheme
the widget's own style

The consumer's own style therefore wins, matching upstream's rule that props.className is passed last to mergeClasses.

Constructors

FluentButtonStyle({WidgetStateProperty<Color?>? backgroundColor, WidgetStateProperty<Color?>? foregroundColor, WidgetStateProperty<Color?>? borderColor, WidgetStateProperty<double?>? borderWidth, WidgetStateProperty<BorderRadius?>? borderRadius, WidgetStateProperty<TextStyle?>? textStyle, WidgetStateProperty<EdgeInsetsGeometry?>? padding, WidgetStateProperty<double?>? gap, WidgetStateProperty<double?>? iconSize, WidgetStateProperty<Size?>? minimumSize, WidgetStateProperty<MouseCursor?>? mouseCursor}): Creates a style. Omitted properties inherit.

Properties

backgroundColor → WidgetStateProperty<Color?>?: Surface fill.
final
borderColor → WidgetStateProperty<Color?>?: Border colour. Null and transparent are different: Fluent's transparentStroke becomes opaque in high contrast.
final
borderRadius → WidgetStateProperty<BorderRadius?>?: Corner radius.
final
borderWidth → WidgetStateProperty<double?>?: Border width. Zero means no border, which is not the same as a transparent one — a zero-width border cannot become visible in high contrast.
final
foregroundColor → WidgetStateProperty<Color?>?: Label and icon colour.
final
gap → WidgetStateProperty<double?>?: Space between icon and label.
final
hashCode → int: The hash code for this object.
no setteroverride
iconSize → WidgetStateProperty<double?>?: Icon edge length.
final
minimumSize → WidgetStateProperty<Size?>?: Minimum tap target.
final
mouseCursor → WidgetStateProperty<MouseCursor?>?: Cursor while hovering.
final
padding → WidgetStateProperty<EdgeInsetsGeometry?>?: Padding inside the border.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
textStyle → WidgetStateProperty<TextStyle?>?: Label text style. Its colour is overridden by foregroundColor.
