FColors class final

The color tokens.

The main color groups in this scheme are primary, secondary, muted, destructive, and error.

Primary colors are used for key widgets across the UI.
Secondary colors are used for less prominent widgets.
Mute colors are typically used for disabled widgets.
Destructive colors are used for destructive actions such as "Delete" buttons.
Error colors are typically used to highlight errors, such as invalid input in text-fields.

Each color group includes a -Foreground suffixed color, i.e. primaryForeground, used to color text and other visual elements on top of their respective background colors.

Hovered colors are derived by adjusting the lightness of the original color. To derive these colors, use the hover method. The lightness can be adjusted with hoverLighten.

Disabled colors are derived by adjusting the opacity. To derive these colors, use the disable method. The opacity can be adjusted with disabledOpacity.

See FThemes for predefined themes and color schemes.

Methods

copyWith({Brightness? brightness, SystemUiOverlayStyle? systemOverlayStyle, Color? barrier, Color? background, Color? foreground, Color? primary, Color? primaryForeground, Color? secondary, Color? secondaryForeground, Color? muted, Color? mutedForeground, Color? destructive, Color? destructiveForeground, Color? error, Color? errorForeground, Color? card, Color? border, double? hoverLighten, double? hoverDarken, double? disabledOpacity}) → FColors: Returns a copy of this FColors with the given properties replaced.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
override
disable(Color color, [Color? background]) → Color: Returns a disabled variant of the color by multiplying its opacity by disabledOpacity.
hover(Color color) → Color: Generates a hovered variant of the given color by darkening light colors and lighting dark colors based on their HSL lightness.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringShort() → String: A brief description of this object, usually just the runtimeType and the hashCode.
inherited

Operators

operator ==(Object other) → bool: The equality operator.
