ChangeColors class

Use the ChangeColors widget to change the brightness, saturation and hue of any widget, including images.

Example:

ChangeColors(
   hue: 0.55,
   brightness: 0.2,
   saturation: 0.1,
   child: Image.asset('myImage.png'),
);

To achieve a greyscale effect, you may also use the ChangeColors.greyscale constructor.

Constructors

ChangeColors({Key? key, double brightness = 0.0, double saturation = 0.0, double hue = 0.0, required Widget child})
ChangeColors.greyscale({Key? key, double brightness = 0.0, required Widget child})

brightness → double: Negative value will make it darker (-1 is darkest). Positive value will make it lighter (1 is the maximum, but you can go above it). Note: 0.0 is unchanged.
final
child → Widget: final
hashCode → int: The hash code for this object.
no setterinherited
hue → double: From -1.0 to 1.0 (Note: 1.0 wraps into -1.0, such as 1.2 is the same as -0.8). Note: 0.0 is unchanged. Adding or subtracting multiples of 2.0 also keeps it unchanged.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
saturation → double: Negative value will make it less saturated (-1 is greyscale). Positive value will make it more saturated (1 is the maximum, but you can go above it). Note: 0.0 is unchanged.
final

build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.
