ChangeColors class Null safety

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})

Properties

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.
@nonVirtualread-onlyinherited
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.
read-onlyinherited
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.
