A custom image cropper widget

Properties

backgroundColor → Color
The color behind the cropping area
final
borderRadius → double
The radius for rounded corners of the cropping area (only applicable to rounded rectangle shapes).
final
canMove → bool
Determines whether moving gesture overlay is disabled.
final
canRotate → bool

final
canScale → bool
Determines whether scaling gesture is disabled.
final
clipShapeOnCrop → bool
Whether to clip the area outside of the path when cropping By default, the value is true
final
cropController → GnkImageCropController
The controller that handles the cropping and changing of the cropping area
final
cropPercentage → double
The percentage of the available area that is reserved for the cropping area
final
customProgressIndicator → Widget?
This widget is used to specify a custom progress indicator
final
drawPath → CustomPaint Function(Path, {Paint? pathPaint})
The path drawer of the border see DottedCropPathPainter, SolidPathPainter for more details or how to implement a custom one
final
forceInsideCropArea → bool
Whether image area must cover clip path By default, the value is false If use CustomCropShape.circle, the cropped image may have white blank.
