Properties
- aspectRatio → double
-
The aspect ratio to crop the image to. Defaults to a square (an aspect ratio of 1.0)
final
- backgroundColor → Color
-
The background color of the cropper widget, visible when the image won't
fill the entire widget. Defaults to a light grey color: Color(0xFFCECECE).
final
-
cropperKey
→ GlobalKey<
State< ?StatefulWidget> > -
The cropper's key to reference when calling the crop function.
final
- gridLineThickness → double
-
The thickness of the grid lines. Defaults to 2.0.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- image → Image
-
The image to crop.
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onScaleEnd → GestureScaleEndCallback?
-
The called when scale end.
final
- onScaleStart → GestureScaleStartCallback?
-
The called when scale start.
final
- onScaleUpdate → GestureScaleUpdateCallback?
-
The called when scale update.
final
- overlayColor → Color
-
The color of the cropper's overlay. Defaults to semi-transparent black
Colors.black54
final
- overlayType → OverlayType
