final

hashCode → int

onChanged → ValueChanged<CropState>

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

showGrid → bool?

Whether the rule-of-thirds grid and the frame border are drawn; by default when interactive. A picker can show them only while the media is touched.
