When set to
true, the user is forced to crop the asset to one of the
allowed crop ratios in
transform.items before being able to use other
features of the editor.
The transform tool will only be presented if the image does not already
fit one of the allowed aspect ratios. It will be presented automatically,
if the user changes the orientation of the asset
and the result does not match an allowed aspect ratio.
This property has no effect unless
transform.allowFreeCrop is set to
// Defaults to: false
final bool forceCrop;
