Final field 'contentPadding' is not initialized.

I am getting this error, 'contentPadding' is not initialized.
Try to initialize the field in the declaration or in every constructor.
final EdgeInsetsGeometry contentPadding;

the issue is resolved in the master branch, you guys already have this in constructor
this.contentPadding = const EdgeInsets.symmetric(horizontal: 20.0),
but the published version cool_stepper: ^1.2.1 doesn't have this, please publish the master branch.
