Can we use @InputBoolean() instead of getter?

<nz-form-label nzLabelWrap></nz-form-label>

Also you need to rebase this with the master branch.

okay👌🏻

Can we use @InputBoolean() instead of getter?

<nz-form-label nzLabelWrap></nz-form-label>

If the nzLabelWrap of the NzFormLabelComponent has no value, we
need to get the nzLabelWrap of the Form Directive, so i think we need to use getter

[simplejason]

@InputBoolean() will automatically set this property to be true, check other components that use this decorator like select
