title: Is it possible to keep the getters of the reactive form in a seperate file
body: <p>I am having a reactive form that has multiple form controls. For each form each control i have written a getter function which will get the name of the form control like below</p>
  <pre><code>get interface() {
    return this.deviceQosForm.get('interface');
  }
  </code></pre>
  <p>Form:</p>
  <pre><code>this.deviceQosForm = this.formBuilder.group(
        {
          interface: [null, Validators.required],

          class_id: [null, [Validators.required, classMinMax]],
          class_name: [
            null,

  <p>Like this i am having around 50 getter functions inside the component.I would like to know whether this getter can be moved to a separate file.Is it a good practice to do</p>
