Use case

If I have a TextField widget that uses a suffixIcon, but the text field has enabled: false, the suffixIcon is not interactable, even though it has an onPressed set.

Example:

TextField(
  enabled: false,
  decoration: InputDecoration(
    suffixIcon: IconButton(
        onPressed: () {
           print('pressed');
        },
        icon: Icon(Icons.edit_outlined, size: 20, color: Colors.blue),
    )
  ),
)

I tried setting the enabled state of the InputDecoration, but that didn't help.
Per the docs:

If false helperText, errorText, and counterText are not displayed, and the opacity of the remaining visual elements is reduced.

Proposal

Let the suffix icon handle its enabled state separately from the text field's enabled state. Maybe by allowing it to read the enabled state separately from the InputDecoration, without looking at TextField.enabled ?
