      content: SizedBox(
        width: 700,
        child: TextField(
          controller: controller,
          readOnly: !editable,

      actions: <Widget>[
        TextButton(onPressed: () => UClipboard.set(controller.text, snackBar: true), child: Text(U.s.copy)),
        TextButton(onPressed: UNavigator.back, child: Text(U.s.cancel)),
        if (editable) TextButton(onPressed: () => UNavigator.back(controller.text), child: Text(U.s.apply)),
      ],
    ),
