How to watch when the Slidable changes state on Flutter - flutter

Question

I'm utilize o Slidable on app Flutter and put as ListTile child.
So far ok.
I'm problem is i would like when I slide it to the left the text keeps appearing on the screen, as shown in the image below.(Red == Title)
At the moment the text is hidden when I swipe, as per the image.(Red == Title)
I saw that when I swipe this attribute changes state Slidable.of(context)?.animation.isCompleted
And I also verified that in my Row title of ListTile, if I line up the title as End, the title will appear msm by swiping.
So I thought, as this Slidable.of(context)?.animation.isCompleted attribute changes state I align my Row to Start or End.
But I couldn't find a way to monitor this attribute, so that when it changes I can rebuild my Row. I tried to put it as Stream but I wasn't successful. Because it looks like it doesn't generate an event, it just changes the value.
I don't know how I could do it, if anyone has any tips...
Code:
#override
Widget build(BuildContext) {
return Slidable(
key: const ValueKey(1),
endActionPane: ActionPane(
motion: const DrawerMotion(),
children: [
SlidableAction(
onPressed: (ctx) => {
Get.to(() => const CredentialOperationScreen(),
arguments:
RouteDetailCredential(itemCredential: itemCredential))
},
backgroundColor: ConstsColors.orangeAccent,
foregroundColor: Colors.white,
icon: Icons.info_outline,
),
SlidableAction(
onPressed: (ctx) => {
Get.to(() => const CredentialOperationScreen(),
arguments:
RouteDeleteCredential(itemCredential: itemCredential))
},
backgroundColor: const Color.fromRGBO(219, 32, 32, 1),
foregroundColor: Colors.white,
icon: Icons.delete_outline,
),
],
),
child: Builder(
builder: (ctx) {
return Container(
child: _listTile(ctx),
decoration: const BoxDecoration(
border: Border(
bottom:
BorderSide(color: ConstsColors.greyColorOpacity))));
},
));
}
Widget _listTile(context) {
return ListTile(
title: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Icon(
itemCredential.icon,
color: Colors.black,
),
Padding(
padding: const EdgeInsets.only(left: 8.0),
child: Text(
itemCredential.name,
style: const TextStyle(
fontFamily: 'Roboto',
fontSize: 16,
),
),
),
],
),
onTap: () => {
Slidable.of(context)?.animation.isCompleted == true
? Slidable.of(context)?.close()
: Slidable.of(context)?.openEndActionPane()
},
trailing: const Icon(Icons.check_circle_outline, color: Colors.green),
);
}
