Flutter Dismissible background goes up after list item is dismissed - flutter

Question

I just started learning flutter and am trying to build a todo app, the problem I encountered was the widget buildActionSwipeLeft() set as dismissible background goes up rather than left to right after the list item is dismissed although I set the direction of the dismissible from left to right or start to end. Any help would be appreciated.
My code:
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Container(
width: double.infinity,
padding: const EdgeInsets.symmetric(
horizontal: 24.0,
),
color: const Color(0xfff6f6f6f6),
child: Stack(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
margin: const EdgeInsets.only(bottom: 32.0, top: 32.0),
child: const Text(
"Reminders",
style: TextStyle(
fontSize: 25.0,
fontWeight: FontWeight.bold
),
),
),
Expanded(
child: ListView.builder(
itemCount: todos.length,
physics: const BouncingScrollPhysics(),
itemBuilder: (BuildContext context, int index) {
return Padding(
padding: const EdgeInsets.only(
bottom: 15.0
),
child: Card(
color: Colors.white,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(16),
),
elevation: 4,
child: ClipRRect(
clipBehavior: Clip.antiAlias,
child: Dismissible(
background: buildActionSwipeLeft(),
onDismissed: (direction) {
setState(() {
todos.removeAt(index);
_titleController.removeAt(index);
_detailController.removeAt(index);
});
},
direction: DismissDirection.startToEnd,
key: UniqueKey(),
child: Container(
width: double.infinity,
padding: const EdgeInsets.symmetric(
vertical: 13.0,
horizontal: 24.0
),
margin: const EdgeInsets.only(
bottom: 20.0,
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
TextField(
cursorColor: Colors.black,
controller: _titleController[index],
style: const TextStyle(
fontSize: 22.0,
fontWeight: FontWeight.bold
),
decoration: const InputDecoration(
hintText: "Enter a title",
border: InputBorder.none,
),
),
const Divider(
color: Colors.black,
),
Padding(
padding: const EdgeInsets.only(top: 0.0),
child: TextField(
controller: _detailController[index],
style: TextStyle(
fontSize: 20.0,
color: Colors.grey[900],
),
cursorColor: Colors.black,
maxLines: null,
decoration: const InputDecoration(
hintText: "Enter the description",
label: Text("description"),
border: InputBorder.none
),
),
),
],
),
),
),
),
),
);
},
),
)
],
),
Positioned(
bottom: 24.0,
right: 0.0,
child: GestureDetector(
onTap: () {
setState(() {
todos.add('');
_titleController.add(TextEditingController());
_detailController.add(TextEditingController());
});
},
child: Container(
width: 60.0,
height: 60.0,
decoration: BoxDecoration(
color: Colors.black87,
borderRadius: BorderRadius.circular(20.0),
),
child: const Icon(Icons.add, color: Colors.white, size: 35.0),
),
),
)
],
),
),
),
);
}
}
Widget buildActionSwipeLeft() => Container(
alignment: Alignment.centerLeft,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(16.0),
color: Colors.redAccent,
),
padding: const EdgeInsets.symmetric(horizontal: 30),
child: const Icon(Icons.delete, color: Colors.white, size: 30),
);

Answer 1

I figured out that this was not an issue as this is the default animation thats played when a list tile wrapped in a dismissible widget is dismissed. And the dismiss direction just determines the direction in which you can swipe the widget and not the direction in which the widget animates after dismissal.
