value of the title and description repeats every time a new todo is made - flutter

Question

I just started learning flutter and am trying to create a todo app, but every time a new todo is made the value of the title and the description remains the same for all the todos,
I have tried every method but no difference pls tell me what's wrong with the code and how do I save the value of the title and description for each todo?
My code:
class _HomePageState extends State<HomePage> {
TextEditingController _titleController = TextEditingController();
TextEditingController _detailController = TextEditingController();
List todos = [];
#override
void initState() {
super.initState();
todos.add('');
}
#override
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 Dismissible(

Hello and welcome to the world of flutter,
like you do for title and detail, every textfield needs it's own TextEditingController. So you could add a list of controllers for title and description.
List<TextEditingController> _titleController = [];
List<TextEditingController> _detailController = [];
and add an entry to both, when you add todo.
todo.add('')
_titleController.add(TextEditingController())
_detailController.add(TextEditingController())
At the TextFields you should reference by index:
...
child: TextField(controller: _detailController[index],
...
This should help with your problem.
I would recommend you to look at some tutorials and try to rebuild them.
Have fun!
