Flutter: Too many positional arguments: 0 expected, but 3 found - flutter

Question

I'm new to flutter. I don't know how to solve this error. Please help
class HomePage extends StatelessWidget {
Widget _textformField(){
return Padding(
padding: EdgeInsets.only(right: 10),
child: TextFormField(
decoration: InputDecoration(
fillColor: Color(0xff3a3e3e),
filled: true,
hintText: "Search Food",
hintStyle: TextStyle(color: Colors.white),
prefixIcon: Icon(Icons.search,color: Colors.white,),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(10.0),
borderSide: BorderSide.none,
),
),
),
);
}
_textformField(),
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: [
_allCategories(
image: 'images/Ayam-Goreng.png',
title: 'Ayam Goreng',
),
_allCategories(
image: 'images/Ayam-Kari.png',
title: 'Ayam Kari',
),
I got "too many positional arguments: 0 expected but 3 found" error when calling _textformField() function on line 191.
I tried removing all of the textformField widget but then the error moves to SingleChildScrollView()
SingleChildScrollView(
scrollDirection: Axis.horizontal,
child: Row(
children: [
_allCategories(
image: 'images/Ayam-Goreng.png',
title: 'Ayam Goreng',
),
_allCategories(
image: 'images/Ayam-Kari.png',
title: 'Ayam Kari',
),
My _allCategories code:
Widget _allCategories({required String image, required String title}){
return Container(
height: 130,
margin: EdgeInsets.symmetric(horizontal: 10),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
height: 70,
width: 70,
decoration: BoxDecoration(
color: Colors.grey,
image: DecorationImage(
fit: BoxFit.cover,
image: AssetImage(image),
),
borderRadius: BorderRadius.circular(10.0)
),
),
Text(title,style: TextStyle(fontSize: 18, color: Colors.white),)
],
),
);
}
My _bottomCategories code:
Widget _bottomCategories({required String image, required String title, required double price}){
return Container(
decoration: BoxDecoration(
color: Color(0xff3c3f40),
borderRadius: BorderRadius.circular(20.0)
),
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 15),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
child: Center(
child: CircleAvatar(
backgroundImage: AssetImage(image),
radius: 60,
backgroundColor: Colors.transparent,
)
),
),
Container(
height: 50,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(title,
style: TextStyle(
fontSize: 15,
color: Colors.white,
fontWeight: FontWeight.bold
),
),
Text(
'\$ $price',
style: TextStyle(
fontSize: 15,
color: Colors.white,
fontWeight: FontWeight.bold
),
),
],
),
Row(
children: [
Icon(
Icons.star,
size: 14,
color: Colors.white,
),
Icon(
Icons.star,
size: 14,
color: Colors.white,
),
Icon(
Icons.star,
size: 14,
color: Colors.white,
),
Icon(
Icons.star,
size: 14,
color: Colors.grey,
),
],
),
],
),
),
],
),
),
);
}```
Any help is appreciated! Thanks!
