How To Delete The Row In List In Flutter

Hello guys, Today we learn about “How To Delete The Row In List In Flutter“.

In Flutter, we are using ListView to show the listing data in a row. And sometimes we need to implement the delete functionality, for example, I have a four-row in the list but I want to delete any one row in the list on that time I am implementing the delete functionality in Flutter.

Getting Started:-

Step 1:- First, Create your Flutter Project from Android Studio or Visual studio code.

Step 2:- Now, implemented the simple list view in Flutter

import 'package:flutter/material.dart';
void main() {
  runApp(
    MaterialApp(
      home: MyApp(),
    )
  );
}

class MyApp extends StatefulWidget{
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  List<EmployeeData> employe= [];

  @override
  void initState() {
    
    employe.add(EmployeeData(empid:"108-01", empName:"Aman Bhatt", phoneNumber:"1234567890", country:"USA"));
    employe.add(EmployeeData(empid:"108-02", empName:"Riya", phoneNumber:"0987654321", country:"India"));
    employe.add(EmployeeData(empid:"108-03", empName:"Karan", phoneNumber:"7869805432", country:"India"));
    employe.add(EmployeeData(empid:"108-04", empName:"Rihana", phoneNumber:"8976543210", country:"China"));
    
    super.initState();
 }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
          appBar: AppBar(
              title:Text("Employee List"),
              backgroundColor: Colors.green,
          ),
          body: SingleChildScrollView( 
            child: Container( 
              padding: EdgeInsets.all(8),
              child: Column(
                children: employe.map((singleEmployeeData){
                      return Container(
                          child: Card(
                            child:ListTile( 
                              title: Text(singleEmployeeData.empName),
                              subtitle: Text(singleEmployeeData.phoneNumber + "\n" + singleEmployeeData.country),
                             
                             ),
                          ),
                          
                      );
                  }).toList(),
                ),
            ),
          ) 
        
      );
  }
}

class EmployeeData{
   String empid, empName, phoneNumber, country;
   EmployeeData({required this.empid, required this.empName, required this.phoneNumber, required this.country});
}

import 'package:flutter/material.dart';

void main() {

runApp(

MaterialApp(

home: MyApp(),

)

);

}

class MyApp extends StatefulWidget{

@override

_MyAppState createState() => _MyAppState();

}

class _MyAppState extends State<MyApp> {

List<EmployeeData> employe= [];

@override

void initState() {

employe.add(EmployeeData(empid:"108-01", empName:"Aman Bhatt", phoneNumber:"1234567890", country:"USA"));

employe.add(EmployeeData(empid:"108-02", empName:"Riya", phoneNumber:"0987654321", country:"India"));

employe.add(EmployeeData(empid:"108-03", empName:"Karan", phoneNumber:"7869805432", country:"India"));

employe.add(EmployeeData(empid:"108-04", empName:"Rihana", phoneNumber:"8976543210", country:"China"));

super.initState();

}

@override

Widget build(BuildContext context) {

return Scaffold(

appBar: AppBar(

title:Text("Employee List"),

backgroundColor: Colors.green,

body: SingleChildScrollView(

child: Container(

padding: EdgeInsets.all(8),

child: Column(

children: employe.map((singleEmployeeData){

return Container(

child: Card(

child:ListTile(

title: Text(singleEmployeeData.empName),

subtitle: Text(singleEmployeeData.phoneNumber + "\n" + singleEmployeeData.country),

);

}).toList(),

)

);

}

class EmployeeData{

String empid, empName, phoneNumber, country;

EmployeeData({required this.empid, required this.empName, required this.phoneNumber, required this.country});

}

Now, Run your App and see the list

Step 3:- Secondly, Add the delete button where you want, I am taking the delete button on the right side. Now I am adding an elevated button under the list view. you may add any button.

 trailing: ElevatedButton( 
                                  style: ElevatedButton.styleFrom(
                                    primary: Colors.black
                                  ),
                                  child: Icon(Icons.delete_forever_sharp),
                                  onPressed: (){
                                    //delete action for this button
                                      employe.removeWhere((element){
                                            return element.empid == singleEmployeeData.empid;
                                      }); //go through the loop and match content to delete from list
                                      setState(() {
                                        //refresh UI after deleting element from list
                                      });   
                                  },
                                ),

trailing: ElevatedButton(

style: ElevatedButton.styleFrom(

primary: Colors.black

child: Icon(Icons.delete_forever_sharp),

onPressed: (){

//delete action for this button

employe.removeWhere((element){

return element.empid == singleEmployeeData.empid;

}); //go through the loop and match content to delete from list

setState(() {

//refresh UI after deleting element from list

});

Run the project and see the output

Now, implement it’s functionality

 child: Card(
                            child:ListTile( 
                              title: Text(singleEmployeeData.empName),
                              subtitle: Text(singleEmployeeData.phoneNumber + "\n" + singleEmployeeData.country),
                             trailing: ElevatedButton( 
                                  style: ElevatedButton.styleFrom(
                                    primary: Colors.black
                                  ),
                                  child: Icon(Icons.delete_forever_sharp),
                                  onPressed: (){
                                    //delete action for this button
                                      employe.removeWhere((element){
                                            return element.empid == singleEmployeeData.empid;
                                      }); //go through the loop and match content to delete from list
                                      setState(() {
                                        //refresh UI after deleting element from list
                                      });   
                                  },
                                ),
 
                             ),
                          ),

child: Card(

child:ListTile(

title: Text(singleEmployeeData.empName),

subtitle: Text(singleEmployeeData.phoneNumber + "\n" + singleEmployeeData.country),

trailing: ElevatedButton(

style: ElevatedButton.styleFrom(

primary: Colors.black

child: Icon(Icons.delete_forever_sharp),

onPressed: (){

//delete action for this button

employe.removeWhere((element){

return element.empid == singleEmployeeData.empid;

}); //go through the loop and match content to delete from list

setState(() {

//refresh UI after deleting element from list

});

Now, Run the project and see the output
