Flutter: Load and display content from CSV files

Last updated on January 25, 2021 A Goodman Loading... 9 comments

CSV stands for Comma-Separated Values, is a file type widely used to store tabular data (numbers and text) in the plain text where each line will have the same number of fields. In this article, we will explore how to read content from a CSV file in Flutter and display that content on the screen.

Below is the CSV file used in the following example. Just download it before diving into the code:


The content inside this file is simple as below:

1,John Doe,40
4,Joe Biden,80
5,Ryo Hanamura,35

The Complete Example


This example has a floating button. When this button is pressed, the data from the CSV file will be loaded and displayed in a ListView:

The steps

1. Copy the CSV file to the assets folder (create one if it doesn’t exist) in the root directory of your project. Don’t forget to declare this assets folder in the pubspec.yaml:

# The following section is specific to Flutter.
    - assets/

2. Install the csv package by adding the following to pubspec.yaml:

  csv: ^4.1.0

Then run:

flutter pub get

3. Add the following to your main.dart:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart' show rootBundle;

import 'package:csv/csv.dart';

void main() {

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Kindacode.com',
      home: HomePage(),

class HomePage extends StatefulWidget {
  _HomePageState createState() => _HomePageState();

class _HomePageState extends State<HomePage> {
  List<List<dynamic>> _data = [];

  // This function is triggered when the floating button is pressed
  void _loadCSV() async {
    final _rawData = await rootBundle.loadString("assets/kindacode.csv");
    List<List<dynamic>> _listData = CsvToListConverter().convert(_rawData);
    setState(() {
      _data = _listData;

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Kindacode.com"),
      body: ListView.builder(
        itemCount: _data.length,
        itemBuilder: (_, index) {
          return Card(
            margin: const EdgeInsets.all(3),
            color: index == 0 ? Colors.amber : Colors.white,
            child: ListTile(
              leading: Text(_data[index][0].toString()),
              title: Text(_data[index][1]),
              trailing: Text(_data[index][2].toString()),
          FloatingActionButton(child: Icon(Icons.add), onPressed: _loadCSV),

Now run your app and you will see it works as the video above.

If you prefer to implement a Table instead of a ListView, check this guide: Working with Table in Flutter.

After getting listview from CSV document if I want to add search option, how should I approach for this code? That means I give a input if it matches with any item in the list (which we got from CSV), it shows that item from the list. Here, data comes… Read more »

instead of writing “void _loadCSV() async{ …” I have written only “_loadCSV() async{ …”. That means, I removed void from that line.And In body: I added FutureBuilder in the code attached in the image.

Now, CSV document doesn’t appear. Only circular indicator appears. What should I do?

What will be the code, if we directly show the list instead of clicking button with search option?
