Issue
I want to import data into firebase database from a CSV file in flutter. So I pick .CSV file from device using file picker. Now how can I read data from that file?
Solution
At first import file_picker and CSV package from dart packages. Than define the method pickFile() as i have given below. it will pick the file from device storage and after selection it will print data. pickFile() funtion shoulb be called to get result.
import 'package:file_picker/file_picker.dart';
import 'package:csv/csv.dart';
import 'dart:convert' show utf8;
pickFile() async {
FilePickerResult result = await FilePicker.platform.pickFiles();
if (result != null) {
PlatformFile file = result.files.first;
final input = new File(file.path).openRead();
final fields = await input
.transform(utf8.decoder)
.transform(new CsvToListConverter())
.toList();
print(fields);
}
}
