to csv

You can create and download a CSV/Excel file with much less code. Do not forget to like the package if this helped you...
How to use it? #

Firstly, add to_csv as a dependency in your pubspec.yaml file.
And import this as in your dart file:

import 'package:to_csv/to_csv.dart' as exportCSV;
copied to clipboard

In your onPressed/onTap function (or wherever you like), create a list of Strings that will be the Header of your table or excel file.

List<String> header = [];
header.add('No.');
header.add('User Name');
header.add('Mobile');
header.add('ID Number');
copied to clipboard

Also create a two lists which contains your list of rows as List

List<List<String>> listOfLists = []; //Outter List which contains the data List
List<String> data1 = ['1','Bilal Saeed','1374934','912839812']; //Inner list which contains Data i.e Row
List<String> data2 = ['2','Ahmar','21341234','192834821']; //Inner list which contains Data i.e Row
copied to clipboard
Note: Length of elements present in Rows should be equal to the length of header list length

Now add your data variables in listOfVisitor which is List of List of Strings actually.

listOfLists.add(data1);
listOfLists.add(data2);
copied to clipboard

Finally pass header and listOfVisitors to the package function like this:

exportCSV.myCSV(header, listOfLists);
copied to clipboard
And your csvFile will be downloaded in no minutes.
Open it on excel or in any other app and Enjoy!
Your final output will be: #

Configuration FOR IOS: #
Go to your project folder, ios/Runner/info.plist and Add these keys:
<key>LSSupportsOpeningDocumentsInPlace</key>
<true/>
<key>UIFileSharingEnabled</key>
<true/>
copied to clipboard

Or Configure in XCode: #
Open Your Project in XCode (Open XCode -> Open a project or file -> Your_Project_Folder/ios/Runner.xcworkspace) Open info.plist Add these rows:
Application supports iTunes file sharing (Boolean -> Yes)
Supports opening documents in place (Boolean -> Yes)

Recent Changes in New Version 4.0.0 #
1. *) Added property emptyRowsConfig to add multiple empty rows on multiple places,
*) Added property removeDuplicates to remove duplicate values in data,
*) Added noDuplicatedCheckAfterSpecificRow to stopChecking duplicate rows after a certain row
*) Data can be transposed now from a specific row
Take a look at this code:
```
dart await myCSV(header, listOfLists,setHeadersInFirstRow:false,includeNoRow: true,sharing: false, removeDuplicates: true, showDuplicateValue:true,noDuplicatedCheckAfterSpecificRow: 3 );```
copied to clipboard
2. Column headers can now be switched as the first element of each row.
When setHeadersInFirstRow is set to false like the following code:
await myCSV(header, listOfLists,setHeadersInFirstRow:false,includeNoRow: true, sharing: false);
copied to clipboard
Output would be:

But when setHeadersInFirstRow is set to true, OUTPUT would be:

You can also set dart includeNoRow: false to remove No. row/column
3. You can also design your csv like this
by using this code:
await myCSV(header, listOfLists,
sharing: false,
setHeadersInFirstRow: false,
fileName: "myProjectCSV-",
removeDuplicates: true,
showDuplicateValue: false,
emptyRowsConfig: {11: 2},
noDuplicatedCheckAfterSpecificRow: 10,
transposeAfterRow: 11);
copied to clipboard
4. Compatible with Dart 3 now. Compiled with Flutter 3.22.2 ##3.0.0 & resolved all flutter analyze issues
