Pass the csvConfiguration, only needed if the CSV has titles and the separator is not a ','; CsvConfiguration accept 3 properties:

Separator separator with default set to Separator.coma (',')
bool hasTitle with default set to true
List<String> titles only needed if hasTitle is set to False but you want to get each lines returned as a Map<String, dynamic> with the title of the column has the key;

CsvButton can return two types of callBacks:

onJsonReceived which return each line as Map<String, dynamic> and onStringReceived which return each line as String so you can parse it yourself;

CsvButton(
  onJsonReceived: (Map<String, dynamic> data) => print("$data"),
  child: Text('pick a csv')
  );
