Parsing csv data - Flutter-CodePudding

I'm receiving data from the csv file as

SERVICE_ID‡WEIGHT_ID‡DISTANCE_ID‡BASE_PRICE‡IDENTIFIER
PARCEL‡W0‡‡0.00‡N
PARCEL‡W1‡‡19.00‡N

Upon extracting this file with the help of CsvToListConverter() I was able to print the data as

[SERVICE_ID, WEIGHT_ID, DISTANCE_ID, BASE_PRICE, IDENTIFIER
PARCEL, W0, , 0.00, N
PARCEL, W1, , 19.00, N]

So i just removed the first row by using the range property result.removeRange(0, 4); and printed the result as

[PARCEL, W0, , 0.00, N
PARCEL, W1, , 19.00, N]

Actually the 4 index is being taken both N & Parcel together If i print result[4], I'm getting as NParcel where in it should be only N

This is the model representation

class mode {
 final String type;
 final String code;
 final String isSent;
 final String price;
 final String delivered;

mode(this.type, this.code, this.isSent, this.price, this.delivered)
}

How to extract the data? Note There is no Comma symbol after N nor any new line \n code

CSV Data can extract like this,

class RowData
{
 final String Column1;
 final String Column2;

 RowData(this.Column1, this.Column2)
}

List <RowData> tableData = [];

int colCount = 2;
List rawDataList = ["H1", "H2", "R1C1", "R1C2", "R2C1", "R2C2"];

for(int i = colCount - 1; i < rawDataList.length / colCount; i  = colCount)
{
  tableData.add(rawDataList[i], rawDataList[i   1]);
}

you can create a list of mode like this:

  List list =
  ['PARCEL', 'W0','' , 0.00, 'N'
  'PARCEL', 'W1', '', 19.00, 'N'];
  List <mode> modeList = [];
  for (int i=0;i<list.length/5;i  ){
  modeList.add(mode(list[i],list[i 1],list[i 2],list[i 3],list[i 4]));
  }
