final fp = FlexPrint();
  fp.horizontalLine(doubleLine: true);

  fp.write('Amount Due', flex: 2, alignment: Alignment.end);
  fp.write('Invoice Details', flex: 3);
  fp.write('Status', flex: 2, alignment: Alignment.center);
  fp.write('\n');
  fp.horizontalLine(doubleLine: true);
  customers.forEach((row) {
    fp.write(row.name, flex: 3);
    fp.write(row.amountDue.toString(), flex: 2, alignment: Alignment.end);
    fp.write(row.invoiceDetail, flex: 3);
    fp.write(row.status, flex: 2, alignment: Alignment.center);
    fp.write('\n');
  });
  fp.horizontalLine(char: '_');

Line Width, Padding, Overflow

The default line width is 80 characters long, padding is 1 character, Overflow is truncated. Any or all of these can be set through the construtor.

Adding Columns

Any number of columns may be added through the write() method. The first column with a newline ('\n') character outputs that row and subsequent writes add to the next row.

Flex

Each column has a default flex factor of 1. You may specify any flex number.

Alignment

You may specify that a column be justified left - Alignment.start, center - Alignment.Center, right Alignment,end

Overflow

If you set overflow to Overflow,wrap, FlexPrint will wrap text within the column, otherwise the overflow text is truncated to the width of column.
