writeLinesCSV function

Future<void> writeLinesCSV(Array2d data, String fileName, { String delimiter = ';', Encoding encoding = utf8, FileMode mode = FileMode.write, })

Write a list of line in a TXT file data : a list where each line is a string that will be written in the file fileName : file name or path of the file baseDir : optional, base directory to the file, if not informed, get current script path. delimiter : optional, string used to separate values, by default is ";" encoding : optional, the encoding of the file, default is utf8 mode : optional, the mode how the program will write the file:
