hr method

List<int> hr({
  1. String ch = '-',
  2. int? len,
  3. int linesAfter = 0,
})

Print horizontal full width separator If len is null, then it will be defined according to the paper width

Implementation

List<int> hr({String ch = '-', int? len, int linesAfter = 0}) {
  List<int> bytes = [];
  int n = len ?? _maxCharsPerLine ?? _getMaxCharsPerLine(_styles.fontType);
  String ch1 = ch.length == 1 ? ch : ch[0];
  bytes += text(List.filled(n, ch1).join(), linesAfter: linesAfter);
  return bytes;
}
