FillingBar constructor

FillingBar({ required int total, String desc = "", String space = ".", String fill = "█", bool time = false, bool percentage = false, double scale = 0.5, int? width, })

Arguments:

• total : Total number of steps
• desc : Simple text shown before the bar (optional)
• space : Character denoting empty space (default : '.')
• fill : Character denoting filled space (default : '█')
• time : Toggle timing mode (default : false)
• percentage : Toggle percentage display (default : false)
• scale : Scale of the bar relative to width (between: 0 and 1, default: 0.5, Irrelavant if width is specified)
• width : Width of the bar (If not specified, it will be automatically calculated using the terminal width and scale)

Implementation

FillingBar(
    {required int total,
    String desc = "",
    this.space = ".",
    this.fill = "█",
    this.time = false,
    this.percentage = false,
    this.scale = 0.5,
    this.width})
    : _desc = desc,
      _total = total {
  // Handles width of the bar, throws an error if it's not specified and the terminal width is not available
  try {
    max = width ?? ((stdout.terminalColumns - _desc.length) * scale).toInt();
  } on StdoutException {
    throw StdoutException(
        "Could not get terminal width, try specifying a width manually");
  }
  if (time) {
    _clock.start();
    scheduleMicrotask(autoRender);
  }
  _render();
}
