Implementation
@override
void clear() {
for (var y = 0; y < bounds.height; y++) {
for (var x = 0; x < bounds.width; x++) {
final cell = parent.getCell(bounds.x + x, bounds.y + y);
if (cell != null) {
if (cell.char != ' ' || cell.style != Style.transparent) {
cell.char = ' ';
cell.style = Style.transparent;
}
}
}
}
}
