insert method

void insert(
  1. dynamic currentRow,
  2. dynamic item
)

表单插入，可以是单个 row，也可以使一组 rows

Implementation

void insert(currentRow, item) {
  if (item is List<TFormRow>) {
    rows.insertAll(rows.indexOf(currentRow) + 1,
        item.map((e) => e..animation = true).toList());
  } else if (item is TFormRow) {
    rows.insert(rows.indexOf(currentRow), item..animation = true);
  }
  reload();
}
