goToRow method
Switch the page so that he given row is displayed at the top. I.e. it is possible to have pages start at arbitrary rows, not at the boundaries of pages as determined by page size.
Implementation
void goToRow(int rowIndex) {
_assertIfNotAttached();
// if (_state != null) {
// _state!.setState(() {
// _state!._firstRowIndex =
// math.max(math.min(_state!._rowCount - 1, rowIndex), 0);
// });
//}
_state?.pageTo(rowIndex, false);
}
