scrollIntoView method Null safety

void scrollIntoView(
  1. [ScrollAlignment? alignment]
)

Scrolls this element into view.

Only one of of the alignment options may be specified at a time.

If no options are specified then this will attempt to scroll the minimum amount needed to bring the element into view.

Note that alignCenter is currently only supported on WebKit platforms. If alignCenter is specified but not supported then this will fall back to alignTop.
