rowTooltipTheme property
Presentation and behaviour for the card built by rowTooltipBuilder: when it appears, whether the cursor may enter it, where it sits relative to the pointer, how it animates, and whether the tooltip draws a surface around it.
Null means RowTooltipTheme's defaults — shown immediately on hover, interactive, and drawing no surface of its own.
Implementation
final RowTooltipTheme? rowTooltipTheme;
