constraints property
final
Constrains the size of the Tooltip's message.
If null, then the TooltipThemeData.constraints of the ambient ThemeData.tooltipTheme
will be used. If that is also null, then a default value will be picked based on the current
platform. For desktop platforms, the default value is BoxConstraints(minHeight: 24.0),
while for mobile platforms the default value is BoxConstraints(minHeight: 32.0).
Implementation
final BoxConstraints? constraints;
