getBaseDetails method
Construct a base details element for a given datum.
This is intended to be overridden by child classes that need to add customized rendering properties.
Implementation
@override
_BarTargetLineRendererElement getBaseDetails(dynamic datum, int index) {
final localConfig = config as BarTargetLineRendererConfig<D>;
return _BarTargetLineRendererElement(
roundEndCaps: localConfig.roundEndCaps);
}
