PanelContent constructor Null safety

const PanelContent(
  1. {PanelHeaderWidget headerWidget = const PanelHeaderWidget(),
  2. PanelFooterWidget footerWidget = const PanelFooterWidget(),
  3. required List<Widget> panelContent,
  4. Widget? bodyContent,
  5. PanelCollapsedWidget collapsedWidget = const PanelCollapsedWidget()}
)

Implementation

const PanelContent({
  this.headerWidget = const PanelHeaderWidget(),
  this.footerWidget = const PanelFooterWidget(),
  required this.panelContent,
  this.bodyContent,
  this.collapsedWidget = const PanelCollapsedWidget(),
}) : assert(panelContent != null);
