ExpansionPanelList constructor

const ExpansionPanelList({
  1. Key? key,
  2. List<ExpansionPanel> children = const <ExpansionPanel>[],
  3. ExpansionPanelCallback? expansionCallback,
  4. Duration animationDuration = kThemeAnimationDuration,
  5. EdgeInsets expandedHeaderPadding = _kPanelHeaderExpandedDefaultPadding,
  6. Color? dividerColor,
  7. double elevation = 2,
  8. Color? expandIconColor,
  9. double materialGapSize = 16.0,
})

Implementation

const ExpansionPanelList({
  super.key,
  this.children = const <ExpansionPanel>[],

  this.expandedHeaderPadding = _kPanelHeaderExpandedDefaultPadding,
  this.dividerColor,
  this.elevation = 2,
  this.expandIconColor,
  this.materialGapSize = 16.0,
}) : _allowOnlyOnePanelOpen = false,
     initialOpenPanelValue = null;
