Properties

backgroundColor → Color?
The color to display behind the sublist when expanded.
final
border → BoxBorder?
Use Border objects to describe borders that do not depend on the reading direction.
final
borderRadius → BorderRadius?
If non-null, the corners of this box are rounded by this BorderRadius.
final
boxShadow → List<BoxShadow>?
A list of shadows cast by this box behind the box. The shadow follows the shape of the box. See also: kElevationToShadow, for some predefined shadows used in Material Design. PhysicalModel, a widget for showing shadows.
final
children → List<Widget>?
The widgets that are displayed when the tile expands.
final
childrenPadding → EdgeInsetsGeometry?
Specifies padding for children.
final
clipBehavior → Clip?
The clip behavior when Container.decoration is not null. Defaults to Clip.none. Must be Clip.none if decoration is null. If a clip is to be applied, the Decoration.getClipPath method for the provided decoration must return a clip path. (This is not supported by all decorations; the default implementation of that method throws an UnsupportedError.)
final
collapsedBackgroundColor → Color?
When not null, defines the background color of tile when the sublist is collapsed.
final
collapsedBorderColor → Color?
The color to display border box when collapsed.
final
collapsedIconColor → Color?
The icon color of tile's expansion arrow icon when the sublist is collapsed.
final
collapsedTextColor → Color?
The color of the tile's titles when the sublist is collapsed.
final
controlAffinity → ListTileControlAffinity?
Typically used to force the expansion arrow icon to the tile's leading or trailing edge.
final
controller → ExpansionGroupController?
final
decoration → Decoration?
The decoration to paint behind the child. Use the color property to specify a simple solid color. The child is not clipped to the decoration. To clip a child to the shape of a particular ShapeDecoration, consider using a ClipPath widget.
final
expandedAlignment → Alignment?
Specifies the alignment of children, which are arranged in a column when the tile is expanded.
final
expandedCrossAxisAlignment → CrossAxisAlignment?
Specifies the alignment of each child within children when the tile is expanded.
final
expansionKey → GlobalKey<ExpansionTileCoreState>?
Specifies if the item is expanded or not.
final
expendedBorderColor → Color?
The color to display border box when expanded.
final
hashCode → int
The hash code for this object.
no setterinherited
iconColor → Color?
The icon color of tile's expansion arrow icon when the sublist is expanded.
final
index → int?
final
initiallyExpanded → bool
Specifies if the list tile is initially expanded (true) or collapsed (false, the default).
final
isDefaultVerticalPadding → bool?
Remove completely default vertical title padding
final
isEnableExpanded → bool?
The widget can expand or NOT. It helps when you want to prohibit expansion until the API requests success. More detail: https://github.com/congthanhng/Expansion-Tile-Group/issues/22
final
isHasBottomBorder → bool?
final
isHasLeftBorder → bool?
final
isHasRightBorder → bool?
final
isHasTopBorder → bool?
final
isHasTrailing → bool?
Permanently hide trailing included default icon
final
isHideSubtitleOnExpanded → bool?
Hide subtitle on expanded view
final
isOnlyTrailingDoToggle → bool?
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
leading → Widget?
A widget to display before the title.
final
maintainState → bool
Specifies whether the state of the children is maintained when the tile expands and collapses.
final
onExpansionChanged → ValueChanged<bool>?
Called when the tile expands or collapses.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
subtitle → Widget?
Additional content displayed below the title.
final
textColor → Color?
The color of the tile's titles when the sublist is expanded.
final
themeData → ThemeData?
Specifies the color and typography values for descendant widgets.
final
tilePadding → EdgeInsetsGeometry?
Specifies padding for the ListTile.
final
title → Widget
The primary content of the list item.
final
trailing → Widget?
A widget to display after the title.
final
trailingIcon → Widget?
By default, ExpansionTile has default trailing icon with rotate animation whenever it is expanded/collapsed. This property used to override the default trailing icon.
final
