FlatListItem class

A FlatListItem is typically added to a ListView to display textual information. FlatListItem is divided into three columns, wherein, the first one on the left displays an icon, second and the third column each have 2 rows, wherein, the first row is typically used to display the headings to represent the data that is displayed in the second row. The container that holds all these columns and items is called as a 'holder' in a FlatListItem, whose dimensions are calculated automatically based on the dimensions of the user device screen and the ScalePreset chosen by the user. Also, based on the ScalePreset chosen, all the items of the holder are scaled accordingly. It is important to know that if a FlatListItem is added to a ListView, the indexInList field is typically used to hold its index in the ListView to which it is added, so that it becomes possible to query a FlatListItem when added to ListView to get its position within the ListView.

Methods

build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget. [...]
computedMaxLinesToDisplay() int
Returns the maximum lines to display in the rightDataText row based on the ScalePreset chosen by the user. The smaller the ScalePreset chosen the lesser the number of lines displayed and vice-versa. When ScalePreset.minimal is selected '1' line is displayed, '2' lines in case of ScalePreset.small and ScalePreset.normal, '3' in case of ScalePreset.large and '8' in Portrait orientation and '5' in Landscape orientation for ScalePreset.gigantic.
createElement() → StatelessElement
Creates a StatelessElement to manage this widget's location in the tree. [...]
inherited
debugDescribeChildren() List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children. [...]
@protected, inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toDiagnosticsNode({String name, DiagnosticsTreeStyle style }) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep. [...]
inherited
toString({DiagnosticLevel minLevel: DiagnosticLevel.debug }) String
Returns a string representation of this object.
inherited
toStringDeep({String prefixLineOne: '', String prefixOtherLines, DiagnosticLevel minLevel: DiagnosticLevel.debug }) String
Returns a string representation of this node and its descendants. [...]
inherited
toStringShallow({String joiner: ', ', DiagnosticLevel minLevel: DiagnosticLevel.debug }) String
