Properties

actions List<Widget>?
Icon buttons to show at the top end side of the table. The header must not be null to show the actions.
finalinherited
autoRowsToHeight bool
If true rows per page is set to fill available height so that no scroll bar is ever displayed. rowsPerPage is ignore when this field is set to true
finalinherited
availableRowsPerPage List<int>
The options to offer for the rowsPerPage.
finalinherited

Set vertical and horizontal borders between cells, as well as outside borders around table. NOTE: setting this field will disable standard horizontal dividers which are controlled by themes and dividerThickness property
finalinherited
checkboxAlignment Alignment
Alignment of the checkbox if it is displayed Defaults to the Alignment.center

finalinherited
columns List<DataColumn>
The configuration and labels for the columns in the table.
finalinherited
columnSpacing double
The horizontal margin between the contents of each data column.
finalinherited
controller PaginatorController?
Used to comntrol widget's state externally and trigger actions. See PaginatorController
finalinherited
datarowCheckboxTheme CheckboxThemeData?
Overrides theme of the checkbox that is displayed in the checkbox column in each data row (should checkboxes be enabled)
finalinherited
dataRowHeight double
The height of each row (excluding the row that contains column headings).
finalinherited

finalinherited
dividerThickness double?
The divider thickness between rows.
finalinherited
dragStartBehavior DragStartBehavior
Determines the way that drag start behavior is handled.
finalinherited
empty Widget?
Placeholder widget which is displayed whenever the data rows are empty. The widget will be displayed below column
finalinherited
errorBuilder Widget Function(Object? error)?
The function allows displaying custom widget on top of table should an error happen. E.g. data source faild to load data
final
fit FlexFit
Data rows are wrapped in Flexible widget, this property sets its' fit property. When ther're few rows it determines if the core of the table must grow and fill the contrainer (FlexFit.tight - useful if you want the paginator to stick to the bottom when there're few rows) or of you want to have the table to take minimal space and do not have bottom pager stick to the bottom (FlexFit.loose)
finalinherited
fixedColumnsColor Color?
Backgound color of the sticky columns fixed via fixedLeftColumns. Note: unlike data rows which can change their colors depending on material state (e.g. selected, hovered) this color is static and doesn't repond to state change Note: to change background color of fixed data rows use PaginatedDataTable2.headingRowColor and individual row colors of data rows provided via rows
finalinherited
fixedCornerColor Color?
Backgound color of the top left corner which is fixed whenere both fixedTopRows and fixedLeftColumns are greater than 0 Note: unlike data rows which can change their colors depending on material state (e.g. selected, hovered) this color is static and doesn't repond to state change Note: to change background color of fixed data rows use PaginatedDataTable2.headingRowColor and individual row colors of data rows provided via rows
finalinherited
fixedLeftColumns int
Number of sticky columns fixed at the left side of the table. Check box column (if enabled) is also counted
finalinherited
fixedTopRows int
The number of sticky rows fixed at the top of the table. The heading row is counted/included. By defult the value is 1 which means header row is fixed. Set to 0 in order to unstick the header, set to >1 in order to fix data rows (i.e. in order to fix both header and the first data row use value of 2)
finalinherited
hashCode int
The hash code for this object.

The theme for the heading row checkboxes.
finalinherited
headingRowColor MaterialStateProperty<Color?>?
The background color for the heading row.
finalinherited

finalinherited
headingRowHeight double
The height of the heading row.
finalinherited
headingTextStyle TextStyle?
The text style for the heading row.
finalinherited
hidePaginator bool
Hides the paginator at the bottom. Can be useful in case you decide create your own paginator and control the widget via PaginatedDataTable2.controller
finalinherited
horizontalMargin double
The horizontal margin between the edges of the table and the content in the first and last cells of each row.
finalinherited
horizontalScrollController ScrollController?
Exposes scroll controller of the SingleChildScrollView that makes data rows horizontally scrollable
finalinherited
initialFirstRowIndex int?
The index of the first row to display when the widget is first created.
finalinherited
isHorizontalScrollBarVisible bool?
Determines whether the horizontal scroll bar is visible, for iOS takes value from scrollbarTheme when null
finalinherited
isLoadingBarShown bool?
Determines whether the loading bar is visible
finalinherited
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited

Determines ratio of Large column's width to Medium column's width. I.e. 2.0 means that Large column is twice wider than Medium column.
finalinherited
loading Widget?
Widget that is goin to be displayed while loading is in progress If no widget is specified the following defaul widget will be disoplayed:
final
minWidth double?
If set, the table will stop shrinking below the threshold and provide horizontal scrolling. Useful for the cases with narrow screens (e.g. portrait phone orientation) and lots of columns (that get messed with little space)
finalinherited
onPageChanged ValueChanged<int>?
Invoked when the user switches to another page.
finalinherited
onRowsPerPageChanged ValueChanged<int?>?
