PaginatedDataTable2 class

In-place replacement of standard PaginatedDataTable widget, mimics it API. Has the header row and paginatior always fixed to top and bottom (correspondingly). Core of the table (with data rows) is scrollable and stretching to max width/height of it's container. You can set minimal width of the table via minWidth property and Flex behavior of table core via fit property. By using DataColumn2 instead of DataColumn it is possible to control relative column sizes (setting them to S, M and L). DataRow2 provides row-level tap event handlers. See also:

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.
final
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
final
availableRowsPerPage → List<int>
The options to offer for the rowsPerPage.
final
border → TableBorder?
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
final
checkboxAlignment → Alignment
Alignment of the checkbox if it is displayed Defaults to the Alignment.center
final
checkboxHorizontalMargin → double?
Horizontal margin around the checkbox, if it is displayed.
final
columns → List<DataColumn>
The configuration and labels for the columns in the table.
final
columnSpacing → double
The horizontal margin between the contents of each data column.
final
controller → PaginatorController?
Used to comntrol widget's state externally and trigger actions. See PaginatorController
final
datarowCheckboxTheme → CheckboxThemeData?
Overrides theme of the checkbox that is displayed in the checkbox column in each data row (should checkboxes be enabled)
final
dataRowHeight → double
The height of each row (excluding the row that contains column headings).
final
dataTextStyle → TextStyle?
The text style for data rows.
final
dividerThickness → double?
The divider thickness between rows.
final
dragStartBehavior → DragStartBehavior
Determines the way that drag start behavior is handled.
final
empty → Widget?
Placeholder widget which is displayed whenever the data rows are empty. The widget will be displayed below column
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)
final
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
final
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
final
fixedLeftColumns → int
Number of sticky columns fixed at the left side of the table. Check box column (if enabled) is also counted
final
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)
final
hashCode → int
The hash code for this object.
no setterinherited
The table card's optional header.
final
headingCheckboxTheme → CheckboxThemeData?
The theme for the heading row checkboxes.
final
headingRowColor → MaterialStateProperty<Color?>?
The background color for the heading row.
final
headingRowDecoration → BoxDecoration?
If set this field will override the current BoxDecoration. It takes precedence over headerRowColor when both are provided.
final
headingRowHeight → double
The height of the heading row.
final
headingTextStyle → TextStyle?
The text style for the heading row.
final
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
final
horizontalMargin → double
The horizontal margin between the edges of the table and the content in the first and last cells of each row.
final
horizontalScrollController → ScrollController?
Exposes scroll controller of the SingleChildScrollView that makes data rows horizontally scrollable
final
initialFirstRowIndex → int?
The index of the first row to display when the widget is first created.

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)
final
onPageChanged → ValueChanged<int>?
Invoked when the user switches to another page.
final
onRowsPerPageChanged → ValueChanged<int?>?
