paginated_data_table_2
library
Classes
-
AsyncDataTableSource
-
Implement this class and use it in conjunction with AsyncPaginatedDataTable2
to allow asynchronous data fetching.
Please overide AsyncDataTableSource.getRows and DataTableSource.selectedRowCount
to make it legible as a data source.
-
AsyncPaginatedDataTable2
-
Asynchronous version of PaginatedDataTable2 which relies on data source
returning data rows wrappd in Future. Provides a straightworward way
of integrating data table with remote back-end and is loaded with
convenienece features such as error handling, reloading etc.

-
DataColumn2
-
Extension of stock DataColumn, adds the capability to set relative column
size via size property
-
DataRow2
-
Extension of standard DataRow, adds row level tap events. Also there're
onSecondaryTap and onSecondaryTapDown which are not available in DataCells and
which can be useful in Desktop settings when a reaction to the right click is required.
-
DataTable2
-
In-place replacement of standard DataTable widget, mimics it API.
Has the header row always fixed and core of the table (with data rows)
scrollable and stretching to max width/height of it's container.
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.
-
PaginatedDataTable2
-
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.

PaginatedDataTable2State
-
Holds the state of a PaginatedDataTable2.
-
PaginatorController
-
Allows to externally control PaginatedDataTable2 state
and trigger actions such as changing page number or size. Instatiate an object,
keep it somewhere (e.g. parent widgets state or static field/top level variable),
pass it to PaginatedDataTable2.controller via constructor and you're ready to go.
Please note that there're a few properties that allow to fetch internal state
value's (such as rows per page), those values can't be fetched until the
controller is attached - this happens during the first call to the build()
method of PaginatedDataTable2.
The controller extends ChangeNotifier in order to let consumers know
if there're changes to PaginatedDataTable2 state. E.g. you can hide
standard paginator of PaginatedDataTable2 and simplement your own
paginator as a StatefullWidget, subsribe to controller in order to update
the paginator.

SyncedScrollControllers
-
Creates pairs of scroll controllers which can be provided to scrollables and ensure that
offset change in one scrollable scroll the second one (and vice a versa)
There's a bug (or feature) on iOS with bouncing scroll (when it goes out of range)
when scrollable get out of sync while in this bouncing position
-
Enums
-
ColumnSize
-
Relative size of a column determines the share of total table width allocated
to each individual column. When determining column widths ratios between S, M and L
columns are kept (i.e. Large columns are set to 1.2x width of Medium ones)
-
PageSyncApproach
-
Should data source return less rows that ca
-
SelectionState
-
AsyncDataTableSource states:
none -> toggle/selectAllOnPage -> include
include -> toggle/deselectAllOnPage -> no
include -> selectAll -> exclude
none -> selectAll -> exclude
exclude -> deselectAll -> none
exclude -> toggle/selectAllOnPage/deselectAllOnPage -> exclude
