# data_tables

- Full Screen Paginated Data Tables for Tablets/Desktops
- Mobile ListView with Action Buttons for Sorting and Selecting All
- Supports Dark Mode
- From Json

Online Demo: https://rodydavis.github.io/data_tables/

## Getting Started

- You can optionally build the listview for mobile with a builder, by default it creates a ExpansionTile with the remaining columns as children
- The tablet breakpoint can also be set.

  `bool showMobileListView;` - When set to false it will always show a data table

  `int sortColumnIndex;` - Current Sorted Column

  `bool sortAscending;` - Sort Order

  `ValueChanged<bool> onSelectAll;` - Called for Selecting and Deselecting All

  `ValueChanged<int> onRowsPerPageChanged;` - Called when rows change on data table or last row reached on mobile.

  `int rowsPerPage;` - Default Rows per page

  `Widget header;` - Widget header for Desktop and Tablet Data Table

  `List<DataColumn> columns;` - List of Columns (Must match length of DataCells in DataSource)

  `IndexedWidgetBuilder mobileItemBuilder;` - Optional Item builder for the list view for Mobile

  `Size tabletBreakpoint;` - Tablet breakpoint for the screen width and height

  `List<Widget> actions, selectedActions;` - Actions that show when items are selected or not

  `RefreshCallback onRefresh;` - If not null the list view will be wrapped in a RefreshIndicator
