flex_grid

The FlexGrid control provides a powerful and quickly way to display data in a tabular format. It is including that frozened column/row,loading more, high performance and better experience in TabBarView/PageView.

source

[FlexGrid.source] is form loading_more_list, LoadingMoreBase is data collection for loading more. override loadData method to load your data. set hasMore to false when it has no more data.

class FlexGridSource extends LoadingMoreBase<GridRow> {
  int _pageIndex = 1;

  void _load() {
    for (int i = 0; i < 15; i++) {
      add(GridRow(name: 'index:$_pageIndex-$i'));
    }
  }

  @override
  bool get hasMore => _pageIndex < 4;

  @override
  Future<bool> loadData([bool isloadMoreAction = false]) async {
    await Future<void>.delayed(const Duration(seconds: 2));
    _load();
    _pageIndex++;
    return true;
  }

  @override
  Future<bool> refresh([bool notifyStateChanged = false]) async {
    _pageIndex = 1;
    return super.refresh(notifyStateChanged);
  }
}
Dart

rowWrapper

decorate row widget in this call back.

    FlexGrid(
      rowWrapper: (
        BuildContext context,
        T data,
        int row,
        Widget child,
      ) {
        return Column(
          children: <Widget>[
            child,
            const Divider(),
          ],
        );
      },
    );
Dart

headersBuilder

you can add anyother headers in this call back.

    FlexGrid(
      headersBuilder: (BuildContext b, Widget header) {
        return <Widget>[
          header,
          SliverToBoxAdapter(
            child: PullToRefreshContainer(
                (PullToRefreshScrollNotificationInfo info) {
              return PullToRefreshHeader(
                info,
                source.lastRefreshTime,
              );
            }),
          ),
        ];
      },
    );
