app show error but not crash

LoadStatus.completed not working in loadMoreBuilder

loadMoreBuilder: (BuildContext context, LoadStatus status) { if (status == LoadStatus.loading) { return Container( height: 40, alignment: Alignment.center, child: Row( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ SizedBox( child: CircularProgressIndicator(), width: 15, height: 15, ), Container( margin: EdgeInsets.fromLTRB(5, 0, 5, 0), ), Text('Loading...', style: TextStyle(fontSize: 12,fontWeight: FontWeight.w600)), ], ) ); } if (status == LoadStatus.completed) { return Container( height: 40, alignment: Alignment.center, child: Text('That is the end', style: TextStyle(fontSize: 12,fontWeight: FontWeight.w600)), ); } return null; },

For some reasons, set if (status == LoadStatus.completed) in loadMoreBuilder does not works, and the widget never shows unless you hot reload in IDE.

progress not coming.

Make messages editable

For internationalization purposes.. can you make the messages being passed through constructor ?

Multiple _buildLoadMore.

When RefreshIndicator is being used, in each update _buildLoadMore is being added to the end of the list.

I don't know if the problem is with this part of the code

widget.child.slivers.add(
      SliverSafeArea(
        top: false,
        left: false,
        right: false,
        sliver: SliverToBoxAdapter(
          child: _buildLoadMore(widget.status),
        ),
      ),
    );
