builder property

Widget Function(BuildContext, List<ContributorStatistics>) builder
final

builder is where you return the code if the contributors list is not empty. This method is returned inside a StreamBuilder which checks if the list is empty or null before running builder, so no need to double check if it is empty. Though it wouldn't hurt to do it. Look at the source code for more info how this works behind the scenes.

Implementation

final Widget Function(BuildContext, List<ContributorStatistics>) builder;
