getOutgoingEdgesByString method
Gets all neighboring edges of a source
that gets searched by string in graph
Implementation
@override
List<UndirectedEdge> getOutgoingEdgesByString(String source) {
List<UndirectedEdge> tmp = [];
tmp.addAll(graph[getVertexByString(source)]! as List<UndirectedEdge>);
return tmp;
}
