<｜begin▁of▁sentence｜>### Instruction:
Given an igraph `Graph` object, how can the string representation of a `Flow` object be obtained, where the `Flow` object results from computing the maximum flow from a source vertex to a target vertex within the graph?
### Response:
from igraph import Graph
import json
from igraph import Flow

# Create an example igraph
graph = Graph.Erdos_Renyi(n=10, m=20)

# Calculate the maximum flow between vertex 0 and vertex 5
max_flow = graph.maxflow(source=0, target=5)

# Get the string representation of the Flow object using __repr__
flow_repr = max_flow.__repr__()

# Print the representation
print(flow_repr)
