routeMap property
Implementation
Map<String, Route> get routeMap => charts
.map(
(chart) => chart.routeMap,
) // Map each chart to its `routeMap` or an empty map
.fold<Map<String, Route>>({}, (acc, routeMap) {
acc.addAll(
routeMap,
); // Merge the current chart's routeMap into the accumulator
return acc; // Return the updated accumulator
});
