Modify to handle multiple roles assigned to the user.
final userRoles = ["admin", "nurse"];

final roleFeatureMap = {
"admin": ["F1", "F2", "F3", "F4", "F5", "F6"],
"nurse": ["F1", "F4", "F5"],
"pathologist": ["F1", "F6", "F7"]
};

May use Set<String> which automatically eliminates duplicates

final Set<String> userFeatures = {};

for (final role in userRoles) {
if (roleFeatureMap.containsKey(role)) {
userFeatures.addAll(roleFeatureMap[role]!);
}
}
