Dart - named parameters using a Map

Question

I would like to know if I can call a function with name parameters using a map e.g.

void main()
{
  Map a = {\'m\':\         


        

Answer 1

You can use Function.apply to do something similar :

main() {
  final a = new Map();
  a[const Symbol('m')] = 'done';
  Function.apply(slave, [], a);
}

You can also extract an helper method to simplify the code :

main() {
  final a = symbolizeKeys({'m':'done'});
  Function.apply(slave, [], a);
}

Map symbolizeKeys(Map map){
  final result = new Map();
  map.forEach((String k,v) { result[new Symbol(k)] = v; });
  return result;
}
