Real time data type issue in flutter

If I receive real-time data, sometimes the type is List , and sometimes the type is Map<String, dynamic>, and on each type, I want to perform different operations; how can I differentiate them?

you can use this function , it return 0--> when given argument is List,1 --> when given argument is Map, 2--> when given argument is no List or Map

int  isListOrMap(var d){
  if(d is List){
    return 0;
  }
  if(d is Map){
    return 1;
  }
  return 2;
}
