How to add dynamic value in Map in Dart?

I have a dynamic UI which maybe dropdown or textField!

I need to prepare map to send to backend. Below is map format that i need to prepare from the dynamic UI,

Map temp;

  temp = {
    "receiver": {
      "Bank": {"accounnt": '123'},
    }
  };
  if(temp['receiver']['school'] == null){
    temp['receiver']['school'] = '12';
  }

But where I am getting error when I am trying to add temp['receiver']['school'] = '12';. The error states that, type 'String' is not a subtype of type 'Map<String, String>' of 'value.'

I want to create a map in below format,

  "receiver": {
    "bank_account": {
      "swift_bic": "XXX",
      "account_number": "225225"
    },
    "reason_for_sending": "Family"
  }

Try This:

void main() {
 Map<String,Map<String,dynamic>> temp;

  temp = {
    "receiver": {
      "Bank": {"accounnt": '123'}
    }
  };
  if(temp['receiver']!['school'] == null){
    temp['receiver']!['school'] = '12';
  }
  print(temp);
}
