You just need to call bioData['nama'].remove('firstName') directly, don't need to create a copy of it. The code should look like this :

 Map<String, dynamic> biodata = {};
biodata['nama'] = {
  'firstName' : 'Andrean',
  'lastName': 'tama',
};
biodata['nama'].remove('firstName');
print(biodata['nama']);
