How to get content from json with SharedPreferences- Flutter/Dart - flutter

Question

How can I get only content from this json:
{
id: 2,
profileImage: {
id: 1,
fileId: "e8ec429d-1e09-48c9-9ec8-6e61c1177324.jpg",
content: "http://localhost/file/e8ec429d-1e09-48c9-9ec8-6e61c1177324.jpg"
}
}
I want to get him from response after my login request using sharedpreferences:
Future<bool> makeLoginRequest(String email, password) async {
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();
Map data = {
'email': emailController.text,
'password': passwordController.text
};
var jsonResponse;
var url = 'http://10.0.2.2:80/user/login';
var response = await http.post(url, body: data);
if (response.statusCode == 200) {
_isLoading = false;
jsonResponse = json.decode(response.body);
setState((){
Navigator.of(context).pushAndRemoveUntil(
MaterialPageRoute(builder: (BuildContext context) => NavBar()),
(Route<dynamic> route) => false);
});
return true;
} else {
return false;
}
}
thanks for any help :)

If you just need the content String you can do something like:
String content = jsonResponse['profileImage']['content'];
However a couple of recommendations, I would separate the parsing logic from the networking logic and in general try to have Model objects to map the models you receive from your services (network/storage) instead of extracting directly its content. For a trivial use case like this it's fine but for more complex scenarios it will allow you to write cleaner and more testable code.
