I'm fetching data from the server, getting the issue in parsing, The key is present in response but showing null every time.

I paste your json string to https://app.quicktype.io/ and get correct structure
and simulate your json with a text file in web server
I have print deal banner image url to prove it work fine without error
you can parse your json string with this command
final home = homeFromJson(jsonString);

//
// final home = homeFromJson(jsonString);
