Well explained

[@abhayshandle]

well we can use dart:convert too, why make it so complicated? idk lemme know if m missing on something, just call on jsonDecode(jsonStr), and jsonEncode(jsonStr), and ig ur work is done?

[@RohitSemriwal]

jsonDecode(jsonStr) takes the JSON string and converts it to a Map/Array in Dart/Flutter.
jsonEncode(obj) takes the Map/Array and converts it to a JSON String (reverse of jsonDecode).
But when using custom models(classes).. let's say a UserModel, it is required to convert it to a map first before encoding it to a JSON String.
Same goes for the decoding, jsonDecode(str) will decode the String and give us a map.. but we'll have to assign the values from the map to the corresponding properties in your custom class.
So basically, jsonEncode and jsonDecode work with Maps and Strings only.
Adding custom classes introduces a new level of conversion to be done.
Your statement is true only if you're using Maps for everything in your app, which is just not recommended at all.

[@abhayshandle]

@@RohitSemriwal yeah, here's what gemini had to say, i mean yeah we shouldn't practice something like that, technically Flutter can understand and work with JSON data directly using objects. However, converting JSON to custom Dart objects offers several advantages over relying solely on maps:While directly using maps for JSON data is technically possible in Flutter, it's generally recommended to create custom objects for the reasons mentioned above. The extra step of conversion provides benefits in terms of type safety, code readability, maintainability, functionality, and library integration.

sir mere 3 Question hai
1)vscode me flutter app bna ny k liye android studio ko install krna
or android studio me uski sdk android version ko bi download krna zarori hota hai kia ya flutter ki sdk hi thk hai
2) android studio k bagair apna mobile vscode me connect kr sakhty hai flutter app launch krny k liye
3) flutter app ko pc coreDu2 windows 32 bit me bna sakhty hai

[@RohitSemriwal]

1. Haan Android Studio install Krna zaroori h kyuki flutter code end me compile Android studio ke SDK se hi hota h.
2. Baat sirf Android Studio ki nhi h, Android studio ke sath sath bohot saari aur cheezein jaise command line tools, platforms, SDKs aur sab aata h. Uski wajah se wo to use Krna hi padega. Uske bina ye sab alag se install krne me saalon jaaenge😂
3. Nhi bana skte, aur agar bana skte h to bohot bura experience rahega.

Sir iam very confused how to fetch complex data from api like nested objects , fetch data from list of array. Can. U give me some hint or idea like how to deserialize nested objects clearly
