flutter json_serializable missing file

Question

i don't seem to understand why it is showing the error i have created two different .g.dart files

but for this file it shows missing part. [WARNING] json_serializable:json_serializable on lib/Model/Supermodel.dart: Missing "part 'Supermodel.g.dart';".

import 'package:flutter_app/Model/addproductmodel.dart';
import 'package:json_annotation/json_annotation.dart';

part 'SuperModel.g.dart';

@JsonSerializable()
class SuperModel {
  List<addproductmodel> data;
  SuperModel({this.data});
  factory SuperModel.fromJson(Map<String, dynamic> json) =>
      _$SuperModelFromJson(json);
  Map<String, dynamic> toJson() => _$SuperModelToJson(this);
}

Answer 1

Probably an old question to answer and got me here looking for an answer to similar situation.

What I did notice for my fix and I believe it is the same in your case, is that file naming is case sensitive. Considering your model file name is Supermodel.dart your part name should be part 'Supermodel.g.dart'; instead of part 'SuperModel.g.dart';

The same case sensitive name is evident in the warning message too.

Answer 2

The "g" in ".g.dart" stands for generated. You are not supposed to create them yourself. Instead you can generate them using build_runner for example:

flutter pub run build_runner build --delete-conflicting-outputs

This will generate the missing files.

Answer 3

1- check the name of the file is it the same with capital and small letter .
2- click on Ctrl + s before run the commend .

Answer 4

Generated file name should be same like your file name, not same like class name.it is case sensitive also.
