Add Category with Floating Button

What I've done is creating token by authenticating through Postman and then adding it to global variable so it can be used before we get to the Register/Login through the app.

class ApiService {
 
  ApiService();
 
  String token = "your------toke";
  final String baseURL = "http://your-base-url:8000/api/";
 
  Future<List<Category>> fetchCategories() async {
    http.Response response = await http.get(
        Uri.parse(baseURL + "categories"),
        headers: {
          HttpHeaders.contentTypeHeader: 'application/json',
          HttpHeaders.acceptHeader: 'application/json',
          HttpHeaders.authorizationHeader: 'Bearer $token',
        }
    );
    print(response.body);
    List categories = jsonDecode(response.body);
    return categories.map((category) => new Category.fromJson(category)).toList();
  }
}
 
class Category {
  int id;
  String name;
 
  Category({
    required this.id,
    required this.name,
  });
  factory Category.fromJson(Map<String, dynamic> json) {
    return Category(
      id: json['id'],
      name: json['name'],
    );
  }
}
