How to use FreezedUnionCase.snake for model class

Question

I am using freezed package as a code generator. My response from API as shown below,

first_name, 
last_name, 
etc..,

And I am defining my model class like this,

firstName,
lastName,
etc..,

If I use @JsonKey(name: 'first_name') then it works but I have to write this annotation for every field I have. Is there any way to set it global?

Someone has already answered the class based solution, however if you are looking for somehow configure it globally, you can do it by adding a build.yaml file to the root of your project and configure it like below:

targets:
  $default:
    builders:
      json_serializable:
        options:
          field_rename: snake

and you set the value based on the json_serialization enum:

/// Values for the automatic field renaming behavior for [JsonSerializable].
enum FieldRename {
  /// Use the field name without changes.
  none,

  /// Encodes a field named `kebabCase` with a JSON key `kebab-case`.
  kebab,

  /// Encodes a field named `snakeCase` with a JSON key `snake_case`.
  snake,

  /// Encodes a field named `pascalCase` with a JSON key `PascalCase`.
  pascal,

  /// Encodes a field named `screamingSnakeCase` with a JSON key
  /// `SCREAMING_SNAKE_CASE`
  screamingSnake,
}
