          content:
            application/json:
              schema:
                type: array

      properties:
        id:
          type: string
          required: true
          nullable: false

In result after build_runner, I have String? id:

import 'package:freezed_annotation/freezed_annotation.dart';

part 'chat.freezed.dart';
part 'chat.g.dart';

@Freezed()
class Chat with _$Chat {
  const factory Chat({
    String? id,
  }) = _Chat;

  factory Chat.fromJson(Map<String, Object?> json) => _$ChatFromJson(json);
}

I need required String id :

import 'package:freezed_annotation/freezed_annotation.dart';

part 'chat.freezed.dart';
part 'chat.g.dart';

@Freezed()
class Chat with _$Chat {
  const factory Chat({
    required String id,
  }) = _Chat;

  factory Chat.fromJson(Map<String, Object?> json) => _$ChatFromJson(json);
}

I solved. I should use

ChatMessage:
  type: object
  required:
     - id
