Generated freezed file has undefined class error

[dannyatthaya]

When I run the dart run build_runner build command, the generated file has errors which is Undefined class '$PrismaNullCopyWith'. This happens when you have prisma scheme nullable field (everything works out when you don't have nullable field).

The dependencies that I have is:

dependencies:
  orm: ^2.6.0
dev_dependencies:
  build_runner: ^2.3.3
  freezed: ^2.3.2
  json_serializable: ^6.5.4

The scheme that I have is:

generator client {
  provider = "prisma-client-dart"
}

datasource db {
  provider = "mysql"
  url      = env("DATABASE_URL")
}

model User {
  id        Int      @id @default(autoincrement())
  email     String   @unique
  name      String
  post      Post?    @relation(fields: [postId], references: [id])
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  postId    Int
}

model Post {
  id        Int      @id @default(autoincrement())
  name      String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  User      User[]
}

Here is the screenshot of the errors:

@dannyatthaya There is a temporary fix:

build.yaml

targets:
  $default:
    builders:
      freezed:
        options:
          copy_with: false
          equal: false

I will fix this problem in the next version as soon as possible.

@dannyatthaya Fixed in 2.6.1 version
