Dart cannot generate "prisma_client.g.dart" from Prisma client

I have a flutter application that I want to use SQLite database with Prisma ORM based on the work done at https://prisma.pub.

everything seems to work fine until I run the command dart run build_runner build then it fails to generate the dart prisma client to work with the Prisma generated Client.

This is the prisma schema I'm working with for now

generator client {
  provider = "dart run orm"
}

datasource db {
  provider = "sqlite"
  url      = "file:./source.db"
}

model User {
  id        String   @id @default(uuid())
  email     String   @unique
  firstname String?
  lastname  String?
  userpass  String
  role      String
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  status    Boolean  @default(true)
  userID    String?  @unique
}

on running npx prisma generate,

the prisma client is successfully generated and expects this file

part 'prisma_client.g.dart';

however when I run

dart run build_runner build

I get the following error:

$ dart run build_runner build
[INFO] Generating build script completed, took 296ms

Could not generate `fromJson` code for `equals`.
To support the type `InvalidType` you can:
* Use `JsonConverter`
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonConverter-class.html
* Use `JsonKey` fields `fromJson` and `toJson`
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonKey/fromJson.html
  https://pub.dev/documentation/json_annotation/latest/json_annotation/JsonKey/toJson.html

    │                              ^^^^^^

Since i would be adding more models, I would like a permanent solution to this so that I dont have to manually code the toJson of every unavailable data type conversion error that will arise.

I have searched onlne but it seems there is very little engagement with this stack combination, any help in any form will be very much appreciated. thank you.

Solution

  • what he said :

    Unfortunately, Prisma for Dart does not currently support Prisma 5.x version (due to huge changes). Also you should see my tweets, I am now committed to my normal life due to the bankruptcy of my company. I'm really sorry, I don't know when I will have time to come back and continue to maintain it, but I have always paid attention to this project. Once I get my debt out of the way, I'll go back to open source and continue maintaining Prisma for Dart.
