Masamune Model Firebase Data Connect Annotation

Overview

masamune_model_firebase_data_connect_annotation provides annotations for code generation with Firebase Data Connect. This is a companion package that works with the builder and runtime packages.

Package Roles:

• masamune_model_firebase_data_connect_annotation (this package) - Provides annotations
• masamune_model_firebase_data_connect_builder - Generates GraphQL schemas and adapters
• masamune_model_firebase_data_connect - Runtime adapter implementation

Usage

This package is automatically included when you use the full Firebase Data Connect stack. Install all three packages:

flutter pub add masamune_model_firebase_data_connect
flutter pub add masamune_model_firebase_data_connect_annotation
flutter pub add --dev masamune_model_firebase_data_connect_builder

Annotations

@firebaseDataConnect

Mark models that should generate Firebase Data Connect schemas with permission settings:

import 'package:masamune_model_firebase_data_connect_annotation/masamune_model_firebase_data_connect_annotation.dart';

@freezed
@formValue
@immutable
@firebaseDataConnect  // Enables Data Connect generation
@CollectionModelPath(
  'user',
  permission: [
    AllowReadModelPermissionQuery.allUsers(),   // All users can read
    AllowWriteModelPermissionQuery.allUsers(),  // All users can write
  ],
)
class UserModel with _$UserModel {
  const factory UserModel({
    required String name,
    @Default('') String email,
  }) = _UserModel;
  // ... rest of model
}

@FirebaseDataConnectAdapter

Configure custom adapter settings:

@FirebaseDataConnectAdapter(
  connector: "my-connector",     // Connector name
  service: "my-service",         // Service name
  location: "us-central1",       // Cloud location
  outputDirectory: "firebase/dataconnect",  // Output path
)
@firebaseDataConnect
@CollectionModelPath('post')
class PostModel with _$PostModel {
  // ... model definition
}

Code Generation

After annotating your models, run:

katana code generate

This generates:

• GraphQL schema files (.gql)
• Query and mutation definitions
• connector.yaml configuration
• *.dataconnect.dart adapter implementations
