FirebaseSyncAdapter class abstract

Firebase Firestore adapter stub.

To use: add cloud_firestore to your app's pubspec.yaml, then implement the methods using the Firestore SDK.

import 'package:cloud_firestore/cloud_firestore.dart';

class MyFirebaseAdapter extends FirebaseSyncAdapter {
  final FirebaseFirestore _firestore = FirebaseFirestore.instance;

  @override
  Future<SyncAdapterResult> push(SyncOperation operation) async {
    final ref = _firestore.collection(operation.collection);
    switch (operation.type) {
      case OperationType.create:
        final doc = await ref.add(operation.data);
        return SyncAdapterResult.success({'id': doc.id, ...operation.data});
      case OperationType.update:
        await ref.doc(operation.recordId).update(operation.data);
        return SyncAdapterResult.success(operation.data);
      case OperationType.delete:
        await ref.doc(operation.recordId).delete();
        return SyncAdapterResult.success({});
      default:
        return SyncAdapterResult.success(operation.data);
    }
  }
  // ... implement pull and pullAll
}
