Usage #

create project #

mkdir my_project
cd my_project
firebase init functions
mkdir functions/node

my_project/functions/node/main.dart #

import 'package:firebase_node/functions.dart';
import 'package:firebase_node/admin.dart' as admin;

void main() {
  functions['onCreateUser'] =
      functions.auth.user().onCreate((user, context) async {
    final app = await admin.initializeApp();
    final ref = app.firestore().collection('userdata').doc(user.uid);
    await ref.set({
      'name': user.displayName,
      'email': user.email,
      'timestamp': admin.FieldValue.serverTimestamp(),
    });
  });

  functions['onDeleteUser'] = functions.auth.user().onDelete(onDeleteUser);

  functions['storageFunctions'] = functions.storage
      .bucket('my-bucket')
      .object()
      .onFinalize((metadata, context) async {
    final app = admin.initializeApp();
    final ref = app.firestore().collection('tracker').doc('my-bucket');
    final fileName = metadata.name;
    final fileSize = metadata.size;
    final fileId = metadata.id;
    final timestamp =
        admin.Timestamp.fromDateTime(DateTime.parse(metadata.updated));
    final data = {
      'file.$fileId': {
        'name': fileName,
        'size': fileSize,
        'timestamp': timestamp,
      },
      'file_count': admin.FieldValue.increment(1),
    };
    await ref.update(data: data);
  });
}

Future<void> onDeleteUser(UserRecord user, EventContext context) async {
  final app = await admin.initializeApp();
  final ref = app.firestore().collection('userdata').doc(user.uid);
  await ref.delete();
}
