How to Connect Flutter With MongoDB

Sometimes a user may have a website build with node js and MongoDB. And now user wants to create a mobile app with flutter. So, in this article, you will get to know how to connect Flutter with MongoDB.

MongoDB is one of the popular open-source NoSQL databases. In this article, we will take a look at how we can use it in flutter apps.

Are you ready for the same? So, Let’s start learning.

How to Connect Flutter With MongoDB ??

First, you need to import the flutter library mongo_dart and connect it to the database. mongo_dart is a Server-side driver library for MongoDB implemented in pure Dart. The server-side accepts all packages using dart: io, dart: HTML.

So, Consider a code snippet like the below:

import 'package:mongo_dart/mongo_dart.dart' show Db, DbCollection;
class DBConnection {

  static DBConnection _instance;

  final String _host = "DATABASE SERVER";
  final String _port = "DATABASE PORT";
  final String _dbName = "DATABASE NAME";
  Db _db;

  static getInstance(){
    if(_instance == null) {
      _instance = DBConnection();
    }
    return _instance;
  }

  Future<Db> getConnection() async{
    if (_db == null){
      try {
        _db = Db(_getConnectionString());
        await _db.open();
      } catch(e){
        print(e);
      }
    }
    return _db;
  }

  _getConnectionString(){
    return "mongodb://$_host:$_port/$_dbName";
  }

  closeConnection() {
    _db.close();
  }

}

Things to keep in mind:

  1. Firstly, If you have API then it’s not a good idea to write complete login again!
  2. Secondly, mongo_dart is an unofficial package (there is no official package).
