Right Database For Your Flutter App

An ideal flutter application needs a flawless database that can handle millions of data and regular updates. And hence the selection of the right fit database plays a crucial role in Flutter app development.

Since you have landed upon this page, we assume that you are probably new to Flutter databases, or your current database doesn’t support you adequately, and hence you are looking for some options. Well, we will cover both cases. We will begin with the Flutter database introduction, discuss its types, and then shift to the various database options.

Types of Databases For Flutter Mobile App Development

Flutter database:

In general, a database is a storehouse of collected data that can be accessed electronically from any device. The data stored can be accessed, modified, updated, controlled, and organized as per the requirements.

The app-focus trend demands real-time data delivery, which means the search query data should be latest, updated every time it is requested by the end-users. If the application fails to do so, the ball goes into someone else’s court. Well, you can not miss out on an opportunity to impress users with your Flutter app, can you?

And therefore, it is important to hire the right Flutter app development company that will not miss upon any single detail while choosing the right database for your mobile app. They will understand your project’s ins and outs and help you decide which database you should go for.

Types of Databases for Flutter mobile app development:


In this database type, the data is stored traditionally, and a relationship is created between the data. SQL and SQLite is an example of a relational database.

Non-relational database/NoSQL:

In this database type, the data is stored as a document, and no relationship is established between the data. NoSQL database holds the potential to handle huge unstructured pieces of data efficiently. A well-known example of a NoSQL database is MongoDB.

If you are to choose the right database for your Flutter app, here are some criteria that you should consider before you initiate your flutter app development.

1.Structure of your data:

The structure of your data means how you wish to store and retrieve the data. Let us elaborate it further; you should decide whether you want to store the data offline on the device or on the server.

2.Size of the data:

If you are planning to develop an app that deals with a lot of customer data, storage & retrieving of the same is a concern. Also, the collected data will need to be differentiated across multiple locations & servers. Your selected database should have the potential to handle this differentiation.

3.Speed and Scale:

Depending on the flutter app idea, your project may require heavy reads and writes. And again, whichever database you choose should be able to handle the application’s input-output needs.

4.Data modeling:

Data modeling is more of data structure representation aligning it with business requirements. If your application deals with search queries or location-based features, data modeling is an important factor to consider.

5.Data security:

Data security is of the utmost importance when it comes to database selection. The reason being, the data stored over the database is accessed, managed, and stored by many users putting the data security at risk. Hence, while selecting a database, one needs to check for database security compliance.

6.Support for multiple mobile app platforms:

Your selected database should extend support to the platform you are targeting your app on.

If these criteria are clear to you, we will go ahead with the available options of flutter databases. If not, you can connect with our Flutter app development experts. They will guide you through the basics and benefits of the databases in depth.

Flutter Database Options:

Types of Databases For Flutter Mobile App Development

Relational Database:


SQLite for Flutter is referred to as SQflite. SQflite gives complete control to the user over the database, queries into your hand.

Benefits of SQflite:

- You have complete control over the database;

- It allows you to access the SQLite database using third-party apps;

- If you have hands-on experience using SQLite, you can make efficient use of the SQflite.

Downsides of SQflite:

- It is a time-consuming process to write all the queries manually;

- SQflite doesn’t support web;

- You might face challenges if you have to migrate the project on devices;

Recommended when:

You need to have a relationship set up between the data, and you don’t mind writing your queries manually.

NoSQL/Non-relational database:

Firebase and Hive are two popular options when it comes to non-relational databases; however, both are vastly different from each other. Firebase syncs with an online store, but the Hive doesn’t have the capacity to store it; instead, It stores on local devices.


Firebase is developed by Google where the data is stored in tables in string, int, etc format. You can build applications faster without worrying about infrastructure management. It is a toolset that allows you to build whatever you can and grow relatively. Even though it is a non-relational database, it still allows you to set up relations between the data if you wish to.

Firebase is hosted in the cloud, allowing Firebase to connect with backend services directly. You can have data synchronization between client-side and server without the need for any middleware. Which further means you will write a query only in the front-end and not the back-end.

Firebase will allow multiple users to interact with the same data effectively without interrupting the query.

Benefits of Firebase:

- It provides helpful utilities for flutter app development;

- Firebase likes opensource and makes it extremely easy for developers to build a project;

- It allows you to use Firebase Console to access data using a browser.

The downside of Firebase:

- You might face difficulty in setting up Firebase on your respective device;

- When it comes to the Flutter app database for your application, Firebase isn’t in a production-ready environment;

- You should be aware of the permissions you give to the database since it is storing the data online.


Hive is a favorable database option for Flutter development. If you ask any of the Flutter app development companies or your hired Flutter app developers, you will have a unanimous decision of using Hive as a database option.

Hive complements Dart, and this means you can integrate it easily with Dart. The data is stored as HiveObject in a box that can be accessed by you.

Hive is best suited for projects that require you to store data on the device and access it anywhere.

Which one should you use?

These are some of the popular mobile application database options you have at your disposal. However, the last choice of selection is completely upon the entrepreneur to decide. The reason being, the type of Flutter mobile application you are planning to develop will decide what type of database you need.

To round up, if you wish to have a quick development, go for Hive; if you wish synchronization between devices, go for Firebase.
