There are libraries for that.
If you’re more of a do-it-yourselfer, make your own library and share it with the rest of the community in no time at all.
Adding libraries to your project is simple and can be done by adding a single line to your pubspec.
For example, if you wanted to add the sqflite library:After adding it to the file, run flutter packages get and you're good to go.
Libraries make developing Flutter apps a breeze and save a lot of time during development.
Backend DevelopmentMost apps nowadays depend on some sort of data, and that data needs to be stored somewhere so it can be displayed and worked with later on.
So keeping this in mind when looking to create apps with a new SDK, such as Flutter, is important.
Once again, Flutter apps are made using Dart, and Dart is great when it comes to backend development.
I’ve talked a lot about simplicity in this article, and backend development with Dart and Flutter is no exception to this.
It’s incredibly simple to create data-driven apps, for beginners and experts alike, but this simplicity by no means equates to a lack of quality.
To tie this in with the previous section, libraries are available so you can work with the database of your choosing.
Using the sqflite library, we can be up and running with an SQLite database fairly quickly.
And thanks to singletons, we can access the database and query it from practically anywhere without needing to recreate an object every single time.
After retrieving data from a database, you can convert that to an object using a model.
Or if you want to store an object in the database, you can convert it to JSON using the same model.
This data isn’t all that useful without a way to display it to the user.
This is where Flutter comes in with widgets such as the FutureBuilder or StreamBuilder.
If you're interested in a more in-depth look at creating data-driven apps using Flutter, SQLite, and other technologies, I encourage you to check out the article I wrote on that:Using Streams, BLoCs, and SQLite in FlutterStreams, BLoCs, and SQLite make for a great combination when it comes to working with data in your Flutter…medium.
comFinal ThoughtsWith Flutter, the possibilities are practically endless, so even super extensive apps can be created with ease.
If you develop mobile apps and have yet to give Flutter a try, I highly recommend you do as I’m sure you’ll fall in love with it as well.
After using Flutter for quite a few months, I think it’s safe to say that it’s the future of mobile development.
If not, it’s definitely a step in the right direction.
