Exploring Flutter’s Widget Catalog: A Guide for Developers

Want to know about Flutter’s Widget? Looking to dive deep into Flutter App Development? If so, then you are at the right place! This blog is surely worthy to read if you want to know about Flutter. Nowadays, we’re gonna talk about widgets in Flutter! 

By the end of this blog, you’ll have a comprehensive understanding of Flutter widgets as well as how you can learn the entire widget catalog & work with them. Let us get started…

Flutter Widgets and their importance?

Before initiating to read this blog, Do you have any idea about Flutter Framework? How does Flutter work? How can you get started with Flutter? If you are completely unaware of all these. Then this blog is worth reading, as by reading this blog you will get to know or learn everything you need to get started with Flutter!

Now, let us initiate by knowing what these Widgets are. Widgets are the most vital thing especially while building mobile apps with Flutter, why? The reason behind this is everything, literally every single component of the mobile application or User Interface you see is a widget. Let us illustrate…

If you see any page of any website, then here each and every single component you can see is a widget. For if there is a chart bar, Navigation bar, or any button available on the page is the widget itself. A bunch of widgets are all put together or stacked on each other to create a User Interface.

Widgets are the creating blocks of the User Interface with Flutter!

Now to explain these widgets, Flutter Widgets are building blocks that let you develop the User Interface of your mobile app. They are a collection of reusable User Interface elements that assist you build complex as well as responsive UI for your mobile application. Think of them as the different kinds of Lego blocks that you can utilize to build a Lego house. As already mentioned above, you can utilize Widgets to build sliders, images, buttons, text fields, and any other User Interface element that you require for your mobile app.

But widgets are not just UI elements! In actuality, they are small pieces of code that contain instructions in which a few instructions are given on how to show or display something on the mobile screen. This implies that you can customize each Widget to behave as well as look the way you willing it to.

Flutter’s Widgets are pieces of code, which means you can wire data, as well as write functions or code such that the widget performs & behaves the way you willing it to. 

This approach to creating a User Interface is called “UI as Code”.

A simplest sample text widget can be created as shown below:

To add-on to it, the Flutter framework gives us a huge range of widgets that anyone can utilize to develop their mobile app. There are different kinds of states, styles, and types. Let us dive right into them!

Different kinds of Widgets

Flutter gives us comprehensive widgets. But for now, you need to know that widgets are mainly of 2 different types. 

Material Design & Cupertino Design

As we all know flutter lets us develop apps cross-platform.

Material design is a set of styles widgets or the design language that are built by Google, are utilized by default, & are primarily created for Android.

Material design is the default design style as all the flutter developers might not have access to a Mac to create for IOS. Material design is colorful as well as playful with rounded corners and more (Why do not you try them out & see for yourself?)

On the other hand, We have another kind of widget named Cupertino Design. This is the language or design style that is developed and utilized to create IOS or Mac apps. This is a design language that is elegant, simple, as well as sleek with a professional look.

You can utilize both of these design styles in a single codebase as well as develop an adaptive User Interface for your mobile application.

Even though, you can mix & match these design styles to develop a User Interface that you like. How cool is that?

Apart from all these, there is something which is known as ‘STATE’ & the widgets you develop are often utilized inside a Stateful or Stateless Widget. 

Learning the entire widget catalog

In the above image, we got to know that the widget catalog consists of different widgets from text to animations & more. But, the question arises, how do you learn them all?

There are plenty of widgets out there and individuals usually make the mistake of trying to learn each widget. But, why? Why do you have to learn each one of widget? Well, you don’t need to learn all of them. Simply learn to search for a widget in the catalog as per your use & implement it utilizing the documentation. It is that simple.

Here’s an instance of most flutter app developers of a reliable flutter app development company India still don’t know every available widget. But they can develop wonderful mobile applications. How? Well, mobile app developers will simply plan their mobile application’s User Interface first. If they want to create an expense tracker, they will first plan their User Interface as to how we want it, like where the chart is supposed to be, How do we want the transactions to be shown, and where to be shown, etc.

That is it, planning the User Interface gets half the job done. Now, mobile app developers simply have to surf through the widget catalog as well as find the widget flutter app developers of a leading flutter mobile app development company India need to build their User Interface in a top-down approach. As developers find their widgets, Flutter has superb documentation that flutter app developers can refer to so developers can learn more about the widget as well as how to implement it in their mobile app.

Creating their User Interface piece by piece. When you do this, tell us, do you even require to learn everything?

Pro Tip: Well-organize your mobile Application better by simply breaking down your mobile application into widgets & by creating a file for a certain widget of component or so. Try to have just one widget per file. Keeps your mobile application and organization structured & easy to work with.

Documentation of Flutter is your best friend, learn to befriend any documentation, navigating as well as working with them. Around 90% of your concerns will be resolved.

The widgets’ beauty is, they might look difficult or hard to work with in the starting but as you keep working with the widget, using them, it gets very easy as well as one of the best things.

But if you practice in a continuous way then it makes it so easy that you precisely have all the properties on your tongue. The only effective way to really learn the entire catalog is to keep developing mobile apps, working with them, & practicing more and more.

You do not need to create complex applications, initiate with easy ones and get a good grip on how you can organize your mobile app, plan the User Interface, develop the widgets accordingly, work with them, & more. Keep iterating & watch yourself grow as well as become more fluent

The Final Take

In this above write-up, we have covered what exactly widgets are, why we require to utilize them in Flutter, as well as How you can learn the entire widget catalog. With good enough practice, you will be creating beautiful User Interfaces in no time! While this might seem fundamental, these are the basics that Flutter is built on. Having a good grip over this above point will take you a long way.
