Top 10 Flutter Widgets

This blog discusses our hand-picked top 10 Flutter widgets list and how they can help you revolutionize the Flutter app development.

Difficult to imagine, but yes, it is possible to have your Flutter app without coding! Wondering how? Widget is the answer. Flutter is full of widgets, and it makes it more sustainable. Flutter widgets are used for developing high-quality mobile, web, and desktop applications.

An interesting thing about why Flutter widgets are so popular is the fact that they are highly customizable and offer extensive flexibility & fluidity that can be the best fit for any mobile application type. Flutter UI widgets are optimized for higher performance and perfect development. The widget elements are organized in the form of a widget tree. The way the widgets are placed defines the operation of the front-end of the native apps screen. The two primary things of Flutter widgets are the configuration and the widget state.

With the pool of amazing Flutter widgets list available, it is difficult to pick up the top 10 Flutter widgets that you should not miss while developing a flutter application. But, we have eased out this selection process by picking up the best flutter widgets for you.

By the end of this article, you will also know which flutter widgets to use for implementing a particular functionality.

Let’s begin with a short introduction about Flutter widgets.

There are mainly two types of widgets in Flutter,

1. Stateless widget;

2. Stateful widget.

Depending on the two types, these widgets are further categorized into 14 different categories, namely,

- Accessibility;

- Assets, Images, and Icons;

- Async;

- Animation and Motion;

- Basics;

- Cupertino widget;

- Input;

- Interaction Models;

- Layout;

- Material Components;

- Painting and Effects;

- Scrolling;

- Styling;

- Text;

As you would have observed, each of these widgets has its own functional implementation in mobile apps development.

Flutter ui Widgets

1. ConstrainedBox:

ConstrainedBox is a built-in widget available in Flutter SDK. It is usually used to add limitations in size to the child widgets. It allows developers to add flexibility with respect to height and width in a child widget.

However, the widget has a limitation when the child is bigger in size than that of the container. It cuts the child’s view, making the front end look a bit out of the line. This problem can be solved by not defining the maxHeight property and adjusting it to by default value of double.infinity.

2. SafeArea:

SafeArea widget is best for developing a dynamic and adaptive UI. SafeArea widget helps in adjusting the screen with various devices of varied width and height. SafeArea widget also helps in overcoming the area constraints induced by the status bar, notches, navigation bar, etc. SafeArea widget implementation doesn’t allow the design to overlay any of the areas where there is frontend UI visibility constraint and thereby makes it error-free.

Therefore SafeArea widget is also referred to as a padding widget that adds padding to android or iOS apps wherever there is a constraint.

SafeArea widget will also indent the child with the necessary padding requirement, especially for the devices with the Notch like iPhone X.

3. Motion Tab Bar:

It is an awesome animated widget used for animating the tab bar and moving it as per the theme.

Flutter ui Widgets

4. FittedBox:

FittedBox is a responsive Flutter widget. It helps in inducing responsiveness into the single child assigned to it.

You need to add a Row widget as a child in this particular FittedBox widget. Row widget itself has two containers as its children. In this scenario, the second child will overflow to one side, but this issue is resolved with the FittedBox widget.

FittedBox widget is used to scale and position the child widget inside the parent widget. The UI developed using the FittedBox widget is clean, crisp, and dynamic. You can use the FittedBox class and enter a child widget while using the FittedBox widget.

5. Opacity:

Opacity widget is used to make a child inside the container transparent. It changes the child into an intermediate buffer and makes it transparent temporarily.

The remaining space rearranges itself, or you can keep it empty; you can do it both ways.

Flutter ui Widgets

6. Wrap:

Wrap widget in Flutter is used to wrap children in a horizontal and vertical placement. Suppose you have multiple widgets and you want to use them in a row or a column; you can use the Wrap widget to prevent the content from getting clipped.

You can name a direction, i.e., either horizontal or vertical, depending on the frontend you want to have for your application. It also helps in defining the spacing between the two widgets.

Flutter ui Widgets

7. Flutter Arc Text:

Another interesting Flutter widget on the list is Arc Text. Arc Text widget helps in simplifying the task of writing a code for a text and content available over an arc shape.

You can set various angles and define the content you want to have around the circle, which is next to impossible to code with Flutter.

If you hire Flutter developers from anywhere in the world, they will implement the same widget if you demand to have a frontend UI over an arc.

Flutter ui Widgets

8. FloatingActionButton:

Every Flutter programmer, newbie, or have years of experience uses FloatingActionButton during app development. It is a hovering action button used to draw attention to a particular element of the app content. FloatingActionButton is one of the main widgets of the Scaffold widget.

Flutter ui Widgets

9. Numeric Keyboard:

This widget brings an end to the hassle of developing a custom number pad in an application. You can use the Numeric Keyboard widget directly, and it comes with no package for Android or iOS.

Flutter ui Widgets

10. StreamBuilder:

StreamBuilder widget is used to synchronize the streams of received data. The widget is backed by Dart language that extends its support to asynchronous streams of data. StreamBuilder widget takes in two arguments,

- A Stream;

- A Builder.

The widget acts as a pipe that receives an entered data from one end and releases it at the other end. Additionally, registered listeners can be multiple in numbers.
