17 Top Flutter Widgets You Can Use For Your Business App Development in 2024

Last Updated on May 28, 2024

Quick Summary

Flutter is a robust and reliable SDK by Google for cross-platform mobile app development. It is renowned for building performant applications and is easy to maintain. Within the Flutter ecosystem, the Flutter widgets play a crucial role in developing next-gen applications quickly, saving significant time and frustration during the development process. In this blog post, we will deeply understand everything that is there to know about the best Flutter widgets. Also, we will explore the 17 Top Flutter widgets that can come in handy when building fast and efficient business applications.

What are Flutter Widgets?

Flutter is a renowned framework for cross-platform application development with benefits such as an efficient development process, performance, active community, and more. However, the one thing that makes it outperform other cross-platform frameworks is the extensive widget ecosystem. In Flutter, widgets are the foundational elements that compose the user interface. Every visual component on the screen is a widget, from basic buttons to complex layouts, including buttons, text fields, images, containers, and beyond. The top Flutter widgets are lightweight, highly reusable, and compositional. This Flutter widgets cheat sheet will help your development teams find the right Flutter widget for your business application development, enabling you to create sophisticated UIs by assembling simpler widgets.

Types of Widgets in Flutter

The “State” in a widget refers to the information that can be read asynchronously when built and might change during its lifetime. Based on this state, the widgets in Flutter are divided into Stateless Widgets and Stateful Widgets.

Flutter Stateless Widgets

The Stateless Widgets in Flutter refer to widgets that cannot be changed once constructed. Once built, these widgets remain immutable, meaning any alterations, variations, icons, buttons, or data retrieval cannot modify the application’s state. A typical stateless widget structure overrides the build() method and returns a widget.

Some examples of Stateless widgets include text or Icon widgets within a Flutter application that exemplifies stateless widgets, where the widget’s state remains constant during runtime. These are employed when the UI solely depends on the information within the object. Other illustrations include Text, Raised Buttons, and Icon Buttons.

Example: Stateless Widget

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
const MyApp({super.key});

@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
leading: const Icon(Icons.menu),
backgroundColor: Colors.green,
title: const Text(
"Hello World",
textAlign: TextAlign.start,
),
),
body: const Center(
child: Text(
"Stateless Widget",
style: TextStyle(color: Colors.black, fontSize: 30),
),
),
),
);
}
}

Stateful Widgets refer to widgets that can be altered once built. Unlike stateless widgets, the state of stateful widgets is changeable and can be updated multiple times throughout their lifecycle. The basic structure of a stateful widget requires overriding the createState() method and returning a State object. Stateful widgets are employed when the UI changes dynamically based on user interactions.

Examples of Flutter stateful widgets include Checkboxes, Radio Buttons, Forms, and Text Fields. The Classes that inherit the “Stateful Widget” are immutable, but the State is mutable and changes in the runtime when the user interacts with it.

Example: Stateful Widget

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);

@override
State createState() => _MyAppState();
}

class _MyAppState extends State {
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
leading: const Icon(Icons.menu),
backgroundColor: Colors.green,
title: const Text(
"Hello World",
textAlign: TextAlign.start,
),
),
body: const Center(
child: Text(
"StateFul Widget",
style: TextStyle(color: Colors.black, fontSize: 30),
),
),
),
);
}
}

17 Top Flutter Widgets Commonly Used In App Development

Flutter offers extensive libraries, tools, packages, and plugins for your business applications. The same is the case with Flutter widgets; below is a list of the top Flutter Widgets you can use within your Flutter development project to improve the overall end-user experience based on your development needs and requirements.

1. FittedBox

It is another highly responsive Flutter widget that helps provide responsiveness to the assigned single-child option with the best of requisites and the perfect exclusiveness. Within the process, you must add the row widget with the two containers and the children. The second child here is sure to overflow the one already there on the side, and the problem is that it is rightly solved with the FittedBox widget.

2. SafeArea

It is one of the most dynamic and adaptive widgets, helping adjust the screen and the proper and varied devices depending on the widget’s height and width. The SafeArea widget also helps eliminate the real-time area constraints induced and introduced by the status bar.

Wrap the widget in Flutter and use it to wrap the children in horizontal and vertical motions. If you have a variety of widgets and wish to use them in a specific row or column, you can use the wrapped widget right from protecting the content to get clipped. Upon reaching the edge, it automatically moves the content to the next line or column, ensuring a responsive and uncluttered Flutter layout. The Wrap widget is handy for creating tag clouds or chip groups with dynamic content sizes.

4. Motion Tab Bar

It is another Flutter widget that allows motion animation for your tab bar. You can use this widget to animate the tab bar within your Flutter app and quickly move it based on its theme and subject matter.

5. Opacity

It is another widget that lets you make the child transparent within the container. It works fine by transforming the child into the kind on the intermediate buffer and can also temporarily make it transparent for better functionality. The remaining space will rearrange things automatically, or you can keep it empty or do things both ways.

6. FloatingActionButton

The FloatingActionButton, as the name suggests, has a specific hovering action and helps draw attention to the specific elemental points in case of the application content. It is precisely for highlighting the primary action in an application. It is a principal widget and is part of the main scaffold widget. Its circular, prominent positioning catches the user’s attention, making it perfect for creating a new message or adding a new item. Using this widget, your development teams can fully customize the appearance and behavior, tailoring it to the application theme and the user’s needs.

7. Flutter Arc Text

It is one of the most flexible and programmable widgets in the big list. It helps perform simple tasks such as writing the code for the text and the available content over the arc shape. You can easily set angles well, which will help the desired content around the circle.

8. StreamBuilder

It is a top widget in Flutter that helps synchronize the received data in time. The Dart language highly supports it, which will help extend the support for asynchronous data streams. The widget here is a perfect pipe that helps receive the entered data from one end and then release it from the other end.

9. Numeric Keyboard

It is another widget, Flutter, within the list of the best Flutter widgets that frees you from the hustle of developing the custom number pad present within the application. The numeric keyboard widget is simplified and easily used, and it is available as an open package on iOS and Android.

A container widget or Container class is a convenience widget that combines widget painting, positioning, and sizing. It is often used to store one or more widgets and position them on the screen as needed. It includes a wide range of properties such as padding, margin, height, width, and decoration, enabling properties such as padding, margin, height, width, and decoration offering extensive customization of the space and appearance of the UI elements it contains. By adjusting the properties, your development teams can achieve precise alignment and positioning, improving the overall aesthetics and functionality of the application.

Within Flutter, the ListView widget creates a scrollable list of children’s widgets. It is commonly used when many items must be displayed in a vertical or horizontal list. It caters to various content types, supports fixed and dynamic lists, and accommodates horizontal scrolling. Your development team can improve the user experience by implementing item separators and pull-to-refresh features with Flutter ListView. Its adaptability and functionality make it ideal for displaying data lists within apps.

It is one of the most fundamental Flutter components and is crucial for displaying short text within your app. It offers a variety of styling options, allowing developers to adjust the font size, color, weight, and spacing to create the desired visual impact. You can control the Text alignment and overflow, ensuring that the text perfectly fits within the layout and contributing to improving the user interface. You can use the Text widget to display labels and user input and provide instructions within the application.

This widget is essential for the horizontal layout design, helping to align the widgets side by side across the main axis. It offers properties such as mainAxisAlignment and crossAxisAlignment for controlling the alignment of its children, ensuring a responsive and well-structured layout. Your development team can use the Row widget to create horizontal lists and navigation menus and place elements such as icons and text next to each other.

This widget is a vertical counterpart to the Row widget; it aligns its children with the main axis from the top to the bottom. While it shares multiple properties with Row, like alignment and flexibility, its vertical orientation suits it for different scenarios. Developers often prefer the Column widget when they need to stack the elements vertically, such as forming a list of the text fields in a form. It is pivotal in creating complex layouts while ensuring a clean and organized UI.

It is another Amongst the Flutter UI widgets that plays a crucial role in the responsive design within the Flutter framework. It works alongside the Row and Column to distribute the space proportionally among the child widgets. It helps ensure that the available space is utilized effectively, preventing overflow and maintaining a balanced layout. Understanding how to wield the Expanded widget is important for developers who intend to build flexible and adaptive UIs.

It presents a unique approach to layout design within Flutter, allowing your development teams to overlay widgets on top of one another and create a layered structure. This is essential for scenarios that need absolute positioning, such as placing a badge over an icon or creating a carousel of images with overlaid text. By manipulating the z-axis, this widget offers an intricate and visually appealing Flutter app design, adding depth and complexity to the user interface.

The Form Widget helps gather user input in a structured and controlled manner. It stands out as a vital component in Flutter. It helps streamline form creation and offers inbuilt validation, ensuring that the data submitted by users meets the required criteria. Your development teams can create cohesive and user-friendly forms, complete with error messages and input formatting, improving the user experience.
