However, in this blog, we are going to mention the top 10 flutter packages that will help you speed up your mobile app development process tentatively. 

Let’s begin with understanding the concept of Flutter packages along with a few tips while considering any of the open-source packages. 

What are the Flutter Packages?

Flutter packages are pre-built, reusable modules of code that can be used to add functionality to Flutter app development services. They can be thought of as collections of related code that can be seamlessly integrated into a Flutter project to offer a specific feature or capability. 

Flutter packages are available on the official Flutter repository called pub.dev. By designating them as dependents in the project’s pubspec.yaml file, these packages can be downloaded and utilized in a Flutter project.

Thousands of Flutter packages are available on the pub.dev that can help developers easily add features like camera support, maps, animations, HTTP networking, and many more to their Flutter apps without having to write all the code from scratch. Developers can also create and publish Flutter packages, which makes it simple to cooperate with other Flutter developers and exchange code.

Tips Before Choosing a Flutter Package for Your App Development

Choosing the right open-source Flutter app development package determines the future of your project. Here are a few tips to consider before making your decision in picking any Flutter packages in 2023: 

Check the package popularity: 

A popular package is usually a good sign of quality, stability, and community support. Engineers can anytime check the package’s adoption in the market by searching the number of downloads, stars, and forks on the package’s repository page.

Check the package compatibility: 

While using any package for mobile app development, it is vital to check the compatibility with the latest version of Flutter and Dart. You can check the package compatibility by looking at the package’s pub.dev page or GitHub repository.

Top 10 Flutter Packages That Speed Up The Development Process

1. Flutter_bloc:

The flutter_bloc package is a Flutter package that provides a simple and elegant way to implement the BLoC (Business Logic Component) pattern, which is a state management pattern widely used in Flutter apps.

The BLoC pattern is a way to manage the state of your app by separating the presentation layer from the business logic layer. With the BLoC pattern, you create a BLoC object that contains the business logic for a particular screen or feature in your app. The BLoC object communicates with the presentation layer through streams of events and states, and the presentation layer updates its UI based on the current state of the BLoC.

Read along the top 7 Flutter state management libraries in 2023. 

The flutter_bloc package provides tools for creating and managing BLoC objects, as well as for handling the streams of events and states that are used to communicate with the presentation layer. It includes a number of classes and utilities that simplify the implementation of the BLoC pattern in your Flutter app, including:

• Bloc: A base class for creating BLoC objects.
• BlocBuilder: A widget that rebuilds its child based on the current state of a BLoC.
• BlocListener: A widget that listens for events from a BLoC and performs side effects.
• BlocProvider: A widget that provides a BLoC to its descendants via an InheritedWidget.
• BlocConsumer: A combination of BlocBuilder and BlocListener.

The flutter_bloc package also includes tools for debugging and logging your BLoC objects, including the ability to print out the current state of a BLoC and to log events and state changes.

By using the flutter_bloc package, you can implement the BLoC pattern in your Flutter app with minimal boilerplate code and a clear separation of concerns between the presentation layer and the business logic layer.

2. Make use of dio- A powerful Flutter Package

Dio is a powerful and flexible HTTP client for Dart and Flutter app development that allows you to make network requests in your app. The package is made to be straightforward yet flexible, with several choices for dealing with requests and responses.

For making HTTP queries using GET, POST, PUT, DELETE, and other HTTP methods, Dio offers a straightforward and attractive API. JSON, XML, and form-encoded data are just a few of the forms you can transmit and receive data using Dio.

Dio also includes a number of advanced features that make it an excellent choice for handling complex network requests. For example, Dio supports:

Dio is also very customizable and may be tailored to match the particular requirements of your project. You can configure Dio to use custom HTTP clients, request and response transformers, and other advanced features.

3. Flutter_svg:

The Flutter ecosystem includes a package called flutter_svg that enables the rendering of SVG (Scalable Vector Graphics) pictures in Flutter apps.

An excellent fit for use in responsive applications, SVG is an XML-based vector image format that enables graphics to be scaled up or down without sacrificing quality. You may load SVG files into flutter_svg and display them in your app just like any other image, with the extra benefit of being able to scale and modify them without losing any quality.

The flutter_svg package provides a widget called SvgPicture that you can use to display an SVG image in your application. This widget supports a variety of options for controlling the way the image is rendered, including the ability to specify a width and height, adjust the color of the image, and more.

Additionally, flutter_svg also provides APIs for programmatically manipulating SVG images, such as changing the color of specific parts of an SVG image. This can be especially useful for creating interactive applications or games that involve SVG graphics.

4. Flutter_localizations

flutter_localizations is a Flutter package that provides localization and internationalization support to Flutter apps. It contains a set of pre-built localization and internationalization resources that can be easily integrated into a Flutter app.

The package provides translations for various languages and locales, including date and time formats, numbers, and strings. It includes localized resources for several languages, such as:

• English
• Spanish
• German
• French
• Chinese & among others.

By including flutter_localizations in a Flutter app, mobile app developers can provide their app’s interface in multiple languages, making it accessible to a wider audience. This package works in conjunction with the intl package, which provides tools for formatting dates, times, and numbers in a locale-specific way.

5. Flutter_icons:

The Flutter framework’s flutter_icons package offers a collection of editable icons for use in Flutter apps. A vast variety of icons are included in it, including well-known icon sets like Material Icons, Cupertino Icons, FontAwesome, and many others.

The package allows developers to easily incorporate icons into their Flutter applications using a simple syntax. It also provides support for customizing the size, color, and other properties of the icons.

Some of the benefits of using flutter_icons include:

• A wide range of icons to choose from, covering many popular icon sets.
• The simple and easy-to-use syntax for adding icons to your Flutter app.
• Customizable icon properties, such as size and color.
• Supports both iOS and Android app development platforms.

To use flutter_icons, you can simply add it as a dependency to your Flutter project’s pubspec.yaml file, and then import the desired icon set into your project. From there, you can use the icons in your project just like any other Flutter widget.

6. shared_preferences: 

Flutter’s shared_preferences package offers a straightforward method for storing and retrieving persistent key-value pairs of data. You can quickly save little bits of information like user preferences, app settings, and other basic application states.

This package offers a platform-independent method of data storage and retrieval, making it compatible with several platforms (including iOS, Android, the web, etc.). Any component of the app can access the data because it is kept locally on the device.

The package uses the SharedPreferences API on Android and NSUserDefaults on iOS to store data. On the web platform, it uses the browser’s local storage API to store data.

Some common use cases for shared_preferences include storing user authentication tokens, saving user settings such as language preferences, and caching small amounts of data that are expensive to compute.

7. flutter_webview_plugin:

A webview (an instance of a web browser) can be embedded within a Flutter app using the flutter_webview_plugin plugin. If you need to display web content inside your app, like a news feed, an article, or an interactive web application, this can be helpful.

The plugin provides a simple API for creating and render webpages using Flutter webviews, and it supports various features like loading URLs, listening for events, handling errors, and controlling the webview’s behavior.

Here is an example of how to use flutter_webview_plugin to display a webview:

In this illustration, the webviewScaffold widget creates an app bar labelled “My WebView” and a webview with the URL “https://www.example.com”. The withZoom and withLocalStorage properties enable zooming and local storage for the webview, respectively.

Note that the flutter_webview_plugin is only compatible with Flutter projects that target Android and iOS. If you want to embed a webview in a Flutter project that targets the web, you can use the official webview_flutter plugin instead.

8. Flutter_redux: 

flutter_redux is a package in Flutter that provides an implementation of Redux architecture for state management in Flutter applications.

Redux is a predictable state container for JavaScript apps, which has been adopted by the Flutter community as a way of managing application states. Redux’s central tenet is that it stores all of your application’s state in a single store, which is updated by actions that specify how the state should change. The store then emits a new state, which is used to update the UI.

flutter_redux provides a set of widgets. It utilities that make it easy to implement the Redux architecture in your Flutter app development services. The StoreProvider widget generates a Redux store. And makes it accessible to all of the child widgets in the app. Which is the primary widget offered by the package. A widget can be connected to a specific area of the store so that it can access. And also update that area of the state using the StoreConnector widget.

Using flutter_redux can help you to write more maintainable and testable code. By separating the logic for updating the state from the UI code. Additionally, it offers a central location to manage your application’s state. Which is helpful when working with bigger, more complicated projects.

9. Provider

A Flutter “provider” package is a state management package that aids in managing the state of an application. And making it accessible to its many components.

The “provider” package provides a simple and flexible way to manage the state of an application. By using the Provider API. This API allows widgets to access the application state without having to pass it down through the widget tree manually. Instead, it uses a widget tree that creates a hierarchy of providers. That can be used to pass data to the widgets that need it.

With the Provider API, widgets can simply declare that they need a specific piece of data. And the provider will take care of providing it. This can make the code simpler and the application’s state easier to manage. Especially as it gets bigger and more complicated.

10. flutter_hooks

flutter_hooks is a package in Flutter that provides a way to use stateful widgets with the hook paradigm. Which is a programming model that allows for easier and more efficient management of state in an application.

With flutter_hooks, you can create widgets that have states that can be modified and updated. In response to user interaction or changes in the application. Use hooks that function and allow you to access and update stateful data within a widget.

Some of the key benefits of using flutter_hooks include:

• Simplifying state management: Hooks allow you to encapsulate stateful logic in a single function, making it simpler to handle state in your application.
• Improving performance: Hooks can improve the performance of your application by reducing the number of widget rebuilds that are required when the state changes.
• Enabling code reuse: Hooks can be used to extract stateful logic into separate functions that can be reused across multiple widgets. 

Wrapping Up

In conclusion, Flutter packages that speed up the app development process are a critical component in creating high-quality and efficient mobile applications. These packages provide pre-built functionalities and top tools that every developer should use in 2023 to rapidly build and deploy apps, while also reducing development time and costs.
