You’re aware of the basics of what Flutter is, don’t you? The brainchild of Google, Flutter is a mobile-based development platform that makes use of Dart to program, allowing developers to create high-quality low-cost applications that work on Android, iOS, and other platforms. To make it simpler and enjoyable, Flutter offers numerous packages which are usually free to help you meet all of your Flutter project requirements quickly (okay this is a little bit of an exaggeration).
There are more than (whopping …) 24,000 packages that are available in the Pub. dev ecosystem, which is an official repository for packages to Flutter and Dart applications. The most appealing part is that the framework allows sharing of packages that are developed and created by other developers who contribute to Flutter as well as Dart packages ecosystems (you can also contribute to the ecosystem to the ecosystem, too). What exactly is a package you might ask (don’t say it, dude)?
Well, The term “package” refers to an assortment of codes that you can integrate into your application to make it easier and user-friendly. Flutter offers a convenient method to organize closely related code and make it easier to locate and utilize. So, by putting together related code into a package you can reuse them in different projects too.
Additionally, Futter packages are similar to modules from npm, but they’re distributed as a part of an entire package, not global. Flutter developers can make use of packages to create quick and simple mobile applications without having to construct the entire application from scratch (that’s the kind of thing you’ll be looking at).
List of Top Dart and Flutter Packages
The file structure on various devices differs depending on the operating system they are running; for instance, Android’s file structure differs from Windows’s, iOS’s as well as Linux’s. Thus downloaded files and temporary files and application documents are saved in various locations. This is where the Path_provider plugin is useful. The Flutter plugin supports iOS, Android, Windows, Linux, and macOS and helps locate the locations of both public and private files on the file system.
This package allows access to your mobile device’s camera and gallery, allowing various images to be selected within Flutter’s application. Image_picker supports iOS as well as Android.
Every app must incorporate a map to ensure that users don’t need to exit the app when they need navigation, such as to keep track of the order or to provide accurate addresses. Therefore, this Flutter package lets you easily incorporate Google Maps into your Flutter Android and iOS application.
SQFLite is an independent, reliable, and embedded extension for SQLite and functions in the role of a data engine that is compatible with iOS as well as Android. It lets you keep data in your local database and execute CRUD operations such as creating, deleting, updating, and more.
FL_Chart is a vast chart library with a high degree of customization which allows you to display the amount of data you have in simple and digestible charts. It also makes it easier the process of predicting future and current trends. This is an essential package to create highly intensive apps that require data. It supports Bar charts Pie charts, Line charts, charts with Radar, and many more.
It’s a Flutter-based plugin that allows OAuth sign-in processes that use FirebaseAuth. Apart from supporting Apple Sign-In with Firebase, The plugin is compatible with Android, iOS, and the Web. When authentication via App is selected it opens a pop-up over the application, which allows the user to sign in. If sign-in through Apple is selected the native flow is employed.

It is a way to separate business logic from UI. Thus, using flutter_bloc the state of your application is broken down into smaller, well-defined state machines that transform events into one, zero, or more states.
With Code coverage, you can produce a report detailing the extent to which your tests are covered by aggregating the data of every local package into an all-encompassing data set. Additionally, the dart program assures that every line of code has been tested and functions as expected. It also lets you gather, format, and alter coverage data. It is possible to collect coverage data using the Dart VM and then format the data to attractively printed and LCOV format.
For loading assets (images animations, fonts, images configuration files, etc.) in Flutter generally, you need to use path strings. This is the riskiest way to go. As an assertion error may occur if you make a mistake in writing an incorrect path for the asset.
The Flutter_gen package will help you get free of APIs that use strings. The package functions as an asset generator that generates code such as fonts, colors, and fonts. With this package, you can easily generate compile-safe asset references, without having to worry about assertion errors.
With the Flutter Connectivity plugin, apps are able and configure networks even when they aren’t associated with the Internet. It also differentiates between wireless and WiFi networks that are available on the device.
