Flutter, the most sought-after open-source framework, has gained a large following among developers since its release. Flutter uses the Dart programming language. There is a strong community for it on Dart. dev, which provides both official support and third-party packages for effective Flutter development. For iOS, Google Fuchsia, Windows, Android, and Linux, you can create stunning native apps quickly and easily with Flutter.
The best feature of Flutter is that it enables shared packages provided by other developers for usage in the Flutter & Dart ecosystem. Without having to start from scratch, this inventiveness enables developers to create an app swiftly. To handle standard software like libraries and tools, the dart ecosystem uses packages. Similar to the Git version, you may fetch packages from the local directory system or elsewhere in addition to finding publicly accessible packages in the pub. dev directory.
You may hire flutter developer that is familiar with Dart-savvy IDEs and can handle utilizing pub, which entails generating, downloading, updating, and publishing packages. On the command line, you may also use pub if necessary.
A pubspec file in a directory might represent the very minimum of a Dart package. A few pieces of package metadata are included in the pubspec. A package may also include dependencies (specified in the pubspec), libraries for Dart, applications, resources, tests, pictures, and examples.
This page includes the most well-liked packages to give you a sense of how developed Flutter is as a platform.

A powerful, user-friendly, and reasonably priced object storage service for both Android and iOS, Firebase is a flutter plugin used in the Firebase cloud storage API. Add the dependency firebase_ store to your pubspec.yaml file to utilize this plugin. It should be noted that this plugin is still being developed. Thus specific APIs might not be available quite yet.
This crucial Flutter plugin forAndroid and iOS development platforms. This package encases persistent storage libraries that are platform-specific. Processing in both batches and transactions is supported. Beginning with that point, version control is automatic. For insert, query, update, and delete queries, it offers help.
