Flutter Introduction | Flutter for Beginners

Flutter is a mobile application development framework created by Google. It uses the Dart programming language and allows for the creation of high-performance, visually attractive apps for both Android and iOS devices. It also includes a reactive programming model and a rich set of customizable widgets, making it a popular choice for developers.

Flutter uses a unique rendering engine to draw widgets on the screen, which allows for smooth and responsive animations, as well as a consistent look and feel across different platforms. It also includes a hot-reload feature that allows developers to quickly iterate on their code without having to manually rebuild and redeploy the app.

Additionally, flutter has a rich collection of packages, which are pre-built solutions that can be easily added to your app to provide additional functionality, such as networking, storage, and maps.

Flutter is open source and actively maintained by Google, with a strong and growing community of developers contributing to the framework. It is used by many companies and organizations to build high-quality, cross-platform mobile apps.

Advantages

High performance: 

 Flutter's unique rendering engine allows for smooth animations and fast app performance.

Cross-platform development: 

Flutter allows for the development of apps for both Android and iOS platforms with a single codebase.

Hot Reload: 

It allows developers to quickly iterate on their code, making the development process more efficient.

Customizable widgets: 

Flutter includes a wide range of customizable widgets, which makes it easy to create beautiful and unique user interfaces.

Strong community:

Flutter has a large and growing community of developers, which means there are many resources and third-party packages available to help with app development.

Disadvantages

Limited third-party libraries:

Flutter has a smaller ecosystem of third-party libraries compared to other frameworks such as React Native.
Large app size:

The app size can be larger than other frameworks due to the fact that it includes all the necessary components to run the app, rather than relying on the platform's built-in components.
Learning curve:

Dart, the programming language used by Flutter, is not as widely used as other languages like Java or JavaScript, so there may be a learning curve for developers who are not already familiar with it.

Risk of platform-breaking changes:

As the framework is still in development, there could be a risk of breaking changes with new releases.

 

Difference b/w Flutter and React Native 

1. Flutter and React Native are both frameworks for building mobile apps, but they have some key differences.
2. Flutter is a framework developed by Google for building high-performance, high-fidelity mobile apps for iOS and Android using a single codebase. It uses the Dart programming language and features a reactive programming model, fast development cycles, and a customizable, compostable widget set.
3. React Native, on the other hand, is a framework developed by Facebook for building mobile apps using React, a JavaScript library for building user interfaces. It allows developers to build mobile apps that look and feel native by leveraging the capabilities of the underlying platform, while still using a single codebase.
4. One key difference is that React Native uses JavaScript and React for building the app, while Flutter uses Dart. This means that React Native developers will already be familiar with the language and framework, while those with experience in web development may find it easier to pick up. Additionally, React Native has more mature tooling and a larger community, but Flutter has a more expressive and customizable UI.

What makes Flutter unique?

    Flutter is unique in several ways, some of the key features that make Flutter unique are:

1.    Reactive Programming: Flutter uses a reactive programming model which allows for the creation of responsive and high-performance apps with smooth animations and scrolling. This makes it easier to create apps that feel natural and fluid to users.
2.      Customizable widgets: Flutter includes a rich set of customizable widgets that are used to build the app's user interface. These widgets are rendered directly by the framework, which results in high performance and smooth animations.
3.      Hot Reload: Flutter supports hot-reloading, which allows developers to see the changes they make in the code immediately in the app, without having to manually rebuild and deploy the app. This makes the development process faster and more efficient.
4.    Single Codebase: Flutter allows developers to create apps for multiple platforms from a single codebase, which saves time and resources. This makes it easier to create apps for both Android and iOS, as well as for the web and desktop, from the same codebase.
5.      Dart Language: Flutter uses the Dart programming language, which is easy to learn and has a familiar syntax for developers who have experience with languages like Java and C#.
6.    High performance: Flutter's widgets are rendered directly by the framework, which means that they are not dependent on the platform's native widgets. This results in higher performance and a smoother experience.
7.   Community: Flutter has a large and growing developer community, which has contributed to the development of many plugins, packages, and other tools that can be used to add additional functionality to apps.

11.  Support for In-App Purchases: Flutter has built-in support for in-app purchases, which allows you to sell digital goods and services through your app.

H   History of Flutter

        Google developed the mobile app development framework known as Flutter. At the Dart developer summit in 2015, "Sky," the initial iteration of Flutter, was introduced. The project was initially created by a small team at Google, but it has since expanded to become one of the main development frameworks used by the business.

       Version 1.0 of Flutter, the first stable version, was published in December 2018. With the help of additional plugins and packages, this release supported the creation of mobile apps for iOS and Android as well as the web and desktop.

      Flutter has improved and changed since it was first introduced, and new features and upgrades are frequently provided. Google introduced Flutter for web in 2019, allowing programmers to construct web-based apps.s.
