Introduction

Flutter is an open-source UI software development framework created by Google. It is used to develop cross-platform applications for Android, iOS, Linux, Mac, Windows, Google Fuchsia, and the web from a single codebase. It provides a simple, powerful, and efficient application in Google’s own language, Dart.

Programming Language:

Dart is an open-source general-purpose programming language. It was originally developed by Google. Dart is an object-oriented language with C-style syntax that can optionally trans compile into JavaScript. It supports a varied range of programming aids like interfaces, classes, collections, generics, and optional typing. Dart collections can be used to replicate data structures such as arrays, generics, and optional typing. Flutter uses Dart as Dart allows Flutter to avoid the need for a separate declarative layout language. The layout of Dart is declarative and programmatic and it makes it easy for developers to read and visualize it very easily and effortlessly.

Features

1. Hot Reload

However, mobile developers had to wait a few minutes for a change to the code to reflect on their screen. But, with Flutter app development, there is a feature called Hot Reload which allows developers to render changes in sub-seconds. It saves time, money, and effort. Thus, this feature enables developers and designers to have complete freedom and boosts their creativity further, and fix bugs in no time.

2. Cross-Platform development

Cross-Platform Development saves time, energy, and money. With Flutter, you need to write the code once, maintain it, and can use that for two apps. The need has gone for developing a different code for a different platform. With Flutter, you can try developing for the Fuchsia platform which is a trial OS in process at Google.

3. Open Source

Google introduced Flutter as an open-source platform. Various design options can be explored by developers to create Flutter applications. User-friendly applications can be created with Material Design and Cupertino widgets. Flutter Form is a community of Flutter enthusiasts who come together to answer questions related to Flutter and discuss it. Flutter is free of cost and has detailed documentation and communities available online.

4. Native Performance

In Flutter, platform-specific widgets are provided for Google Fuchsia, Android, and iOS. These widgets can be integrated into the Flutter application to make use of the different platform-dependent functionalities. Existing Java, Swift, and Objective-C codes can be used to utilize native features such as camera and geolocation. Therefore, Flutter can easily incorporate third-party integrations and APIs.

5. Minimal Code

Flutter is developed using the Dart programming language. Dart uses JIT and AOT compilation that helps improve the overall startup time, functioning and accelerates the performance. JIT enhances the development system with the hot reload function. It refreshes the UI without putting in the effort to build a new one.

Pros and Cons of Flutter

Pros

  • Faster code development
  • Separate rendering engine
  • Suitable for any target platform
  • Increased time-to-market speed
  • Enormous UI customization potential
  • No reliance on platform-specific UI components
  • The app UI and logic don’t change depending on the platform
  • Flutter enables you to make instant changes in the app which is a god-sent when it comes to fixing bugs.
  • With a single code base, quality assurance and testing usually take much less time.

Cons

  • Flutter is a young technology.
  • The apps made with Flutter tend to be weighty ones.
  • Libraries are growing but not yet matured.
  • Dart is not a popular language and if you want to work with Flutter you will have to learn how to use it.
  • While Flutter is popular, it has not been around long enough to have a huge resource base. Therefore, your team will need to write a lot of stuff from scratch.
