Flutter : The Secret Weapon for Stunning Mobile Apps
In this article, we’ll learn about Flutter.
Table of Contents
In the field of creating mobile apps, Flutter, Google’s open-source UI development platform, has been making waves.
Flutter, which is well-known for enabling the creation of natively developed desktop, web, and mobile applications from a single codebase, comes with several benefits and drawbacks that programmers should take into account.
To assist you in deciding if it is the best option for your upcoming project, we’ll examine all sides of the Flutter controversy in this post.
What is Flutter
Flutter is an open-source framework for building beautiful, natively compiled, multi-platform applications from a single codebase.
This framework is created by Google. It is used to develop high-performance, cross-platform mobile applications for iOS, Android, and web platforms using a single codebase.
Its rich set of pre-built widgets, hot reload feature, and native-like performance make it a popular choice for mobile app development.
It makes use of the Dart reactive programming language, which makes development faster and easier than traditional methods.
It is a Google UI toolkit for creating beautiful, natively compiled applications for mobile (Android, iOS), desktop (Linux, Mac, Windows, Google Fuchsia), and web from a single codebase.
The first version of it codenamed “Sky,” was released in 2015 at the Dart Developer Summit and ran only on the Android operating system. Flutter 1.0, the first “stable” version of the Framework, was released at the event on December 4, 2018.
Dart, a simple object-oriented programming language, is used to create Flutter apps. Widgets are at the heart of it’s design.
It’s efficiency has vastly improved since then. It Interact was held on December 11, 2019, and it brought a range of changes to the system with the release of Flutter 1.12.
When discussing the best way to learn Flutter, it’s important to note that Flutter consists of two key components:
- SDK (Software Development Kit): This includes a comprehensive set of tools that assist in developing your application, such as those needed to compile code into native machine language.
- Framework (UI-based Library): This is a collection of reusable UI components, such as text inputs, buttons, and sliders, which you can customize to fit your requirements.
Why Use
- Cross-platform Development: Because It is a cross-platform development framework, you can use it to create apps with a single codebase for both Android and iOS devices. This saves a lot of time and exertion contrasted with building separate applications for every stage.
- Fast Development: Because it has a hot reload feature that lets developers see the changes they make in real-time, it has a fast development cycle. The development process is streamlined and accelerated as a result.
- Beautiful UIs: Developers can quickly and easily create beautiful and highly customized user interfaces (UIs) with it’s extensive set of pre-built widgets and tools. It also has a rendering engine, which makes UI rendering quick and smooth.
- High Performance: Dart is a compiled programming language that outperforms interpreted languages in terms of performance and startup speed. This improves the user experience by making applications run more quickly and smoothly.
- Growing Community: Since the developer community for it is expanding, there are a lot of tutorials, blogs, and forums online to assist with development. This makes it simpler to begin using it and to locate assistance when required.
- Cost-effective: When compared to other native app development frameworks like Java or Swift, developers can construct cross-platform applications at a lower cost with it. This is because developers can save money on development and upkeep by using a single codebase to create apps for multiple platforms.
Prerequisites to Learn
Before you begin learning Flutter and building your first Flutter app, you should be familiar with the following concepts. If you’re not comfortable with any of these, it’s best to learn them first:
- Understanding OOP Concepts: It’s crucial to have a solid grasp of Object-Oriented Programming (OOP) concepts, as they are the foundation of languages like Java and C++.
- Knowledge of C++/Java: While detailed knowledge of C++ and Java is not mandatory, having a background in these languages can be beneficial.
- Familiarity with Native Android Development: Knowing how to develop native Android applications will help you create finely detailed apps. You can also find resources on improving Android app performance to aid in this learning.
- Learning Dart Programming: Familiarity with Dart programming is essential before learning Flutter. Dart, Google’s general-purpose programming language, is easy and straightforward to learn.
Installation:
- Download Flutter SDK: Download the latest version of Flutter SDK for Windows from here: Download Flutter SDK for Windows
- Extract Files: After downloading, extract the contents of the zip file into a preferred folder location, such as C:\flutter.
- Setting up Environment Variables: If you prefer using commands in the standard Windows console, follow these steps to add Flutter to the PATH environment variable:
- Open the Start menu, search for ‘env’, and select “Edit environment variables for your account”.
- Check under User variables if there’s an entry named Path:
- If it exists, append the full path to flutter\bin using ; as a separator from existing values.
- If it doesn’t exist, create a new user variable named Path and set its value to the full path of flutter\bin.
- Remember to close and reopen any existing console windows for these changes to take effect.
- Verification: Congratulations on installing Flutter SDK on Windows! To ensure everything is set up correctly, execute the “flutter doctor” command in your terminal. This command will assess your environment and display the status of your Flutter installation. If any necessary items are missing such as Android SDK or IDE like Android Studio or VS Code, the flutter doctor will provide recommendations for installation.
Advantages and Disadvantages:
Advantages:
- Single Codebase, Multiple Platforms: The ability to create apps for many platforms, such as iOS, Android, the web, and desktop, while only requiring a single codebase, is one of it’s biggest advantages. This expedites development, saves time and effort, and ensures platform consistency.
- Fast Development: Faster and more effective development is possible because of Flutter’s hot reload functionality, which enables developers to view changes immediately. It’s great for experimenting and perfecting the user interface of your app.
- Beautiful UI: Beautiful user interfaces are simple to construct with It’s vast selection of pre-designed widgets and customizable choices. The Cupertino and Material Design widgets guarantee a native appearance and experience on both Android and iOS.
- High Performance: Smooth animations and quick rendering are made possible by the high-performance architecture of it. It compiles native ARM code and makes use of the Skia graphics engine to produce exceptional app performance.
- Active Community: It has an active developer community that frequently contributes packages and plugins to improve functionality. This implies that you have access to a wealth of resources and can solve common problems.
Disadvantages:
- Larger App Size: Because the Flutter engine is incorporated into Flutter apps, they often have a greater file size than their native counterparts. Users who have run out of storage capacity on their smartphones may find this to be a problem.
- Limited Native Features: Despite offering a large selection of widgets and libraries, it might not be able to support all native features or APIs offered on every platform. For some functionality, developers might need to build platform-specific code.
- Learning Curve: If you’re new to it, there can be a learning curve as you become used to the programming language Dart and the distinctive architecture of the framework. This may slow down initial development.
- Community and Ecosystem Maturity: The community of it is vibrant and expanding, although its ecosystem may not be as developed as that of some other frameworks, such as React Native. Less use of third-party libraries and tools may result from this.
