Flutter SDK is a powerful and popular open-source framework for building cross-platform mobile applications. It is developed by Google, Flutter developers have created beautiful, fast and native-like user interface for Android and iOS platforms by using a special single code-base. In this article, we will explain you through the process of the Flutter SDK download and installing step-by-step, so you can start your mobile app development journey right away.
What is the Flutter SDK?
Flutter SDK is a software development kit that simplifies the process of creating cross-platform mobile applications. With Flutter, app developers can write a single code-base that runs on multiple platforms, without the need to create separate apps for Android and iOS. The core programming language used in Flutter is Dart, which is designed to be easy to learn and understand.
Features of Flutter SDK
1. Fast Performance: Flutter apps are known for their high performance, unique to the platform for using Dart's just-in-time (JIT) compilation during development and ahead-of-time (AOT) compilation framework during release. This results in the user enjoying smooth animations and a responsive system.
2. User Friendly Interface: Flutter offers a wide range of customizable widgets, to create a truly awesome user interface. These widgets are designed to adapt to different screen sizes and resolutions, ensuring a consistent look across different devices.
3. Hot Reload: One of Flutter's favorite features is its hot reload functionality. This allows developers to see changes made to code almost instantly on the emulator or connected device without needing to restart the app. This feature significantly speeds up the app development process and makes debugging a professional app.
4. Native-like performance: Flutter apps are not just web-based applications wrapped in a container. Instead, they run directly on the device's hardware, providing users with truly native-like services.
5. Open-source community: Flutter has a large and active community of developers who contribute to the growth and development of the framework. This community-driven approach ensures regular updates, bug fixes, and access to a vast repository of third-party packages.
Why should you choose Flutter for your next project?
1. Fast development: Flutter's "write once, run anywhere" approach helps developers save labor by creating a single code-base for both Android and iOS. This reduces development time and accelerates time to market for your app.
2. Reduced cost: Flutter can significantly reduce development costs, with less resources required to maintain separate code-bases due to rapid development.
3. Pixel-Perfect UI: Flutter's widgets are responsively designed to offer pixel-perfect UI elements, ensuring your app looks exactly the same on different devices.
4. Ideal for MVP: If you are testing a concept or building a minimum viable product (MVP) for your startup, Flutter can be a perfect choice due to its rapid development capabilities.
Fultter SDK Download
How to Install Flutter SDK on your Window, MacOS and Linux
Here, we will explain Fultter SDK installing step by step instructions for all operating system. For install the software following below..
Step 1: Install the Flutter SDK
Before we begin, make sure you have the following prerequisites installed on your computer:
- Operating System: Flutter supports Windows (7 or later), macOS (Xcode 12.0 or later), and Linux (64-bit).
- Disk Space: Make sure you have at least 400 MB of free disk space.
- Command Line Tools: For macOS users, Xcode needs to be installed with command line tools.
Now, let's proceed with the installation process:
1. You can download Flutter SDK by clicking the "Get Started" button displayed on the homepage of Flutter official website or you can also download Flutter SDK from the link we have added below.
2. Select and download the correct version of Flutter SDK for your operating system For example, if you are using Windows, download the Windows version.
3. Extract the downloaded zip file to a location of your choice. For simplicity, you can extract it directly to your C:\ drive on Windows or the home directory on macOS and Linux.
4. When the extraction is complete, add the Flutter SDK's `bin` directory to your system's PATH variable. This step is very important to run Flutter commands from any terminal or command prompt.
For Windows:
- Open Control Panel and search for "Environment Variables".
- Click on "Edit System Environment Variables".
- Click on "Environment Variables" at the bottom right.
- Select the "Path" variable under "System Variables" and click "Edit".
- Click "New" and add the path to the `bin` folder of the Flutter SDK (eg, C:\flutter\bin).
- Click "OK" to save the change
For MmacOS and Linux:
Open a terminal window and run the following command to open the bash profile file:
- bash
nano ~/.bash_profile
Add the following line to the file (replace <path-to-flutter-sdk> with the original path):
- bash
export PATH="$PATH:<path-to-flutter-sdk>/bin"
Save and exit the text editor by pressing Ctrl + X, followed by Y, and then hitting Enter.
To verify the Flutter installation, open a new terminal or command prompt window and type:
flutter doctor
The command will check your system for missing dependencies and display a report. If everything is set up correctly, you will see a message "No problems found!" If not, follow the recommendations provided to resolve the issues.
Step 2: Set up Android Studio (optional but recommended)
While you can use any text editor or IDE to develop Flutter applications, Android Studio offers excellent support for Flutter development. If you don't have it installed, follow these steps:
1. Download Android Studio from the official website or above given link.
2. Install Android Studio by following the on-screen instructions.
3. Launch Android Studio and open "Plugin Preferences" (Preferences on macOS, Settings on Windows and Linux).
4. Select "Plugins" from the left sidebar and then click "Browse Repository".
5. Search for "Flutter" and click on the "Install" button.
6. Restart Android Studio to apply the changes.
Step 3: Run your first Flutter app
Congratulations! You have now set up the Flutter SDK on your computer Let's build and run a simple Flutter app to make sure everything is working properly:
1. Open a Terminal or Command Prompt window.
2. Navigate to your desired location for the Flutter project using the `cd` command.
3. Create a new Flutter project with the following command:
luaflutter create my_first_app4. Change directory to your newly created project:
- bash
cd my_first_app
5. Connect your Android or iOS device to your computer, or launch an emulator.
6. Run the app using the following command:
arduinoflutter run
Flutter will compile your app and install it on the connected device or emulator.
Hopefully! In this article, we have been able to fully explain the process of downloading and setting up Flutter SDK on your computer. I have mentioned how to install and run Flutter app. Now, that you are all set up, you can start the mobile app development process with Flutter
