Introduction

In this article, we will learn how to install Flutter. And set up the environment for different IDE. Android Studio is a popular IDE for creating cross-platform Android apps that were developed by Google. First, you'll need to download and install Android Studio 3.0 or later, including an integrated IDE for Flutter.

Windows install

System Requirements

Your development environment must match the following basic requirements in order to install and execute Flutter:

OS: Windows 10 or later (64-bit), x86-64 based 

Disk Space: 1.64 GB (does not include IDE/tools disc space).

Flutter relies on the presence of these tools in your environment.

  1. Windows PowerShell 5.0 or later is required (this is pre-installed with Windows 10)
  2. Use Git from the Windows Command Prompt option in Git for Windows 2.x.

Make that you can run git commands from the command prompt or PowerShell if Git for Windows is already installed.

Set up Flutter SDK

1. To receive the newest stable release of the Flutter SDK, go to the official flutter site and download the installation bundle click here.

2. Extract the zip file and place the contained flutter in the Flutter SDK's selected installation folder (recommended location: C:\src\flutter).

Update path

If you want to use the conventional Windows console to perform Flutter commands, follow these steps to add Flutter to the PATH environment variable:

1. Enter 'env' in the Start Search bar and choose Edit environment variables for your account.

2. Look for an entry called Path: under User variables.

If the entry already exists, insert the whole path to flutter\bin, separating existing values with ’;’

3. Create a new user variable named Path with the complete path to flutter\bin as its value if the entry doesn't exist.

For these modifications to take effect, you must shut and reopen any existing console windows.

To ensure everything is okay run the command flutter doctor from the command line. Don’t worry about missing android SDK, we’ll install it next.

Android setup

Install Android Studio

1. Install Android Studio on your computer.

2. Launch Android Studio and follow the 'Android Studio Setup Wizard' instructions. The latest Android SDK, Android SDK Command-line Tools, and Android SDK Build-Tools are installed, which are required by Flutter when working for Android.

3. Run flutter doctor to see if Flutter has found your Android Studio installation. If Flutter can't find it, use flutter config —android-studio-dir<directory> to change the Android Studio installation directory.

Set up your Android device

You'll need an Android smartphone running Android 4.1 (API level 16) or higher to run and test your Flutter app on an Android device.

1. On your device, enable Developer settings and USB debugging. The Android documentation contains detailed instructions. To enable developer options in your mobile phone, check as per need as it is different for each device.

2. Install the Google USB Driver if you're using Windows.

3. Connect your phone to your computer with a USB cable. Allow your computer to access your device if prompted by your device.

4. Run the flutter devices command in the terminal to see if Flutter recognizes your connected Android device. Flutter uses the version of the Android SDK that your adb tool is built on by default. You must set the ANDROID SDK ROOT environment variable to the location where the Android SDK is installed if you want Flutter to use it.

Agree to Android Licenses

Before you may utilize Flutter, you must agree to the Android SDK platform's licensing. After you've installed the tools described above, proceed to the next step.

1. Make sure you have Java 8 installed and that your JAVA HOME environment variable points to the JDK subdirectory. This should already be done if you're using Android Studio 2.2 or higher, as it comes with a JDK.

2. To begin signing licenses, open an elevated terminal window and type the following command.

 flutter doctor --android-licenses

3. Before consenting to the conditions of each license, read them thoroughly.

4. After you've agreed to the licensing, run flutter doctor once more to make sure you're ready to utilize Flutter.
